Green Growth Efficiency Evaluation Based On Low Cabon Emissions

Research on green growth evaluation will measure the trend and level of national green growth development and is an important way of testing the results and process of green growth, correcting the deviation of development and predicting the future economic development model. It also helps to clarify the problems of economic development in countries with different development backgrounds, integrate economic and environmental resources and has important realistic significance to improve the efficiency of national green growth.The paper adopts three-stage DEA and convergence analysis methods and selects OECD countries, China, India, South Africa and Brazil as sample, the capital stock and labor as inputs, human development index as desirable output, carbon dioxide as undesirable output to measure and compare their efficiency of green growth during the year of 2000 to 2011. This research studies the following questions:(1) What is the green growth efficiency of major developed and developing countries in the world? What is level of Chinese? What is trend of the efficiency change? (2) What are influence factors of national green growth efficiency? How does affects the direction and degree? What are directions and how? (3) Does green growth efficiency of different countries converge? How to promote green growth efficiency in China?The results prove that:(1) Chinese Green growth efficiency ranks on the list in 38 countries. It not only has significant gaps with OECD developed countries, but also is lower than India, South Africa and Brazil. (2) Environmental regulation and technology innovation have a positive effect on the national green growth efficiency; FDI has a positive effect on the human development index and negative effect on reducing carbon dioxide emissions; Trade openness has no significant influence on human development index and negative effect on reducing carbon dioxide emissions. (3) Excluding the impact of exogenous environmental variables and random factors, Turkey, Israel, Britain, Chile and Brazil have achieved economies of scale during 2000-2011 except for a few years. South Africa and India are in the stage of scale increasing returns. The other countries are in the stage of scale diminishing returns, which means that technological innovation and management level are the key factors restricting green growth efficiency improvement of most countries. (4) There are five modes of national green growth efficiency trend:U-shaped, inverted U-shaped, fluctuation ascend, fluctuation declined and fluctuation with no trend. The paper analyzes the green growth practice of China, India, Germany, USA, Japan, Mexico, South Korea and production frontier countries. (5) Convergence test results show that countries with low efficiency can catch up with countries with high efficiency.On the way of green growth, countries with different political and economic background face different challenges and opportunities. At last, by analyzing empirical research results and combining Chinese actual conditions, we propose suggestions for policy makers in China from cultivation, strategic plan, governmental regulation, technical innovation and international cooperation.
