本文以信息费用、交易费用为分析工具,从合约选择的视角,分析了水库移民合约的使用条款。由政府施加合约的使用条款,目的在于减低水库移民的交易费用。使用条款的形式,取决于现实世界存在的约束条件,包括移民群体实施的行为所施加给政府的局限。使用条款若能符合水库移民这一产权交换现象的约束条件,则水库移民的交易费用得到减低。 Based on the information cost and transaction cost, this article analyzes the terms and conditions of the contract of reservoir resettlement from the perspective of contract selection. The terms of the contract imposed by the government are intended to reduce the transaction costs of reservoir settlers. The form of terms of use depends on constraints in the real world, including those imposed on the government by immigrant groups. Terms of use if consistent with the reservoir resettlement of property rights exchange constraints, then the transaction costs of reservoir resettlers reduced.
