基于DEA的中国经济增长资源利用效率探讨

A Study of China’s Efficiency of Resource Use in Economic Growth Based on DEA

采用DEA模型和Malmquist(曼奎斯特)生产率指数对中国1978年～2011年资源投入产出效率及全要素生产率增长构成进行分析,同时将中国资源投入产出效率与一些主要国家资源投入产出效率进行比较,结果显示,中国资源投入产出纯技术效率和规模效率有效,技术进步变化引起了全要素生产率整体提高。相对美国、日本、巴西等6个国家,中国全要素生产效率水平居中,但技术变化指数和纯技术效率指数均小于1,存在投资效率下滑态势。

By using DEA model and Malmquist productivity index,this paper does China’s 1978-2011 resource inputoutput efficiency and total factor productivity growth constitute analysis,and compares the input-output efficiency of China＇s resources with that of some other major countries.The results show that 1978-2011 resource input-output is of pure technical efficiency and scale efficiency,and technological advances change the overall improvement of total factor productivity.In addition,relative to the United States,Brazil,and several other major countries,China＇s total factor productivity comes up to medium level,technical change index and pure technical efficiency index are less than 1,showing a decline in investment efficiency.
