Study on the coupled coordination of financial ecological environment and economic growth in the Guangdong-Hong Kong-Macao Greater Bay Area

Based on the background of the economic construction of the Guangdong-Hong Kong-Macao Greater Bay Area in the new era, this paper selects the panel data of 11 cities from 2008 to 2020 to build a financial ecological environment index system and calculate the comprehensive evaluation index. The coupled coordination model and Moran’I index model are used to conduct quantitative research on the relationship between financial ecological environment and economic growth in the Guangdong-Hong Kong-Macao Greater Bay Area, comprehensively evaluate the financial ecological environment and economic growth status in the Guangdong-Hong Kong-Macao Greater Bay Area, and verify the two-way driving relationship between the two. Explore the regional differences and spatial agglomeration phenomenon in the relationship between financial ecological environment and economic growth from the two dimensions of time and space. Finally, it is concluded that the financial ecological environment in the Guangdong-Hong Kong-Macao Greater Bay Area varies significantly and geographically, and there is indeed a significant two-way promotion relationship between the financial ecological environment and the economic growth. The financial ecological environment will not only promote the economic growth of the region, but also have a spatial spillover effect on the surrounding areas.
