Analysis On Green Economic Efficiency Of Resource-Based City Based On The Non-Parameter Estimation And Tobit Model

This article adopts the data from 2002 to 2012 studying the development of green economy of resource-based cities, in order to make its sustainable development performance clear. By the application of directional distance function in data envelopment analysis, the efficiency of green economy can be estimated with the imput data in labor, capital,land, water, electricity and other resource inputs and the output data in real GDP and sulfur dioxide emissions. To make the impact factor clear, the contribution rate of each imput and output to the inefficiency of green economy in 2012 is studied by the method of structure analysis.Research shows that some resource-based cities like Anshan are always in the green economy efficiency frontier, whose distribution in the whole country shapes like a saddle. Most cities in the east and west are at the top of the efficiency ranking and many cities in the middle are at the bottom. The green economic development should be accelerated. Although on the whole the green economic efficiency is rising from 2002, obvious differences still exist in different regions. By further studying on the inefficiency of green economy, the impact factors can be found. The conclusions of Tobit regression are followings.Generally, there is a "U"-type relationship between domestic economy and the green economic efficiency and China is in a stage of decline. "Pollution Heaven" hypothesis and "Structural Bonus" hypothesis are invalid. Factor endowment has no impact on the development of green economy. Government controlling on pollution has significant influence on green economy. However, living sewage treatment rate has negative impact on green economy. Stronger ability in controlling pollution of enterprises can vigorously promotes the development of green economy.Regionally, "Pollution Heaven" hypothesis is invalid and differences in factor endowment have a tiny effect on the development of green economy. "Structural Bonus" hypothesis is valid only in the east. The pollution controlling ability of government has no influence on green economy in the east. Both the pollution controlling ability of enterprise and human capital can affect green economic development significantly.Therefore, in order to promote the green economic development in the resource-based cities across the country, measures should be taken generally and specifically. On the whole, infrastructure should be strengthen for the free flow of factors, advanced technology should be introduced to promote domestic technological innovation, supervision mechanism should be improved shifting the duty from government to the public and the funds of education should be made full use of. According to different situations in different areas, more specific measures should be taken. For the east, the investment pace should be slowed down and accelerate the capital’s transfer to the inland, promoting the green economy in the middle and west. Meanwhile high-tech industry should be developed to absorb senior talents. For the middle, central city should be developed to play the role of radiation. For the west, raw material processing industry should be encouraged to diversify industry, gradually reducing the proportion of mining industry in GDP and stepping up to the green economy.
