Study on the Coupled and Coordinated Development of Climate Investment and Financing and Green Finance of China

The growth of climate investment and financing highlights the growing global focus on climate change. In China, fostering the coordinated development of climate investment and financing and green finance is a crucial step toward accomplishing sustainable development objectives and addressing climate challenges effectively. By constructing the indicator system of climate investment and financing and green finance, and using the entropy method and the coupled coordination model, we comprehensively explored the development level and the coupling coordination relationship between climate investment and financing and green finance in 30 provinces in China during the period of 2013–2022. The findings of the research indicate that the development of climate investment and financing and green finance in China as a whole shows a growth trend, but the development of climate investment and financing remains relatively underdeveloped, and noticeable variations can be observed among regions. In respect to the level of coupling coordination, the overall coordination level of each province has not yet attained the desired level of optimality, and despite the yearly increase in the coordination degree at the national level, it is still in the state of mild dislocation. The eastern coastal region has the highest level of coupling coordination and is in the stage of verging on dislocation. And the great northwestern region has the lowest level of coordination and is in the stage of moderate dislocation. These findings provide an important reference for the formulation and execution of climate investment and financing and green finance policies in China.
