The industries in the Bohai rim region are intensive,and heavy industries in coastal provinces and cities are gathering.Land-based pollution has become one of the important factors for the marine environmental pollution in the Bohai Sea.In the aspect of the restoration of marine environmental pol-lution in the Bohai Sea,the cooperation of the local governments of the Bohai Sea is crucial for the con-trol of land-based pollution in the Bohai Sea.At present,the local governments in the Bohai rim have mainly problems such as inter-governmental coordinated governance motives and regional development differences,local government governance models and marine pollution attributes incompatibility,inter-governmental coordination concepts and local interests.In response to the above problems,the author proposes to cultivate the synergy awareness of the local governments of the Bohai rim,to improve the collaborative governance system,and to improve the coordinated governance mechanism from the per-spective of inter-provincial synergy and synergy mechanism with a view to achieving inter-governmental coordinated governance of land-based pollution in the Bohai rim.
