The coupling effect between economic development and the urban ecological environment in Shanghai port

With the rapid development of ports in the world today, the ecological environment pollution of port cities is becoming more and more serious. How to coordinate the port industry and the urban environment is an urgent problem to be solved. This article proposes a system to evaluate the coordination between port industry chain development and the urban ecological environment by taking Shanghai Port as an example. The Principal Component Analysis (PCA) method was applied to calculate the weights of various indexes, then the Coupling Coordination Degree Model (CCDM) was adopted to systematically study the coordination relationship between port industry development and the urban ecological environment. Our research finds the coupling coordination degree between Shanghai Port's economic development and the urban ecological environment shows an overall upward trend, changing from severely misaligned in 2000 (0.125) to barely coordinated in 2019 (0.691). Shanghai has achieved some results in constructing the ecological environment and green port, but there is still much room for improvement. Shanghai port needs to strengthen container transportation, enhance energy conservation and emission reduction, and vigorously promote the development of a green port. This study will provide a basis and reference for relevant institutions, government departments, and policymakers to formulate scientific and effective green port industry chain development strategies.

This study proposes a system to evaluate the coordination between port industry chain development and the urban ecological environment using Shanghai Port as an example. The Principal Component Analysis (PCA) method and the Coupling Coordination Degree Model (CCDM) were applied to analyze the relationship between port industry development and the urban ecological environment. The research finds that the coupling coordination degree between Shanghai Port's economic development and the urban ecological environment is overall improving, but there is still room for improvement.
