Estimation On Green Total Factor Productivity And Analysis On Its Influential Factors Of China’s High-Tech Industry

China is facing many environmental problems due to inefficient use of natural resources, energy and the deteriorating state of the environment as the economy is rising in a rapid speed. It is generally believed that the high-tech industry is a kind of clean, high efficiency industrial series, which will not have malignant influence on the environment. This kind of misunderstanding leads to unilateral emphasis on output growth in high-tech industries, while ignoring the adverse impact on the environment. In this situation, more objective and scientific evaluation of the economic quality has attracted more scholars’ attention. GTFP(Green Total Factor Productivity, GTFP) which has taken energy consumption and environmental pollution into consideration can do better in measuring the quality of economic growth.In this paper,we use the Super-SBM model to measure the GTFP in High-Tech industry from 2000 to 2013. The result shows that the GTFP of high-tech industry in China is rising almost through all the period; however, the growth rate shows a fluctuating downward trend. The empirical test about GTFP’s influential factors of High-Tech industry shows that development level of high tech industry, science and technology innovation, environmental regulation and capital density have a significant impact on its green productivity. Nevertheless, "Pollution Haven Hypothesis" of FDI is not significant. The empirical results have been further confirmed in the enterprise case analysis.
