中文摘要：

本文基于我国六大育种地区的面板数据，运用个体固定效应模型实证分析了我国公共科研部门育种创新与R＆D投入的问题。结果表明，公共科研部门育种科研经费R＆D投入对育种创新的作用在滞后期为2年后几乎消失．育种回报周期短；公共科研部门育种科研经费R＆D投入比例失调，基础研究对育种创新的消极性影响将显现，应用研究投入当期及试验发展投入滞后二期对育种创新产出见效快。本文还发现，以山东、河南、四川为代表的农业大省由于自身农业资源优势，育种科研经费R＆D投入对育种创新的产出作用不如江苏、吉林等经济发达地区；扩大育种经费R＆D投入的规模将对全国育种创新水平的提高有积极作用。

英文摘要：

Based on the panel data of Chinese six major breeding areas, this paper uses the fixed-effects model of individual moments to empirically analyze the breeding innovation and R＆D investment in Chinese public research sector. The results show that： the role of R＆D investment public breeding research R＆D playing in breeding innovation almost disappeared after a lag period of 2 years; Public breeding research R＆D input ratio is imbalance, and basic research had negative impact on breeding innovation, the current applying research and the lag of 2 experimental research was more significant to the breeding innovation. Due to their resources of agricultural, the functions of R＆D of Shandong, Henan, Sichuan are not as power as that of Jiangsu, Jilin developed province, and expanding the scale of R＆D will contribute to the overall breeding innovation.
