| 摘 要： | 山西省境内的吕梁、太行两大集中连片特困区是国家扶贫攻坚的主战场。本研究以该片区所辖4市21个国家级贫困县作为研究对象,从山西省统计局统计年鉴及国务院扶贫办获取研究区内2008—2018年共11年农业经济数据,采用主成分分析法对区域内的农业经济发展状况进行评价,旨在探讨山西集中连片特困区农业经济发展状况的时空分布特征及其与贫困之间的关系。结果表明：两大片区的农业经济发展水平具有地域差异性,随着时间推移,农业经济发展有所好转,但农民在农业生产过程中大量使用落后的农业机械削减了农民的生产积极性,从而导致农业总产值降低,在农业种植中施用过多化肥造成土壤贫瘠、土壤质量下降,引起农作物产量减少,进一步导致贫困加重。因此,在集中连片特困区进行精准脱贫时,要“依地施策、依时施策”,改变该区传统落后的农业生产方式,走绿色、包容、可持续的农业经济发展道路。

| Abstract: | Lvliang and Taihang, two concentrated and contiguous poverty-stricken areas in Shanxi Province, are the main targets for poverty alleviation of China. In this paper, 21 state-level special poverty-stricken counties in 4 cities of these areas were taken as the research objects. The agricultural economic data of the study areas from 2008 to 2018 were obtained from the Statistical Yearbook of Shanxi Provincial Bureau of Statistics and the Poverty Alleviation Office of the State Council. The principal component analysis method was used to evaluate the agricultural economic development, in order to explore the spatial and temporal distribution characteristics of agricultural economic development and their relationship with poverty in concentrated and contiguous poverty-stricken areas in Shanxi. The results show that there are regional differences in the agricultural economic development level between Lvliang and Taihang, and the agricultural economic development has been improved with the passage of time. However, farmers’ extensive use of backward agricultural machinery in agricultural production has reduced their enthusiasm for production, resulting in a decrease in the total agricultural output value. The application of excessive chemical fertilizer in agricultural planting has led to poor soil quality and crop yield decrease, and further aggravated poverty. Therefore, when targeted poverty alleviation is carried out in concentrated and contiguous poverty-stricken areas, it is necessary to “implement policies according to local conditions and time”, change the traditional backward agricultural production mode in these areas, and take a green, inclusive and sustainable agricultural economic development road. |
