Did Zhejiang counties historically classified as marginal-faction counties experience larger growth in the non-state (collective and private) share of industrial output from 1965 to 1978 than dominant-faction counties?

1. 1Preparação da base de dados
   ds_0032— | Variable Name | Description | | --- | --- | | countyid | Numeric identifier for a county in Zhejiang province, China. The same identifier links its observations across years. | | year | Calendar year. The file contains rows for 1952, 1957, 1965, 1978, and 1998. The nonsoe outcome is observed only in 1965, 1978, and 1998. | | nonsoe | Share of county industrial output produced by collective and private firms, on a 0–1 scale. Calculated as total industrial output minus state-owned industrial output, divided by total industrial output. | | mfc1978 | Indicator equal to 1 for a historically classified marginal-faction county in 1978, and 0 otherwise. This column combines the county's historical classification with the year being 1978; its zeros in other years do not mean that the historical classification changed. | | mfc1998 | Indicator equal to 1 for a historically classified marginal-faction county in 1998, and 0 otherwise. This column combines the same historical county classification with the year being 1998. | Dataset Context: This extract contains 61 counties in Zhejiang province, with 305 county-year rows. Industrial statistics were compiled from provincial statistical records. The non-state sector includes collective and private firms. Non-state industrial-output shares are unavailable in the file for 1952 and 1957; the numbers of counties with observed shares are 52 in 1965, 53 in 1978, and 61 in 1998. Reporting was disrupted during the Cultural Revolution, so the observations are benchmark years rather than a continuous annual series. Historical county classifications were constructed from organizational histories and county gazetteers. In Zhejiang, counties maintaining independent guerrilla forces during 1945–1948 were classified as marginal-faction counties, reflecting the subsequent marginalization of those local political elites within the provincial power structure. Other counties form the dominant-faction category. This historical classification is constant for a county; 1978 and 1998 in the two column names identify observation years, not dates when the classification was introduced. The county-level classification can be recovered from either column's value in its named year.
