    Nowadays, although global economic rebalancing has made great progress, seeking inclusive growth is still an important issue to be solved. We propose a global value chain-based accounting framework to quantify the global trend of inclusive growth, and further use structural decomposition analysis (SDA) to explore the driving factors accounting for the change of inclusive growth. Finally, considering the deviation between domestic value-added and national income, we also conduct a comparative study on the inclusiveness of global economic growth under the territorial and ownership calibers. We find that the global income gap (especially south-north gap) under the territorial and ownership calibers shows a downward trend, indicating that the inclusive level of global economic growth is improving. However, it should be alert that the global economic inclusive growth measured by national income shows sign of deterioration at the end of the analysis period. Further analysis shows that the input structure, final demand and population jointly contribute to the reduction of the global income gap. Among them, the derivation of value-added ratio between North and South has widened the global income gap, which is offset by the increasingly strengthened intermediate and final trade linkages between North and South. In addition, the expansion of final demand scale is also an important factor to narrow the global income gap. Our paper sheds light on the global economic inclusive growth and its driving factors, and also on how to boost inclusive growth.

    This article establishes a multi-period DID model using the phased implementation of state-owned capital authorization management reform, and confirms that the reform of state-owned capital authorization management is beneficial for alleviating the tax burden on state-owned enterprises. In mechanism testing, the reform of authorized operations takes the implementation of market-oriented incentives and strengthening information transparency as a two-way path, which affects the tax burden of state-owned enterprises by increasing their profit motivation and increasing the difficulty of tax deviation. The heterogeneity analysis focusing on equity structure found that the above relationship is more significant in central enterprises, state-owned enterprises with high equity concentration, low equity balance and high regional economic development level. The research conclusion is conducive to expanding the policy effectiveness evaluation dimensions of authorized operation reform, providing direct empirical evidence for reducing government intervention and alleviating policy burden in authorized operation reform, and making incremental contributions to deepening theoretical exploration of authorized operation reform and supplementing factors affecting corporate tax burden.

    Increasing labor income share is the core essence of optimizing the income distribution pattern and achieving common prosperity. This paper examines the impact of local fiscal pressure on the labor income share of enterprises using difference-in-difference method with a quasi-natural experiment of the nation-wide abolition of agriculture tax in 2005. We find that local fiscal pressure significantly reduces the share of labor income of enterprises. Moreover, we find that the negative relationship is more pronounced in small and medium-sized enterprises, regions with lower financial development, regions with lower fiscal self-sufficiency, and firms in labor-intensive industries. Further mechanism analysis shows that fiscal pressure leads local governments to raise tax and non-tax enforcement, increase debt raising, and thus intensify firms' financing constraints. Financing constraints firms cut human capital investment to smooth out fixed asset investment, which in turn leads to a decrease in firms' labor income share. This study not only enriches the research on local fiscal pressure and labor income share of enterprises, but also provides empirical evidence and policy implications on how to improve the primary distribution structure and achieve common prosperity.

    In this study, the impact of renewable energy technological innovation (RETI) on city-level energy transition and its mechanisms are investigated in 279 Chinese cities from 2005 to 2019. The results show that, on the whole, RETI has significantly contributed to city-level energy transition, but the real contribution was made after 2011, and the contribution to the energy transition was significantly stronger in cities located in the Southwest region than in other cities. In addition, RETI has a significant contribution to the energy transition in cities with a relative abundance of renewable energy and a relative scarcity of fossil energy, but the opposite is true for cities with a relative scarcity of renewable energy and a relative abundance of fossil energy. These findings hold after circumventing sample selection bias, endogeneity, and special sample interventions. Further studies found that reducing energy costs, increasing the economic penetration of renewable energy, and reducing pollution emissions are the key channels through which RETI drives city-level energy transition. This study is the first to reveal the mechanism of RETI on energy transition at the city level, which helps to promote the implementation of national and provincial energy development strategies to the city level, and provides strong support to promote city-level energy transition with high quality.

