本文测度了2000-2022年中国28省份创新成果保护水平和生产性服务业内部结构升级程度,运用探索性空间分析方法对两者的空间关联性进行了检验,并从全国层面和分板块层面考察了创新成果保护对生产性服务业内部结构优化的空间影响.结果发现:(1)中国地区间创新成果保护和生产性服务业内部结构优化的集聚水平在研究期间内不断提高,且两者的空间演化存在较为明显的相似型和同步性;(2)创新成果保护水平的提升整体上有利于推动我国生产性服务业内部结构升级,但东、中、东北、西部四大板块省份创新成果保护对生产性服务业内部结构升级的作用程度存在较大差异,东中部地区的创新成果保护显著促进了生产性服务业内部结构优化,而西部和东北部地区的创新成果保护对生产性服务业内部结构优化的作用效果并不明显;(3)稳健性检验结果表明:上一年度的生产性服务业内部结构升级对创新成果保护水平的影响效应不明显,各地区生产性服务业内部结构升级异常值和直辖市因素对回归结果的干扰不显著;替换主要变量后创新成果保护水平变量的系数仍显著为正.研究结论补充和完善了创新成果保护与产业转型升级理论,为提升我国创新成果保护水平、促进生产性服务业内部结构升级提供了决策支持.
Protection of Innovative Achievements,Spatial Spillover,and Internal Structural Upgrading of the Productive Service Industry—Empirical Evidence from 28 Provinces in China
This study measured the level of innovation achievement protection and the degree of internal structural upgrading of the productive service industry in 28 provinces of China from 2000 to 2022.Exploratory spatial analy-sis methods were used to test the spatial correlation between the two variables,and the spatial impact of innovation achievement protection on the optimization of the internal structure of the productive service industry was examined at the national and sectoral levels.The results showed three main aspects of this system.(1)The agglomeration level of innovation achievement protection and internal structure optimization of the productive service industry between regions in China continued to increase during the sample period,and there was a clear similarity and synchronicity in the spatial evolution of the two variables.(2)The overall improvement in the protection level of in-novative achievements is conducive to promoting the internal structural upgrading of China's productive service industry.However,there are significant differences in the degree to which the protection of innovative achievements affects the internal structural upgrading of the productive service industry in the four major regions of the East,Central,Northeast,and West.The protection of innovative achievements in the East and Central regions signifi-cantly promotes the internal structural optimization of the productive service industry,while this effect is not signif-icant in the western and northeastern regions.(3)The results of the robustness test indicate that the impact of in-ternal structural upgrading of the productive service industry in the previous year on the level of innovation achievement protection is not significant.The interference from abnormal values of the internal structural upgrading of the productive service industry in various regions and the influence of municipalities directly under the central government on the regression results are not significant.After replacing the main variable,the coefficient of the innovation achievement protection level remained significantly positive.The conclusions of this study supplement and improve the theory of innovation achievement protection and industrial transformation and upgrading,providing decision-making support for improving the level of innovation achievement protection and promoting the internal structural upgrading of the productive service industries in China.
