Influencing Factors and Multiple Paths of Cultivated Land Planting Structure Evolution:A Fuzzy Set Qualitative Comparative Analysis Based on Cases of 30 Provinces
Based on the fuzzy set qualitative comparative analysis method,a case study of 30 provinces in China was conducted to analyze the influencing factors and multiple paths of the evolution of cultivated land planting structure.The results show that the"non-grain"or"grain-oriented"evolution of cultivated land is the result of the joint action of seven factors,including the scarcity of cultivated land,labor force going out to work,labor cost for growing grain,scale of farmland circulation,land cost for growing grain,agricultural mechanized operations and ag-ricultural socialized services.There are two"non-grain"paths driven by production factors and limited scale,and two sub-paths for large-scale"grain-oriented"induced by abundant cultivated land resources and increasing land costs.The rising land cost of grain planting is an important factor leading to"non-grain",and the modern agricul-tural production system is a complementary factor that can alleviate the adverse effects of grain planting land cost pressure on food cultivation.The impact of labor force going out for work is related to factors such as the scale of farmland circulation,agricultural mechanized operations,and agricultural socialized services,which jointly influ-ence the evolution of the cultivated land planting structure.
