Impact of irrigation water rights trading on agricultural irrigation,production,and income:An empirical examination based on four provinces
A theoretical analysis framework was developed based on property rights theory and new institutional economics to analyze the changes before and after the implementation of the policy of irrigation water users'water rights transaction,and the impact of the reform was evaluated using the differential fixed-effect model.The framework was based on the water rights transaction data of irrigation water users in Gansu,Shanxi,Hebei,and Hunan provinces from 2019 to 2022.The study uses contractual water conservation,rated irrigation water consumption,and crop planting structure adjustment to empirically investigate whether the exchange of irrigation water rights can affect agricultural irrigated area,agricultural production,and farmers'income.The results show that with property rights precisely defined,water-saving contracts provide protection for water rights transaction,and rated water consumption promotes the improvement of water-saving effect and water-use efficiency from the perspective of demand management.Crop structure optimization and adjustment become crucial strategies for raising income and productivity when taking into account the costs and benefits associated with exchanging water rights.The findings demonstrate that through water rights trading,water-saving contract mechanism and water quota system,farmers are encouraged to improve irrigation water efficiency and optimize crop planting structure,which ensures efficient allocation of water resources,promotes the growth of total agricultural output and farmers'income,and contributes to sustainable agricultural development.
