Research on the Measurement and Spatial Spillover Effects of Green Total Factor Productivity in Western Regions

Abstract

Green total factor productivity emphasizes the progress of technology and the improvement of factor input efficiency. The western region is an important ecological barrier in China, and more attention should be paid to green development. Firstly, the paper selects the panel data of 12 provinces in western China from 2007 to 2020, and measures their green total factor productivity and its decomposition factors using the EBM model and GML index. Based on this, the paper selects control variables such as industrial structure, government behavior, economic development level, foreign investment and scientific research investment, and uses the spatial Durbin model to study the spillover effect of green total factor productivity in western China, it was found that the driving force of green total factor productivity in the western region to promote the economy mainly comes from the efficiency of green technology. Foreign investment has a positive effect on it, while government behavior is opposite to the level of economic development, and the industrial structure has a positive spillover effect on it, while the level of economic development is opposite. Therefore, suggestions have been put forward to improve the level of green technology, promote industrial structure upgrading, and focus on the quality of foreign investment introduction, in order to provide reference for the development of green total factor productivity in the western region.
