- 摘要:
- 选取河南省18个地级市2012—2021年的农业生产相关的人力、土地、能源和产出数据，构建河南省农业生产效率测算体系，通过Un-Su-SBM模型测算农业生产效率，采用引力模型计算地级市之间的联系度，并将其二值化处理构建连通网络、计算网络特征；运用统计学理论，对投入要素进行方差分解，计算要素贡献率。结果表明：河南省各地级市的农业生产效率呈逐步上升趋势，年平均增长率3.15%，变异系数由初期0.087 2增长至中后期围绕0.114 1波动，区域差异程度增加。河南省社会网络结构相对稳定，大致形成三大城市圈；网络特征表现为密度增加，但效率下降，具有一定的冗余关系；通过方差分解，得出劳动力的贡献率最高，水资源利用效率不足。针对河南省农业的可持续发展，在缓解劳动力、网络结构以及资源利用不足等方面提出相关建议。
- Abstract:
- Human,land,energy and output data related to agricultural production of 18 prefecture-level cities in Henan Province from 2012 to 2021 were taken to construct the agricultural production efficiency measurement system in Henan Province,measured the agricultural production efficiency through the Un-Su-SBM model,calculate the degree of connectivity between the prefecture-level cities by adopting the gravitational model,and binarize it to construct a connectivity network,a computational network Characteristics.Statistical theory was applied to decompose the variance of input factors and calculate the factor contribution rate.The results showed that the agricultural productivity of prefecture-level cities in Henan Province showed a gradual upward trend,average annual growth rate of 3.15%.The coefficient of variation increasing from 0.087 2 in the early stage to fluctuating around 0.114 1 in the middle and late stages,and the degree of regional differences increasing.The social network structure in Henan Province was relatively stable,roughly forming three major urban circles;the network characteristics showed an increase in density but a decrease in efficiency,with a certain redundancy relationship;through the variance decomposition,it was concluded that the contribution of labor was the highest,and the use of water resources was not efficient enough.For the sustainable development of agriculture in Henan Province,relevant suggestions were made to alleviate the labor force,network structure and underutilization of resources.
