Abstract
As an environmentally friendly and resource-management-oriented marine fishery production method,marine ranching has become an important practice for coastal cities in pursuit of green development by restoring the marine ecological environment and protecting fishery resources.Based on panel data from 53 coastal cities from 2010 to 2021,this paper uses the Super-efficiency SBM model and Global Malmquist-Luenberger index to measure the green total factor productivity(GTFP)of coastal cities as an indicator of their green development level.Additionally,a Difference-in-Differences model is constructed to empirically investigate the impact of national marine ranch demonstration zone policies on the green development of coastal cities.The study shows that national marine ranch demonstration zone policies can significantly promote the green development of coastal cities.Mediation effect analysis indicates that technological innovation and industrial structure upgrading are important channels through which national marine ranch demonstration z one policies promote the green development of coastal cities.Heterogeneity analysis reveals that the policies have a more pronounced effect on promoting green development in northern and central coastal cities,and the more national marine ranch demonstration zones there are,the more significant the promotion of green development in coastal cities.关键词
