Impact mechanism of land resource allocation on integrated urban-rural development by ZHAO Wei, ZHU Peixin

“…[Results] (1) Theoretically, a unified market-based urban-rural land allocation system can bring about an increase in social welfare compared with a divided state, while the quasi-public goods attribute of land and the limited rationality of the government dictate that the allocation of land resources under the orientation of integrated urban-rural development should be between a “responsive government” and an “effective market”. (2) The government’s control behavior, characterized by tax policy, has a significant positive impact on the level of integrated urban-rural development, but the impact of industrial policy is not significant, and both the marketization of urban land and the marketization of agricultural land significantly contributed to the improvement of the level of integrated urban-rural development during the study period. (3) The mediation effects of marketization of agricultural land and urban land were 19.29% and 12.26% respectively in the path of tax policy affecting the level of integrated urban-rural development; the mediation effect of land marketization between industrial policy and integrated urban-rural development was not significant. …”
