江西省农业经济发展水平指标构建及影响因素研究

Research on the Index Construction and Influence Factors of Agricultural Economic Development Level in Jiangxi Province

为探究影响江西省农业经济发展水平的因素,使用粮食产量、有效灌溉面积、农用化肥施用折纯量、乡村人口、农业机械劳动力、农药使用量、农村用电量来测算影响因素。根据2011—2020年《江西统计年鉴》相关数据,采用主成分分析法和线性回归模型对江西省农业经济增长及对应的农业指标投入关系进行研究分析。结果表明,粮食产量、有效灌溉面积、农用化肥施用折纯量对农业经济发展有正向作用,乡村人口、农业机械劳动力、农药使用量、农村用电量对农业经济发展呈负向影响。农业经济发展水平受乡村人口因素影响最大,因此应保证农民耕地数量和质量,扩大有效灌溉面积,提高科学技术水平,优化人才政策。

In order to explore the factors affecting the development level of agricultural economy in Jiangxi Province.In this paper,grain yield,effective irrigation area,net amount of agricultural chemical fertilizer application,rural population,agricultural machinery labor force,pesticide use and rural power consumption are used to calculate the influencing factors.According to the relevant data of Jiangxi statistical yearbook from 2011 to 2020,the relationship between agricultural economic growth and corresponding agricultural index investment in Jiangxi Province is studied and analyzed by using principal component analysis and linear regression model.The results showed that grain yield,effective irrigation area and net application amount of agricultural chemical fertilizer had a positive effect on agricultural economic development,while rural population,agricultural machinery labor force,pesticide use and rural power consumption had a negative effect on agricultural economic development.The development level of agricultural economy is most affected by rural population factors.Based on this,some suggestions are put forward,such as ensuring the quantity and quality of farmers ’ cultivated land,expanding effective irrigation area,improving scientific and technological level,optimizing talent policy and so on.
