农村集体产权制度改革与县域城乡收入差距

基于 2010—2019年全国 1486个县域的面板数据，以农村集体产权制度改革试点这一外生政策为准自然实验，采用多时点双重差分模型考察农村集体产权制度改革对县域城乡收入差距的影响。结果表明，农村集体产权制度改革在提高农村居民收入水平的同时，对县域城乡收入差距也具有显著的收敛作用；在考虑模型适用性、遗漏变量、样本自选择等问题后，基于 PSM-DID模型等多种方法的稳健性检验均支持上述结论；农村集体产权制度改革对县域城乡收入差距的收敛效应在东部、融资环境较好以及财力水平较高的县域更为明显；机制分析发现，推动农村经济增长与加快城镇化进程，是农村集体产权制度改革缩小县域城乡收入差距的重要作用渠道。

Rural Collective Property Rights System Reform and County Urban-Rural Income Disparity

Based on panel data of 1,486 counties nationwide from 2010-2019, the impact of rural collective property rights system reform on the urban-rural income gap in counties is examined using a multi-temporal double difference model with a quasi-natural experiment based on the exogenous policy of rural collective property rights system reform pilot. The results show that, on a national scale, the reform of the rural collective property rights system also has a significant convergence effect on the urban-rural income gap in counties based on raising the income level of rural residents; the results further strengthen the above findings based on various methods of robustness testing such as the PSM-DID model, taking into account issues such as model applicability, omitted variables, and sample self-selection; the reform of the rural collective property rights system. The convergence effect on the urban-rural income gap in counties is more pronounced in the east, in counties with better financing environments and higher levels of financial resources; the mechanism analysis finds that promoting rural economic growth and accelerating the urbanization process are important channels through which the reform of the rural collective property rights system works to narrow the urban-rural income gap in counties.
