摘　　要：对皖江区域农业科技进步贡献率和各要素贡献率进行测算,并进一步研究其与当地农业经济发展的时空演变特征及差异。结果表明:从时间分布来看,农业科技进步贡献率整体表现为下降趋势,物质要素在农业生产过程中贡献份额较大,劳动力以及耕地要素投入限制了农业经济的发展;从地区分布来看,各地区农业科技进步贡献率存在明显的差异;多数地区物质消耗投入量仍是农业经济发展的主要驱动力。基于此,从资源优势利用、降低物质消耗以及培养科技人才等方面提出建议。This paper calculates the contribution rate of agricultural science and technology progress and the contribution rate of each factor in Wanjiang region,and further studies its space-time evolution characteristics and differences with the local agricultural economic development.The results are that the contribution rate of agricultural scientific and technological progress shows a decreasing trend in the whole time distribution,and the contribution of material factors in agricultural production is larger,the input of labor force and cultivated land restricts the development of agricultural economy,and the contribution rates of agricultural scientific and technological progress are obviously different in different regions In most areas,the input of material consumption is still the main driving force of agricultural economic development.Based on this,the paper puts forward some suggestions on the utilization of resource superiority,the reduction of material consumption,and the training of scientific and technological talents.