    China is currently undergoing a dynamic process of evolution in the government-business relationship, with a transition from old to new forms. A new type of government-business relationship that emphasizes "cordiality" and "cleanliness" has become the fundamental approach for governments at all levels to improve this relationship. Examining whether such a relationship can better promote entrepreneurial spirit and drive regional innovation and entrepreneurship is of great significance. This study employs national industrial and commercial enterprise registration data and the China cordial and clean government-business relationship index to construct an annual observation sample of Chinese cities at or above the prefecture level from 2016 to 2019, empirically testing the impact of cordial and clean government-business relationships on regional entrepreneurship levels and its mechanism. The findings are as follows: First, a higher degree of cordial and clean government-business relationships leads to greater improvement in regional entrepreneurship levels. On average, a 10-point increase in the cordial and clean government-business relationship index corresponds to a 2.35% increase in the number of entrepreneurial enterprises in the city, with significant economic implications. Second, cordial and clean government-business relationships play a "cost-saving effect" and "income incentive effect" in empowering regional entrepreneurship and optimizing its structure. Third, the positive impact of cordial and clean government-business relationships on regional entrepreneurship levels is stronger in non-eastern regions, small-scale, and lower-level cities, indicating a "supporting the weak" effect. Fourth, the promoting effect of cordial and clean government-business relationships on regional entrepreneurship levels is stronger when their institutionalization in the region is higher and official media propaganda is stronger. Fifth, this study finds that cordial and clean government-business relationships can significantly improve the entrepreneurial probability of micro individuals, particularly in opportunity-based entrepreneurship, with a stronger empowering effect. In conclusion, the research findings not only enrich the literature on government-business relationships and regional entrepreneurship but also provide timely decision-making support for the current reform practice of building a new type of cordial and clean government-business relationship system in China.

    By constructing a two-stage model of dynamic R&D investment of enterprises under own capital investment (OC), independent venture capital (IVC) financing, and corporate venture capital (CVC) financing, this study explores the influence of different financing modes on the dynamic R&D investment decision made by enterprises. The results show that, IVC financing always promotes R&D investment of enterprises in the second stage. It can also promote the R&D investment of enterprises in the first stage when the success probability of R&D projects is higher than a certain threshold. CVC financing can promote R&D investment of enterprises in the first stage when the success probability of R&D project is higher than a certain threshold and the strategic synergy of the R&D project for the CVC parent company is greater than the risk-free project. Compared with IVC, CVC can better promote the R&D investment of enterprises in the first stage, but if the result of the R&D project in the first stage is low quality, IVC can better promote the R&D investment of enterprise in the second stage.

    This paper empirically examines the relationship between customer enterprises' ESG rating and supplier enterprises' green innovation, using all A-share listed companies from 2009 to 2022 as the research samples. The empirical results show that customer enterprises' ESG rating can positively influence supplier enterprises' green innovation; customer enterprises reduce the amount of funds absorbed from supplier enterprises, encourage supplier enterprises to increase innovation investment, and improve the managers' green cognition of supplier enterprises are the three mechanisms of promoting supplier enterprises' green innovation through customer enterprises' ESG rating; supplier enterprises' market power will negatively moderate the positive relationship between customer enterprises' ESG rating and supplier enterprises' green innovation. Heterogeneity analysis shows that the positive influence of customer enterprises' ESG rating on supplier enterprises' green innovation is more significant both when customer enterprises are under greater legitimacy pressure or have more substantive ESG practices, and when supplier enterprises lack credibility or face stricter environmental regulations. Further research shows that customer enterprises' ESG rating is more effective in promoting supplier enterprises' green innovation when the uncertainty of ESG rating results is low, and that supplier enterprises' green innovation contributes not only to supplier enterprises' own ESG rating but also to supplier enterprises' total factor productivity. This paper highlights the spillover effects of ESG rating pressure from the perspective of supplier enterprises, and provides empirical evidence and management enlightenments for effectively promoting enterprise green innovation.

