摘要构建粮食安全与种业创新指标评价体系,利用2001—2020年面板数据测算粮食安全发展指数,基于区域视角和省域视角检验种业创新对粮食安全的空间溢出效应及区域差异。结果表明:(1)2001—2020年粮食安全发展指数呈上升趋势,粮食主产区粮食安全指数最高,而产销平衡区粮食安全指数较低;(2)粮食安全发展水平地区间发展不平衡,空间上呈现从沿海到内陆递减的趋势,地区集聚效应明显;(3)种业创新环境和种业创新产出对粮食主产区、粮食主销区和产销平衡区三大功能区域的粮食安全均具有显著影响,种业创新投入的间接效应不同,市场化程度对粮食主销区粮食安全至关重要,粮食主产区和产销平衡区粮食安全较多依赖于农业技术条件和农业人力资本等基础性条件。 Constructing the evaluation system of food security and seed industry innovation indicators,based on the panel data from 2001 to 2020,the research calculated the food security development index,and tested the spatial spillover effect of seed industry innovation and the regional differences from the regional and provincial perspective.The results showed that:(1)The food security index showed an upward trend.The food security index in the main grain producing areas was slightly higher,while the food security index in the balanced production and marketing areas was relatively low;(2)The spatial distribution of food security development level showed a decreasing trend from coastal to inland,with obvious spatial agglomeration characteristics;(3)The innovation environment and innovation output had significant impacts on the three regions.The indirect effects of innovation input were different.The degree of marketization development had an important impact on the food security in the main food sales areas,while agricultural basic conditions such as agricultural technology conditions and agricultural human capital had a greater impact on the food security development in the main food production areas and the production and marketing areas.
