Abstract: Genetic resource is an important input factor in agricultural production. Usually contributions of production factors 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 this model to evaluate contributions of the factors to agricultural economic growth. For that end, Jiangsu Province was cited as a case for study. Calculation 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 resources. Therefore, Jiangsu Province should optimize its agricultural structure, improve its utilization of genetic resources, and increase its sci-tech input so as to promote its construction of its modern agriculture.
