To maximize the output of an energy and chemical industry zone under certain resources consumption, the distribution of resources between enterprises should be optimized. The relationship between the output and the various production factors was analyzed. And on the basis of Cobb-Douglas production function, a generic production function that could describe the production trait of a energy and chemical enterprise was generated. Through further assumption and simplification, the relationship between output and resources comsumption was derived, which simplifies the calculation of optimization of resources distribution as computable linear programming. To avoid that certain enterprise had no resources via optimization, the linear programming should be subject to artificial lower limit constraint of gain. Jinjie industry zone in Shaanxi province was taken as an example to explain the optimization method resulting in that the gain of this industry zone increased 76.0% without lower limit constraint of gain and 26.8% with lower limit constraint of gain after optimization. As for industry zone under planning, maximum output of overall industry zone as well as profit margins of each enterprise could be obtained by this method, while those constructed could only obtain a maximum output because scale of each enterprise can't be changed. This method could be a reference for the optimization of resources distribution or the enterprise scale in an energy and chemical industry zone.
