农业生产性服务业发展对棉花全要素生产率的影响研究——基于中国棉花主产省市的经验证据

Study on the Influence of Agricultural Productive Service Development on Cotton Total Factor Productivity: Based on Empirical Evidence from Major Cotton Producing Provinces and Cities in China

该文基于15个棉花主产省市2003—2019年的面板数据,选择全局Malmquist指数法对各省市的棉花全要素生产率进行测算,进一步分析各省市农业生产性服务业的发展对棉花全要素生产率的影响情况,并检验人均植棉面积是否对农业生产性服务业发展与棉花全要素生产率产生的调节效应。研究表明,农业生产性服务业水平的提高可以显著促进棉花全要素生产的提高;人均植棉面积对农业生产性服务业与棉花全要素生产率间的关系起到调节作用,有着显著的正向影响。

Based on the panel data of 15 major cotton producing provinces and cities in China from 2003 to2019, this paper utilized the global Malmquist index method to calculate the total factor productivity of cotton in each province, and further analyzed the impact of the development of agricultural productive service on the total factor productivity of cotton in each province. The moderating effect of per capita cotton planting area on the relationship between agricultural productive service development and total factor productivity of cotton was also tested. The results show that the improvement of agricultural productive service can significantly improve the total factor production of cotton, per capita cotton planting area has a moderating effect on the relationship between agricultural productive service and total factor productivity of cotton, and per capita cotton planting area has a significant positive effect on the relationship between the two.
