[1]我国粮食主产区作物种业创新效率的区域差异及动态演进

Regional differences and dynamic evolution of innovation efficiency of crop seed industry in major grain-producing areas of China

摘要:

文章基于Super-SBM模型和莫兰指数等空间相关性分析方法,对2013—2021年粮食主产区13个省份的种业创新效率进行测度分析并揭示其时空演变特征。研究发现,粮食主产区种业创新效率呈现显著的区域差异,总体区域差异在2015年之前以及2020年以后主要源自区域间差距,2015-2020年主要源自超变密度；种业创新效率存在较为明显的两极差异,高水平地区和低水平地区之间的发展差距在不断扩大；种业创新效率难以实现“跨级跃迁”,相邻省份对本地种业创新效率的提升具有显著影响。

Abstract:

Based on spatial correlation analysis methods such as Super-SBM model and Moran index, this paper measures and analyzes the innovation efficiency of seed industry in 13 provinces in major grain-producing areas from 2013 to 2021 and reveals its spatio-temporal evolution characteristics. The results showed that the innovation efficiency of seed industry in major grain producing areas showed significant regional differences. The overall regional differences before 2015 and after 2020 were mainly due to inter-regional disparities, and from 2015 to 2020 were mainly due to super-variable density. The innovation efficiency of seed industry has [2]obvious bipolar differences, and the development gap between high and low level regions is expanding. The innovation efficiency of seed industry is difficult to achieve "cross-level transition", and neighboring provinces have a significant impact on the improvement of the innovation efficiency of local seed industry.