    The inequality between economic trade benefits and carbon emission costs among cities not only reveals the inherent interaction of cities' carbon decoupling processes among but also reflects the heterogeneity of their industrial division and economic structure. Existing carbon-decoupling index models insufficiently consider the impact of intercity carbon inequality, thereby leading to the ambiguity in the development trend of industrial carbon emissions with the urban carbon decoupling progress. Therefore, this study combines input-output analysis framework and complex network methods to construct a novel carbon decoupling index model considering carbon inequality relationships. Subsequently, this study empirically analyzes the grouped development patterns of carbon emissions in various industries under China's urban carbon decoupling process in 2012, 2015, and 2017, with a focus on 309 cities. The results indicate that the distribution of carbon inequality between Chinese cities exhibits a clear demand-side concentration feature. In recent years, the carbon decoupling benefits obtained by major Chinese cities through carbon inequality have continuously increased, becoming a crucial factor in achieving low-carbon development in their production activities. With the advancement of carbon decoupling, the interdependence of city-level industrial carbon emissions demonstrates a "U"-shaped development trend, initially decoupling and then recoupling. This study contributes to enhancing the understanding of the impact of cross-regional economic environmental connections on urban carbon decoupling development. It can help city managers at different development stages formulate differentiated policy combinations to achieve stable economic development and multi-industry collaborative emissions reduction.

    The pollution control strategy of enterprise is not only affected by perceived pressures, but also closely related to enterprise's own resources that can be allocated. Therefore, from the perspective of configuration, this paper analyzes what kind of pressure perception and social capital combination can promote enterprises to adopt high-level environmental pollution control strategies from the perspective of configuration. The results showed that: 1) The effective pollution control mode of enterprises can be mainly divided into three categories: Pollution control path led by government supervision and social relations, the pollution control path driven by social relations led by capital, and the pollution control path driven by social relations led by R&D. 2) "Government pressure" and "R&D platform participation" are important factors that promote enterprises to adopt high-level pollution control. The group of high-politically embedded enterprises, small-sized enterprises, and enterprises in the industrial undertaking zone has a configuration with "government pressure" as the core condition, while the group of low-politically embedded enterprises, large-sized enterprises, and enterprises in the industrial relocation zone has a configuration with "R&D platform participation" as the core condition; 3) Good social relations among entrepreneurs are the basic guarantee for all kinds of enterprises to achieve high-level pollution control. In Chinese manufacturing business environment, fully mobilizing the role of entrepreneurs' social relations is conducive to promoting the high-level pollution control process of various enterprises. The results of this study are helpful to clarify the driving path and mechanism of high-level pollution control behavior of manufacturing enterprises, provide a theoretical basis for enterprises to achieve the phenomenon of "different paths to the same end" of high-level pollution control, and provide scientific guidance for fighting the tough battle of pollution prevention.

    The environmental benefits of transportation have always been a focus of environmental economics. However, due to data availability and endogeneity issues, there is limited research on the impact of urban rail transit on ambient air quality at a national level. This study innovatively matches data on subway segments in 39 Chinese cities with a high-resolution daily PM2.5 dataset, and employs a multi-period difference-in-differences approach to empirically analyze the causal relationship between the opening of new subway segments and local air pollution. The study finds that the opening of new subway segments significantly improves ambient air quality, leading to a reduction of approximately 2.37µg/m3 in PM2.5 concentration within a 500-meter radius. Moreover, this pollution reduction effect is more pronounced on weekdays in cities with high per capita GDP, heavy air pollution levels, and large-scale coal-fired power plants, or on the initial subway section of a certain line, as well as in the initial segments of certain subway lines. This impact may be attributed to the diversion of public transportation passenger flows from surface transportation, resulting in a decrease in vehicular traffic on the surface. Furthermore, the study identifies network effects of subway openings, as the opening of new segments improves air quality around existing subway segments, and the degree of improvement is higher for existing segments that have closer connections to the newly opened segments. The estimation of health benefits indicates that the opening of subway segments reduces premature deaths caused by PM2.5, bringing about an estimated economic value of approximately 11.4 to 28.5 billion yuan in terms of improved health for the population covered by the subway. The findings of this study provide theoretical and empirical evidence to better understand the causal relationship between subway construction and air quality, and offer insights for the scientific planning and development of urban rail transit, contributing to urban environmental governance and sustainable development.

