生产率视角下碳排放对粮食经济增长的影响因素研究

Research on Influencing Factors of Carbon Emission on Grain Economic Growth from Perspective of Productivity

从生产率的视角,以H省为研究对象,采用Tobit模型,就碳排放对粮食经济增长的影响因素进行了研究,结果显示:H省的粮食碳排放效率与化肥施用强度、产业结构、人均耕地面积呈十分明显的负相关,与受教育人口比例呈十分明显的正相关;H省西部区域的粮食碳排放效率与化肥施用强度呈极明显的负相关,与产业结构呈十分明显的正相关;在H省中部区域,粮食碳排放效率与化肥施用强度、产业结构呈明显的负相关,与单位面积机械总动力、受教育人口比例呈明显的正相关;在H省东部区域,粮食碳排放效率与人均耕地面积呈明显的负相关,与受教育人口比例呈明显的正相关。

Based on the perspective of productivity, the influencing factors of carbon emission on grain economic growth in H Province were studied by Tobit model. The results show that the efficiency of grain carbon emission in H Province showed a significant negative correlation with fertilizer application intensity, industrial structure and per capita cultivated land area. There is a significant positive correlation between the proportion of educated population and the efficiency of grain carbon emission.The regional level analysis shows that there is a significant negative correlation between chemical fertilizer application intensity and grain carbon emission efficiency in the western region of H Province, and a significant positive correlation between industrial structure and it. In the central region of H Province, grain carbon emission efficiency is negatively correlated with chemical fertilizer application intensity and industrial structure, and positively correlated with total mechanical power per unit area and the proportion of educated population. There is a significant negative correlation between the per capita cultivated land area and the carbon emission efficiency in the eastern region, and a significant positive correlation between the proportion of the educated population and it.
