| 摘 要： | 系统考察东北地区耕地利用功能转型对粮食生产的影响,有助于从国家全局层面把握耕地与粮食之间的关系,从而为我国实现农业现代化和粮食安全高质量发展提供科学参考。本文基于2011—2020年全国省级面板数据,采用熵权法、双固定模型等估计方法,明晰东北地区耕地利用功能转型特征及其影响国家粮食安全的作用机制。结果表明：2011—2020年,我国粮食安全水平呈上升态势,东北地区耕地利用功能转型有效赋能全国粮食安全。在地区异质性研究中,辽宁省、黑龙江省耕地利用功能转型的粮食安全保障效应更加明显,吉林省作用渠道有待畅通。在维度异质性研究中,东北地区耕地利用功能转型主要通过促进粮食数量安全和粮食经济安全保障我国粮食安全,粮食生态质量保障效应不明显。据此,为了使东北地区耕地利用功能转型更好地促进国家粮食安全,从提供东北地区耕地利用与粮食生产经济补贴、因地制宜制定东北地区耕地利用功能转型策略、打造以生态质量为导向的“优质粮食工程”等方面提出建议。

| Abstract: | A systematic investigation of the impacts of the functional transformation of farmland utilization in northeast China on grain production is helpful to hold the relationship between farmland and grains from the national level to provide scientific reference for the realization of agricultural modernization, grain security, and high-quality development in China. Based on a provincial panel data from 2011 to 2020, this paper analyzed the functional transformation characteristics of farmland utilization in northeast China and its function mechanism affecting national grain security by the entropy weight method and the double fixed model. Results show that: China"s grain security level was on the rise from 2011 to 2020, and the transformation of farmland utilization function in northeast China effectively enabled the national grain security. In the regional heterogeneity study, the grain security guarantee effects of farmland utilization functional transformation in Liaoning and Heilongjiang Provinces were more obvious, but the function channel of Jilin Province needed to be unblocked. In the dimensional heterogeneity study, the farmland utilization functional transformation in northeast China mainly guaranteed China"s grain security by promoting grain quantity security and grain economic security, but the effect of grain ecological quality assurance was not obvious. Therefore, to make the northeast region farmland utilization functional transformation to better promote national grain security, this paper suggests: providing economic subsidies for farmland utilization and grain production in northeast China, formulating the strategy of farmland utilization functional transformation in northeast China according to local conditions, and building a "high-quality food project" oriented by ecological quality. |
