Research on the Evaluation of Agricultural Productivity in Underdeveloped Areas under the Background of Rural Revitalization——Taking Chongqing City as an Example
The improvement of agricultural productivity in underdeveloped areas is of great significance to the achievement of rural revitalization.This paper used DEA-BCC model and DEA-Malmquist index to evaluate the agricultural productivity of Chongqing City and its 37 counties and further analyzed the influencing factors.The study showed that at the whole city level,the agricultural productivity of Chongqing City from 2016 to 2020 had an upward trend,but were in DEA invalid state in most years,mainly due to low scale efficiency.The total factor productivity of Chongqing City has been steadily increasing,with an average annual increase of 10.7％.At the county level,the agricultural productivity of Chongqing City was relatively high from 2016 to 2020,but there were obvious regional differences.The DEA effective counties were mainly in the metropolitan area.The total factor productivity from high to low were Northeast Chongqi ng town group＞Southeast Chongqing town group＞Metropolitan area.Among the influencing factors,machinery input per unit of cultivated land,fertilizer input per unit of cultivated land,effective irrigation land ratio,and government investment were promoting factors,while industrial structure and proportion of grain sowing area were restricting factors.Consequently,it was suggested to implement the strategy of agricultural production modernization and regionalization.
