Abstract The entropy method is used to calculate pollution comprehensive index reflecting provincial environmental pollution level. On this basis, the Malmquist productivity index is used to study the regional green total factor productivity (GTFP) in China, and the system generalized moment method is used to explore the influencing factors of GTFP. Firstly, the results show that the provinces with lower environmental pollution comprehensive index are mainly in the western and eastern regions, while the provinces with higher pollution comprehensive index are mainly distributed in the central inland areas. Secondly, GTFP shows an N-type upward trend, which is basically consistent with the trend of total factor productivity. The overall GTFP in the east is on the rise, which is promoted by technical efficiency. The GTFP in the central and west has declined, and the main factor restricting their improvement is technological retrogression. The expansion of production scale in the east and west can contribute to the improvement of GTFP. The central region is at a stage where the scale of returns is not economic, and it is more important for promoting technological progress. Lastly, the industrial structure can significantly inhibit the increase of GTFP, however, the energy consumption structure, FDI and pollution control investment have a significant role in improving GTFP.

1 Introduction With the progress of industrialization in the world, the human society has made rapid development and created enormous material and spiritual wealth. When we accumulate social wealth, we have also caused multiple crises such as energy depletion, environmental pollution and ecological degradation worldwide. Especially in the late 20th century, global environmental problems were very serious such as global warming, soil desertification, freshwater crisis, forest degradation, sharp decline in biodiversity, and destruction of the marine environment. The global environmental problems continue to deteriorate, which greatly destroys the harmonious relationship between human and ecological environment. In order to resolve these crises and achieve coordinated development of economy, resources and environment, many countries have successively proposed * Yangjun Ren [email protected] 1

development models, which have set off a global boom in resource conservation and environmental protection. Obviously, human beings are gradually recognizing the painful environmental costs brought about by the traditional economic development model, therefore, it is imperative to effectively improve the ecologica