    Under the dual-carbon goal, it is a foundation for achieving low-carbon transition of supply and demand about how demand promotes enterprises' green production and the cost transfer of green production inhibits consumption. we nest the consumption value into the utility function of consumers, and then develop enterprises' green production decision-making models where the boundary conditions of low-carbon production are identified and the inhibitory mechanisms of cost transfer on consumption are examined. The results show that: Consumption value drives demand structure and enterprise production towards low-carbon, which can be strengthen by the dual-carbon goal; the relationship between carbon price and investment revenue plays a key role in enterprises' production paths, and there is a threshold value for investment revenue; if the revenue exceeds the threshold, carbon price stimulates enterprises to invest in emission reduction, but it has a negative impact on output, and its impact degree will be weakened with the implementation of carbon-abating goals, forming an inverted U-shaped trend; the cost transfer leads to demand structure to be low-carbon upgrade.

    Grey market is formed in the arbitrage opportunity brought by the price difference of the same type of merchandise in different regions, which widely exists in the marketing cycle of brand products. At the same time, brand manufacturers strategically choose the release time of products in different channels to alleviate channel conflicts. For example, compared with the synchronization strategy (release of products in both high- and low-price market, simultaneously), the postponement strategy (release of products in high- and low-priced markets, successively) is one of the most common marketing strategies. Based on it, this paper considers a production and marketing system consisting of two manufacturers, one third-party speculator and customers. Aiming at the channel selection strategy of the powerful manufacturer in the grey market environment, the channel model decision models of the powerful manufacturer with synchronous strategy and postponement strategy are constructed respectively. By comparing and analyzing the influence of the grey market and the channel models on the decision-making of the powerful manufacturer. The results show that: 1) When the third-party participates in speculation in the grey market, it is the best channel strategy for the powerful manufacturer to adopt postponement strategy; 2) the pricing strategy of the powerful manufacturer depends on the channel model selection strategy; 3) the involvement of the third-party speculators in the grey market is closely related to the transfer costs, consumers' valuation of products and the degree of substitution of products in different markets. In addition, we also analyzes the influence of the different channel strategies of the powerful manufacturer on the low-price market product pricing of the general manufacturer.

    This paper considers an agricultural supply chain consisting of a downstream company and a farmer in the presence of the latter having the adulteration behavior of agricultural raw-material products, in which the downstream company promises to purchase all the effective agricultural raw-material products of the farmer with a procurement price, and the latter determines the amount of brand and counterfeit agricultural raw-material products. Then, we develop a stylized model under the settings with non-blockchain-based (traditional technology-based) traceability and blockchain-based traceability. Our results show that under the blockchain-based traceability, the downstream company can restrain the farmer' enthusiasm to produce the counterfeit raw-material products via the procurement price. In addition, under some mild conditions, the blockchain-based traceability has significantly impact on inducing the farmer to produce less counterfeit raw-material products, and makes the farmer produce more brand raw-material products. However, it is interesting to show that blind pursuit of curbing adulteration by the farmer does not necessarily bring more profits to all the parties. Further, we find that under some cases, choosing the blockchain-based traceability can reach a "win-win" situation for the two parties. Moreover, the blockchain-based traceability does not always cause the company to offer a higher retail price of the final agricultural products, and consequently, consumer surplus is not always improved.

