Under the mode of export-oriented economy in coastal cities, there is a significant positive correlation between the development of green innovation economy and the development of export-oriented green innovation in coastal cities. In order to analyze the difference between the development and performance of export-oriented green innovation economy in coastal cities, this paper puts forward a correlation analysis model of green innovation economy development and performance under the coastal city export-oriented economic model based on Taylor index analysis and green innovation economy development effectiveness game. The Taier index mapping model is established to analyze the constraint index of the development of green innovation economy, and the financing constraint parameter model which affects the development of export-oriented green innovation in coastal cities is constructed. Taking the development efficiency and financing mode of green innovation economy as the explanatory variables, the development model of green innovation economy is constructed. The principal component game method is used to calculate the export-oriented green innovation development index of small and medium-sized coastal cities, to extract the index variables such as the growth rate of total assets, the operating profit margin and the physical property of enterprise assets for balanced game. By using the financial audit data and asset panel distribution data to analyze the Taylor index, the differences between the development and performance of the export-oriented green innovation economy in coastal cities can be quantitatively evaluated. The empirical analysis shows that the model has a good robustness in the development and performance evaluation of green innovation economy, and the effectiveness of decision-making on the development of export-oriented green innovation economy in coastal cities has been improved at different levels of significance. The decision-making effectiveness of export-oriented green innovation economy in coastal cities has a positive impact on regional economic development.
