The results show the followings. China's grain production carbon emission intensity showed a trend of first increasing and then decreasing, and the technological progress of grain production showed an increasing trend; the technological progress of grain production was conducive to reducing the carbon emission intensity of grain production, and the technological progress of grain production reduced the carbon emission intensity of grain production by 0.38 t per unit; there wais obvious heterogeneity in the effect of technological progress of grain production on the carbon emission intensity of grain production, and the reduction effect was more significant in the eastern and central regions. Its reduction effect was more obvious in the east and central regions and the main grain producing areas; the mechanism of grain production technology progress to reduce the carbon emission intensity of grain production was to improve the efficiency of chemical fertilizer and pesticide application. For this reason, we should actively bring into play the carbon emission reduction function of technological progress in grain production, promote technological progress in grain production in accordance with local conditions, and focus on promotion of weight-loss and pesticide reduction techniques, so as to continuously improve the efficiency of fertilizer and pesticide application.,

articleAbstract=基于2001—2020年中国31个省份的面板数据，测算各省粮食生产碳排放强度，以DEA-Malmquist模型测算的粮食生产全要素生产率表征粮食生产技术进步，并运用双向固定效应模型分析了粮食生产技术进步对粮食生产碳排放强度的影响及作用机制。研究结果表明：中国粮食生产碳排放强度呈现先上升再降低的趋势，粮食生产技术进步呈现升高趋势；粮食生产技术进步有利于降低粮食生产碳排放强度，粮食生产技术进步1个单位，粮食生产碳排放强度降低0.38 t/万元；粮食生产技术进步对粮食生产碳排放强度存在明显的异质性，其削减作用在东、中部地区和粮食主产区更明显；粮食生产技术进步降低粮食生产碳排放强度的作用机制为提高化肥、农药施用效率。为此，要积极发挥粮食生产技术进步的碳减排功能，因地制宜推进粮食生产技术进步，重点推广减肥减药技术，不断提高化肥施用效率和农药施用效率。, authors=闫豪玮, 穆月英, authorsList=闫豪玮, 穆月英,