    Identifying key nodes in emergency logistics networks contributes to the deployment of maintenance measures, ensuring the stability of emergency logistics networks. We introduce a cooperative game theory approach to identify key nodes in the emergency logistics networks. By defining the feasible coalition and coalition utility in the emergency logistics network, a single-valued solution in the emergency logistics network is proposed based on the Shapley value, which is used as the measurement method of node centrality in the emergency logistics network. Firstly, it is proved that the centrality of nodes calculated by this single-valued solution is mutually independent among different independent emergency logistics networks, which reduces the computational complexity. Secondly, the feasible component efficiency and road fairness are defined, and it is proved that this solution is the unique single-valued solution satisfying the two axioms mentioned above. Finally, the rationality and robustness are illustrated by numerical examples. Taking the single-valued solution as the measurement method of node centrality in an emergency logistics network can not only fully consider the topological characteristics of the network, but also take into account the non-network characteristics of nodes, which provides strong theoretical support for the optimization and stability maintenance of emergency logistics networks.

    Since innovations rely on the combination and recombination of knowledge elements that are caused by organizational collaborations, innovations are dual embedded in the interdepend networks constructed by knowledge networks and collaboration networks. Accordingly, it has significant implications for maintaining the continuous operation of interdepend networks and preventing the neck problem of innovation by unveiling the destruction of combinatorial relationships of knowledge elements within knowledge networks and the cascade effects of organizational cooperative ties in collaboration networks caused by the failure of knowledge elements based on technical sanction. On the basis of constructing the three-dimensional properties structure ofof the knowledge element, we divide the failure strategies of the knowledge element into six categories. By using the data of the new generation of information technologies industry of China from 2000-2021, we comprehensively reveal the impact of knowledge elements failure on interdepend networks in accordance with the change of resilience of structure and function. Furthermore, drawing on the mechanism of knowledge replacement, we develop the stability strategies of network resilience and explore the ways to guarantee the operation of interdepend networks via the strategies practice simulation. We find that: 1) In the knowledge networks, different knowledge elements were combined following the existing innovation logic. Although knowledge elements were connected as scattered clusters, their contents emerged with the tendency of diversity. Knowledge elements that are characterized by relatively medium expertise but high relativeness can create serious neck problems of innovation. 2) In the collaboration networks, organizations had embedded their multiple knowledge elements into the knowledge networks, the cooperation of organizations was related to several knowledge elements and could not directly break by the failure of one knowledge element. 3) The strategies of the initial calculated-based and recalculated-based obtained similar effects. 4) Three essential ways can maintain the stability of interdepend networks. Including comprehensively combining the knowledge elements with medium-degree, adequately capturing the knowledge combinatorial opportunities that were provided by knowledge elements with medium in-degree, and continuously developing knowledge elements with fundamentality and high relativeness.

    Trust relationship is the main tool to determine the importance of subject in group comprehensive evaluation. However, in the existing research, trust relationship mostly depends on emotional factors and is regarded as static and fixed. This can easily lead to the "trust risk" problem. How to avoid this problem and improve the reliability of trust relationship has become one of the important research contents in group evaluation. To solve this problem, this paper first constructs a trust relationship network based on Page Rank. A dynamic trust relationship measurement method is proposed, which considers affective trust and cognitive trust comprehensively, and realizes the dynamic calculation of the interaction process of trust relationship with groups. Further, a group consensus reaching method based on dynamic trust relationship is proposed to improve the efficiency of consensus reaching. On this basis, a group evaluation method considering the dynamic trust relationship of evaluation subjects is constructed. Finally, the validity and reliability of the method are demonstrated by an example of the selection of major investment projects.

