Research on the Impact of the “Three Changes” Reform in Guizhou Province on Farmers’ Income

中国农村集体产权制度改革，是乡村振兴中关于农村基本经营制度的重大改革，而贵州省“三变”改革更是中国农村集体产权制度改革的急先锋，但其对农村居民的收入影响如何仍需要验证。本文基于2015~2022年贵州省各市(州)面板数据，以“三变”改革这一外生政策为准自然实验，利用双重差分模型以及一系列稳健性检验考察“三变”改革对农户收入的影响，识别改革对农村居民收入影响的净效应。研究发现，“三变”改革能够提升农村居民家庭收入水平，可使试点地区农村居民可支配收入提升6.6%。最后为破解集体经济发展难题、拓宽农村增收渠道、加快农村发展步伐激活乡村振兴新动能。The reform of China’s rural collective property rights system is a major reform of the basic rural management system in rural revitalization, and the “three changes” reform in Guizhou Province is the vanguard of China’s rural collective property rights system reform. However, its impact on the income of rural residents still needs to be verified. This article is based on panel data from various cities (prefectures) in Guizhou Province from 2015 to 2022, using the exogenous policy of the “three changes” reform as a quasi natural experiment. It uses a difference in differences model and a series of robustness tests to examine the impact of the “three changes” reform on farmers’ income, and identifies the net effect of the reform on rural residents’ income. Research has found that the “three changes” reform can improve the income level of rural households, and can increase the disposable income of rural residents in pilot areas by 6.6%. Finally, in order to solve the problems of collective economic development, broaden channels for rural income increase, and accelerate the pace of rural development, we will activate new driving forces for rural revitalization.
