Abstract

Abstract: 【Objective】Study on rice production pattern evolution characteristics and the influence mechanisms in Jiangsu Province.【Methods】Based on the panel data of rice production in different City areas in Jiangsu Province from 2005 to 2020,using hot and cold spots,multiple regression,and mediating effect analysis methods,the rice production pattern evolution characteristics and the influence mechanisms in Jiangsu Province were analyzed.【Results】The rice production pattern in Jiangsu Province had obvious characteristics of “northward shift” and agglomeration.The rice sown area in the central region of Jiangsu slightly decreased,while the rice sown area in the northern region of Jiangsu had increasing trend. The impact coefficient of urbanization on rice sown area was -0.384. The improvement of urbanization level caused the decrease in rice planting area. Rice resource endowment,industrial upgrading,cultivated land resources,and rural agricultural labor force had impact coefficients of 0.051,1.755,0.884,and 0.749 respectively on rice sown area,and had positive promoting effects on rice sown area. Cultivated land resources had mediating effect on rice sown area,that is,in the process of urbanization,cultivated land resources determine the scale of rice sown area.【Conclusion】The rice production pattern in Jiangsu Province had obvious characteristics of “northward shift”. Urbanization had negative effects on the rice sown area,while rice resource endowment,industrial upgrading,cultivated land resources,and rural agricultural labor force had positive effects on rice sown area. Cultivated land resources had mediating effect on rice sown area.