    Cross-efficiency analysis is an important extension of data envelopment analysis, which evaluates decision-making units by integrating both self-evaluation efficiency and peer-evaluation efficiency. Existing Cross-efficiency analysis methods mostly focus on obtaining efficiency results, without considering the relationship between self-evaluation and peer-evaluation efficiencies or the level of acceptance of peer-evaluation efficiency by decision-making units. This paper focuses on the cross-evaluation process and introduces social network analysis to construct a trust network between self-evaluation and peer-evaluation efficiencies, treating the cross-evaluation process as a group decision-making process within the evaluation system. Based on this, a cross-evaluation method based on consensus and trust relationships is proposed. First, the interval cross efficiency matrix is calculated using both benevolent and aggressive strategy. Then, the bidirectional trust network between decision-making units is constructed using social network analysis, which directly associates self-evaluation and peer-evaluation efficiencies. Second, based on the trust network, two indicators, namely recognition consistency and representativeness level, are proposed to assign corresponding weights to decision-making units. Third, a weighted cross-evaluation maximization model is established, and a consensus analysis is performed on the peer-evaluation efficiency values of each decision-making unit to obtain the final cross efficiency value that reflects the consistency and acceptance of peer-evaluation efficiency by decision-making units. Finally, a case study is used to demonstrate the feasibility and practicality of the proposed method.

    In recent years, the emergence of customized buses has provided convenient services for commuters. However, changes in road conditions, attributed to factors such as traffic congestion, bad weather, and car accidents, have increased passenger travel time and significantly impacted the punctuality of bus operations, diminishing the appeal of customized bus services. This study addresses a new commuting customized bus network design problem. It takes into account uncertain road conditions, passenger separation, and the presence of heterogeneous vehicle models. We first formulate it into a multi-objective robust optimization model based on the minimum-maximum regret criterion. This model optimizes the selection of heterogeneous vehicle models, fleet routes, travel times, and passenger assignments with the aim of minimizing both passenger travel costs and bus system operating costs. Then, to effectively solve the model, we propose a multi-objective hybrid adaptive large neighborhood search algorithm. This algorithm incorporates problem-specific characteristics, introduces a passenger separation destruction operator based on these characteristics, and integrates a crossover operator to enhance the algorithm's optimization capability. Results of extensive numerical experimental results indicate that: i) The consideration of passenger separation and heterogeneous vehicles leads to improved vehicle resource utilization efficiency. Considering passenger separation results in an average time savings of 2.44% and a reduction of 11.46% in operating costs. Similarly, the inclusion of heterogeneous vehicle models yields an average time savings of 1.74% and a decrease in operating cost by 24.95%. ii) Compared with the traditional large neighborhood search algorithm and NSGA-II, our proposed algorithm consistently produces higher-quality Pareto solutions. iii) when compared to solutions obtained under deterministic road conditions, the solutions obtained in the presence of uncertainty in road conditions achieve an average reduction of 1.42% in passenger travel cost and a decrease of 18.24% in operating cost. This confirms the necessity of conducting robust commuting customized bus network design research under uncertain road conditions.

    Automated guided vehicles (AGVs) are a key factor in determining the operational efficiency of automated container terminals. AGVs often face travel time uncertainties due to congestion, conflicts, weather, and other factors, resulting in quay and yard crane delays that reduce operational efficiency. In this paper, we introduce a distributionally robust method based on Wasserstein distance using historical travel data. We construct a data-driven model to manage the risk of waiting at quay cranes and yard cranes and to determine the task allocation scheme for AGVs with minimal operating costs. To solve the model, we first use conditional value-at-risk to approximate the distributionally robust chance constraints. Its closed-form solution is obtained by duality theory and analytic transformation, which are then transformed into a practical form. Secondly, exact branch-and-cut algorithms, along with heuristic algorithms and corresponding acceleration strategies, are designed for problems of varying sizes in automated container terminals. Experimental results demonstrate that the distributionally robust optimization method effectively captures the uncertainties in AGV travel times. Compared to the sample average approximation, the model and solution proposed in this paper can reduce the risk of waiting at quay cranes and yard cranes by 60%, significantly enhancing the robustness of the allocation scheme.
