Systematic measurement and spatiotemporal evolution of agricultural versatility in China
ABSTRACT: In this study, the entropy weight method was used to measure the agricultural versatility of 30 provinces in China (excluding Tibet, Hong Kong, Macao, and Taiwan) from 2008 to 2019. In addition, the Theil index method and kernel density estimation were used to analyze the spatiotemporal ch...

| description | ABSTRACT: In this study, the entropy weight method was used to measure the agricultural versatility of 30 provinces in China (excluding Tibet, Hong Kong, Macao, and Taiwan) from 2008 to 2019. In addition, the Theil index method and kernel density estimation were used to analyze the spatiotemporal characteristics of the agricultural versatility in each province. The results show that the agricultural product supply and social security functions rapidly developed, but the economic development was weak. From 2008 to 2019, the total functional index of agriculture increased by 6.74%; the functional index of the agricultural product supply, social security, and ecological services increased by 12.72%, 5.53%, and 2.05%, respectively; and the functional index of economic development decreased by 1.32%. The development of agricultural multifunctions in China is regionally heterogeneous. Based on the Theil index method, the differences in the agricultural functions of the three regions are mainly due to intragroup differences. The contribution of intragroup differences of the eight economic regions is significantly lower than that of the three regions. However, intragroup differences dominate the agricultural product supply, economic development, and social security functions and intergroup differences control the ecological service function. The kernel density estimation curve shows that the overall agricultural functional evaluation index increased, among which the agricultural product supply function increased the most. |
