从产权社会学视角出发,公共产权的界定是一个社会过程,涉及政府、企业、民众等多个界定主体,受到国家层面的正式法律、科层体制的运行机制、民间社会的文化规范等多重制度逻辑的共同影响。面对政治风险和社会风险的双重压力,地方政府必须合理界定公共产权并有效治理产权占有带来的困境。有效治理的背后是场域内部各行动主体运用各种策略相互博弈的结果。在博弈过程中,面对与博弈者相关的治理权分配、治理实践以及成员权这三种权利而展开的博弈,积极磋商和行政变通等成为地方政府的基本策略,而彰显生存正义和公平原则则是民众的应对策略。本文以M江边上S镇村民的采砂行为体现出的公共产权占有为例,以公共产权界定的多重逻辑为分析框架,来呈现公共产权界定背后的多重机制和相互作用过程的复杂性,从而对地方政府的治理实践做出社会学的解释。 From the perspective of property sociology, the definition of public property is a social process involving multiple defined subjects such as government, enterprises and people. It is subject to multiple systems such as formal laws at the national level, operational mechanism of bureaucracy, and cultural norms of civil society The common influence of logic. Faced with the dual pressures of political risk and social risk, local governments must rationally define public property rights and effectively manage the predicament posed by property ownership. Behind the effective governance is the result of various game players interacting with each other in the field. In the course of the game, the gambling, active negotiation and administrative flexibility in the face of the distribution of the right of governance, the practice of governance and the rights of membership related to the players become the basic strategies of the local government, and demonstrate the principle of survival and justice and fairness It is the public’s response strategy. Taking the possession of public property embodied by the sand mining of village S on the riverfront as an example, this article uses the multiple logic defined by public property as the analysis framework to show the complexity of multiple mechanisms and interactions behind the definition of public property, Thus making a sociological explanation of the governance practices of local governments.
