Abstract

Abstract: Based on A-shares listed micro data of companies manufacturing from 2016 to 2017, this study uses DEA-Tobit model to calculate the government investment in science and technology influence on the performance of enterprise investment in science and technology level, and considers the output of science and technology under the influence of negative externalities based on the provincial macro data of 30 provinces（cities, autonomous regions） in China from 2016 to 2017,and then uses improved unexpected SBM model to measure China’s 30 provinces（cities, autonomous regions） of investment in science and technology performance of the government and enterprises by eliminating the impact on enterprise investment in science and technology of government investment in science and technology endogenous. The results show that government investment in science and technology negatively regulates the relationship between enterprise investment in science and technology and its performance. The performance of government and market investment in science and technology is higher in the developed regions. The performance of enterprises in the eastern coastal areas with the highest level of economic and technological development is higher than that of the government. The performance of the government and the market in the central region with a weak level of economic and technological development is equal to that of the market. The western region government investment in science and technology performance is higher than the market. The environmental pollution caused by science and technology in the central region with weak economy is more than that in the eastern region with the best economic development and the western region with the weakest development, which is in line with the inverted “U”relationship between the level of science and technology development and environmental pollution.

Key words: externality, endogencity, science and technology investment performance, government and market, improved unexpected SBM model, tobit model
