Abstract
Green technology innovation is an effective driving force to achieve the optimization and upgrading of industrial structure. Environmental regulations principally behave in guiding green technology innovation activities. Based on the Super-Sbm-Dea efficiency model with undesirable output, this paper estimates the provincial-level efficiency of green industrial technology innovation (Gtie) in China from the aspects of technology development, technology transformation and industrial innovation value chain (IVC) from 2005 to 2015, and analyzes its dynamic trend with kernel density function. The conclusions are as follows: 1) Gtie is low and on the rise generally, and tends to decrease in the stages of technology development, achievement transformation and industrialization; in the stage of technology development, the gap between the eastern region and other regions of China tends to increase, while Gtie is on the contrary in the other stages. 2) Gtie spatial spillover is obvious. In the traditional panel model, the effects of command and public environmental regulations are obvious, while the roles of FDI and market regulations are opposite, and the impact of openness and economic development level is not significant. 3) Based on the analysis of Durbin model, market, public regulations and openness improve the efficiency directly. However, economic development level shows significant inhibition effect, while the role of the command regulations and FDI are not significant.
Highlights
Technological innovation plays an important role in the process of continuous adjustment and optimization of the economic structure
The green technology innovation refers to a series of innovative activities in the process of production, operation and sales to reduce pollution emissions, energy consumption and enhance environmental competitiveness
This paper applies Gtie to represent the efficiency of green technology innovation, the enterprise has the purpose to invest in the development of green technology, and to apply green environmental protection patent technology and green process fully
Summary
Technological innovation plays an important role in the process of continuous adjustment and optimization of the economic structure. Scholars analyze the role of environmental regulations from the perspective of manufacturing industry and different regions, and found that its effect on Gtie was inverted “U” (Liu & Yuan, 2018; Zang & Zhang, 2015). The role of environmental regulations on the green transformation of industry was studied from the perspective of the intermediary effect of green technology innovation (Peng & Li, 2016). These show that the command regulations have no non-linear impact on it, while the higher economic incentive and voluntary awareness by promoting green technology innovation, the high level of command regulations can promote industrial green transformation and upgrade successfully. Nese industrial Gtie. 4) Based on the spatial weight matrix of multi dimension, a Durbin model is used to integrate the interval correlation among various environmental regulations variables into the analysis of Gtie spillover effect, which may provide reference for selecting effective policies and multiple combinations of policies
