Abstract: Agricultural technological progress is the main reason for the growth of Chinas grain production capacity. In order to determine the types of technological progress of wheat, corn and rice at different stages, and analyze the dominant technological progress mode affecting grain production，based on the provincial panel data of wheat, corn and rice from 1999 to 2016, and the theory of technological progress, this study used the E-S model and C-D function to calculate the contribution rate of the three major grain technological progress, and made periodic discrimination of the technological progress mode to decompose the contribution rate of biochemical technology and mechanical technology to the grain technological progress. The results showed that the average annual technological progress rate of Chinas wheat, corn and early rice (on behalf of rice) from 1999 to 2016 were 0.67%, 0.19% and 0.06%, respectively. Based on the results of this study, it was found that the keys to solve the problem of grain at the present stage were to rely on improving breeding ability, fertilization, irrigation and other ways to improve land productivity, and to rely on continuous raising the level of mechanization to improve labor productivity, increase comprehensive grain productivity, standardize production cultivation process, give full play to the biochemistry class into technical efficiency, and improve food technological achievements conversion, etc..

摘要： 农业技术进步是我国粮食生产能力增长的主要原因，为确定不同阶段小麦、玉米、稻谷的技术进步类型，并分析影响粮食生产的主导技术进步模式，选取1999-2016年小麦、玉米、水稻各省面板数据，基于技术进步理论，利用E-S模型与C-D函数，计算三大主粮技术进步贡献率，并对技术进步模式进行阶段性的判别，分解生物化学型技术与机械技术对粮食技术进步的贡献比率。研究结果表明，1999-2016年间我国小麦、玉米、早稻（代表稻谷）生产年均技术进步速度分别为0.67％、0.19％、0.06%，小麦、玉米以机械型技术进步为主导，早稻以生化型技术进步为主导。基于研究结果，发现依靠提高育种能力、高效施肥灌溉等方式提高土地产出率，依靠持续提高机械化水平而提高劳动生产率，提升粮食综合产出率，规范生产栽培过程，充分发挥生物化学类投入技术效能，提高粮食技术成果转化率等是解决现阶段粮食问题的关键。
