农村集体产权制度改革对县域经济的影响OACHSSCD

The reform of the rural collective property rights system is an important way to unleash the vitality of county economies and achieve common prosperity.Based on balanced panel data from 1,589 counties in China from 2013 to 2022,this study treats the pilot implementation of rural collective property rights system reform as a quasi-natural experiment and employs a Double Machine Learning(DML)model and a doubly robust instrumental variable(DR-IV)model to examine the impact of the reform on county-level economic growth and its underlying mechanisms.The results show that the re-form significantly promotes county economic growth,and this conclusion is supported by various robust-ness checks.Mechanism analysis indicates that the reform promotes county-level economic growth by fos-tering industrial agglomeration and upgrading the industrial structure.The effects of the reform exhibit clear heterogeneity.In terms of industrial structure,the reform has a significant positive effect on counties dominated by industry,while its effect on counties dominated by the service sector is not statistically sig-nificant and may even be negative in agricultural counties.In terms of the development foundation of dif-ferent regions,the effect is more pronounced in non-poverty counties during the period of the targeted poverty alleviation campaign,whereas the effect on counties stricken by poverty is not statistically signifi-cant.Therefore,it is necessary to continuously deepen the reform of the rural collective property rights system,strengthen the spatial adaptability of policies,and establish a differentiated implementation frame-work tailored to different types of counties.
