摘　　要：遗传资源是农业生产中重要的投入要素,通过将遗传资源投入纳入C-D生产函数模型,并对2001—2007年江苏省农业生产经济数据进行分析,计算江苏省遗传资源及其他生产要素对农业经济增长的贡献率。结果表明,江苏省农业经济增长主要依赖于动物遗传资源投入和科技进步。与固定资产和劳动力投入要素相比,遗传资源对农业经济增长的整体贡献明显,其中动物遗传资源的贡献高于植物遗传资源。因此,江苏省应优化农业结构,提高遗传资源利用率,加大科技投入,推进农业现代化建设。Genetic resource is an important input factor in agricultural production. Usually contributions of production fac？tors such as labor, fixed assets and technology to agricultural economic growth were calculated using the C？D production function model. While in this study, the concept of genetic resources was firstly introduced into the model to evaluate con？tributions of the factors to agricultural economic growth. For that end, Jiangsu Province was cited as a case for study. Cal？culation of contributions of genetic resources and other production factors to agricultural economic growth was done based on the data of agricultural production in Jiangsu Province from 2001 to 2007. Results show that agricultural economic growth in Jiangsu Province depends mainly on input of animal genetic resources and technological innovation. Although the contribution of technological innovation to agricultural economic growth in Jiangsu Province is high, while that of genetic resources is also significant. Meanwhile, the contribution of animal genetic resources is larger than that of plant genetic re？sources. Therefore, Jiangsu Province should optimize its agricultural structure, improve its utilization of genetic resources, and increase its sci？tech input so as to promote the construction of its modern agriculture.
