An Analysis Of The Environment Use Efficiency And Its Regional Difference

Owing to the rapid industrialization, China has made remarkable achievements in economic development; however, this also led to shocking environmental cost, so putting environmental consumption into GDP accounting is essential. At the same time for China such a big and uneven development country, the differences observed in the provinces on the environment use efficiency is also important. This paper constructs a half parameter stochastic frontier model with non-observation of interaction, by putting environmental pollution into the production function framework, based on Chinese provincial panel data, to measure the efficiency of China environment use and regional differences.Our results show that environment efficiency exhibits non-equilibrium pattern that developed regions significantly biased efficient, and partial backward areas significantly inefficient. From the pattern of technical efficiency, the non-quantitative factors common presents upward trend, which coincide with the long-term economic growth and technological progress elastic analysis results. In the eastern provinces of the trend is more sensitive to changes in technology, Beijing was 0.24, Shanghai was 0.22, Ningxia was 0.098, Yunnan was 0.105 and Xinjiang was 0.119. Further illustrates the more economically developed provinces, in the process of economic and social development of technology has sensitive rigidity, the higher technical efficiency. From the individual effect, which reflects the economic structure, its rationality and perfect in the eastern provinces is the highest, then the central region, the lowest in the western region, where Beijing 0.1499 becomes the lowest individual effects in eastern provinces.Overall, technical efficiency, spatial differences in economic structure is the main reason to differences in environmental efficiency. Technology developed, economic structure perfect province environment- economic effect is remarkable, but technology backward province has a greater sacrifice. Policy recommendations should be from balance technology, encourage high and new energy industries, to speed up the strategic adjustment of economic structure and restore economic growth accounting system etc.
