Data of China Family Tracking Survey (CFPS) from 2010 to 2018, CFPS data is the data organized and published by the China Social Science Survey Center of Peking University. CFPS data reflects the changes of China's society, economy and education by tracking and investigating the data of individuals, families and communities. CFPS has a total of 7 periods of open data. Due to the lack of relevant sector data in 2012 and 2020, five periods of data in 2010, 2011, 2014, 2016 and 2018 are selected as research samples. The data are processed as follows: 1. The family member questionnaire, the family economic questionnaire and the personal self-response questionnaire are combined horizontally. 2. The data of the five periods were vertically combined, and the individual household accounts in the household economic questionnaire were used to select rural household accounts as samples. 3. Select the central and western regions as the research samples, divide the experimental group and the control group according to the policy implementation pilot, and retain the relevant variables. 4. Remove missing values and outliers of relevant variables. Finally, 15,869 farmers were studied.
