美国大都市区治理中的地方政府自愿合作：何以兴起？何以持续？
The Voluntary Cooperation of Local Governments in the Governance of American Metropolitan Areas： How Dose It Occur？ How to Continue？

摘要 近年来，随着经济社会的发展，我国城镇化进程加速推进，城市规模不断扩大，城镇化水平持续提高，城市群的聚集效应凸显，区域化发展成为趋势。城市群内包含着层级不一、规模各异的城市政府，如何以有效的制度安排跨越行政边界最大程度地整合区域资源并连结区域内行动者，是区域治理面临的一大挑战。美国是高度城市化的国家，拥有世界级的城市群，在大都市区治理方面积累了充分的实践经验，形成了有效的制度安排。在地方自治的特殊政治背景下，美国地方政府通过政府间协议和组建区域自组织等形成了行之有效的府际自愿合作机制，以一系列制度安排降低了合作过程中面临的交易成本和交易风险问题，促进了合作关系的稳定持续，从而实现了对大都市区的有效治理。
Abstract：In recent years， with the development of economy and society， the process of urbanization in our country has been accelerating， the scale of cities has continued to expand， and the level of urbanization has continued to increase. The agglomeration effect of urban agglomerations has become prominent， and regional development has become a trend. How to effectively integrate regional resources across administrative boundaries and connect actors in a region is a major challenge for regional governance. The United States is a highly urbanized country with world-class urban agglomerations. It has accumulated sufficient practical experience in the governance of metropolitan areas and has formed effective institutional arrangements. Under the special political background of “home-rule”， the US local governments have formed an effective inter-government voluntary cooperation mechanism through intergovernmental agreements and the formation of regional self-organization. Through a series of institutional arrangements， the transaction costs and transaction risks faced in the cooperation process have been reduced， and the stable and continuous cooperation has been promoted， thereby realizing effective governance of metropolitan areas.
