Research on the factors influencing the development of green finance in Beijing, Tianjin and Hebei under the perspective of ecological environmental protection

In today's world, the contradiction between people and the ecological environment is becoming more and more acute. Green finance is an effective method to resolve the contradiction between economic growth and ecological environment pollution, which has been widely recognized by all countries. This paper analyzes the level of green financial development in the Beijing-Tianjin-Hebei region through an analytical model of green financial development influencing factors constructed by simulation, combined with ecological environmental protection, and identifies the main influencing factors affecting the level of green financial development in this region. In addition, the realization path proposed in this paper from the perspective of government-led green financial development is, firstly, to improve green finance-related standards, assessment system and green financial legal system. The second is to implement green financial regulation and improve the driving force of green policy and market integration. The research results show that the comprehensive measurement score of green finance development level in Beijing, Tianjin and Hebei region shows a steady increase between 2016 and 2020, among which the comprehensive measurement score of green finance development level in Beijing is as high as 72.13 in 2020, an increase of 17.32%. It provides theoretical guidance for the improvement of green financial public policies in Beijing, Tianjin and Hebei regions.
