基于数据包络分析的河北省区域创新效率评价

区域创新日渐成为经济学和现代区域科学领域的关注重点,运用因子分析与数据包络分析(DEA)模型测算河北省各县市创新效率,采用ESDA方法和克里金法探索创新水平的空间分异特征.结果表明:河北省创新效率有效区少、无效区多;各功能区调整幅度和侧重不同,环京津区、沿海区的综合效率和纯技术效率较好,冀中南区规模效率最佳,而冀西北区需做出全方位调整;创新效率存在集聚效应,热点区位于区域中部,冷点区位于西北部;河北省创新发展整体呈现多中心结构和核心—边缘结构,区位因素影响明显;环京津地区存在明显的中介效应.

Evaluation of Regional Innovation Efficiency in Hebei Province Based on Data Envelopment Analysis

Throughout the world, regional innovation has increasingly become the focus of attention in Economics and Modern Regional Science. Factor analysis method and DEA model are used to calculate the innovation efficiency of counties and cities in Hebei Province. ESDA method and Kriging method are used to explore the spatial differentiation characteristics of innovation level. The results show that Hebei Province has fewer effective areas for innovation efficiency and more ineffective areas; the range of innovation adjustment and the emphasis of each functional area are different. The comprehensive efficiency and pure technical efficiency of the areas that Surrounding Beijing and Tianjin are better, and the central and southern region has the best scale efficiency, while comprehensive adjustment should be made in Northwest Hebei Province; Innovation efficiency has agglomeration effect. The hot spot is located in the middle of the area, and the cold spot is located in the northwest; the overall innovation development of Hebei Province presents "multi-center" structure and core-edge structure, and the effect of location factor is obvious; There is a significant mediating effect around Beijing and Tianjin.
