乡村振兴背景下河南省农业科技要素贡献率的时空演变研究

Spatiotemporal Evolution of Contribution Rate of Agricultural Science and Technology Elements in Henan Province under the Background of Rural Revitalization

以河南省为例,运用索罗余值法测算河南省农业生产中农业科技要素贡献率及其时空演变特征.结果表明:河南省农业科技要素对农业生产贡献率整体呈上升趋势,但市域差异大、南北分异格局特征显著,农业生产过程中科技要素应用的“不均衡不充分”特征突出;河南省农业物质费用投入对农业总产值的贡献率高于劳动力、耕地面积要素,农业发展主要依靠增加投资来增加产量,仍处于粗放型农业发展阶段.最后,从优化农业生产要素组合、强化农业产业技术体系建设、提升农业科技创新水平三个方面提出对策建议,提高农业生产中科技要素贡献率,以农业现代化助力河南省乡村振兴的实践进程.

Taking Henan province as an example,the contribution rate of agricultural science and technology elements,in agricultural production in Henan province was measured by Solow’s residual method and its temporal and spatial evolution characteristics were analyzed.The research shows that:the overall contribution rate of agricultural science and technology factors to agricultural production in Henan province shows an upward trend,but there is a big difference between cities and a significant north-south differentiation pattern.The characterizes of“imbalanced and insufficient”of science and technology elements application in the process of agricultural production is outstanding.The contribution rate of agricultural material cost input to agricultural output value in Henan province was higher than that of labor force and cultivated land area.The contribution rate of agricultural material cost input to the total agricultural output value in Henan province is higher than that of labor force and cultivated land area,which indicates that agricultural development mainly depends on increasing investment to increase output,and it is still in the stage of extensive agricultural economic growth.Finally,the countermeasures and suggestions are put forward from three aspects of optimizing the combination of agricultural production factors,strengthening the construction of agricultural industrial technology system,and enhancing the innovation level of agricultural science and technology,to improve the contribution rate of scientific and technological factors in agricultural production,and promote the practical process of rural revitalization through agricultural modernization.
