As one of the five green finance reform and innovation demonstration district in China, the Guian New District between Guiyang and Anshun has played a key leading role in the development of green finance in southwest China. Since 2017, the green financial market in Guizhou province has achieved a leap-forward high-speed development. Based on this, this paper takes the idea of green development as the starting point, through in-depth analysis of the development status of green finance in Guizhou province under the policy control and guidance of the national and local governments,in order to find the limitations and obstacles in the development of green finance in Guian New District.In addition, at the end of this article, the author will further discuss the mechanism and path of green financial reform and innovation in Guizhou province from the aspects of perfecting policy guidance, optimizing organizational system, innovating products and services, etc. for effectively promoting the pace of green development in Guizhou province.展开更多
