Environmental Performance Analysis Of Manufacturing Enterprises Of Green Supply Chain

Environmental issues not only directly affect the sustainable development of society and economy,and have become a global problem that troubled human survival and development.Green supply chain combines supply chain management with the values of sustainable development,considering the environmental impact and resource efficiency during the supply chain management.Currently,there are many experts and scholars researching in the concept and the development trend of green supply chain,and comparing the green supply chain advantages to the traditional supply chain,but few articles do research in economic performance and environmental performance of green supply chain.In this paper,it selected manufacturing enterprises of green supply chain(iron and steel enterprises)as the research issues,analyzed the resource consumption and pollutant emissions of iron and steel enterprises,and found that tons of steel in units of normalized environmental data,because of no relationship,are effective only on the simple sort of individual environmental indicators,not on their overall environmental performance of a comprehensive evaluation.This paper suggested that the use of per RMB 10000 turnover in units of enterprise resource consumption and pollutant emissions normalized process,is a strong positive correlation between per RMB 10000 turnover of enterprises with the comprehensive energy consumption and pollutant emissions.In the fourth part,it constructed an input-output model taking the desirable and undesirable output into account,and selected Chinese steel enterprises as the research issues researching the efficiency of their desirable and undesirable outputs,to test the validity of the model.The empirical results fully proved the environment efficiency model which based on C2 R model and taking into account the desirable output and undesirable output of steel enterprises is effective.This study will help iron and steel enterprises in the implementation of benchmarking management clearly their own target on the management,but also indicate direction to improve input and output efficiency.
