技术差距、资源分配与后发大国经济增长方式转换

经济增长的主要驱动要素的转变是经济增长方式转变的内核,而技术差距是影响经济资源配置格局和配置效率的关键变量。基于拓展的内生增长模型分析资源最优分配路径发现:经济增长方式随技术水平的提升从"生产性投资驱动"到"研发驱动"、从"模仿主导"到"创新主导"逐步转换。基于我国省级面板数据的经验分析表明:在不同技术水平的区域,生产性投资与研发投资、模仿与创新对经济增长和技术进步的效应不同。那么,我国作为一个后发大国在推进经济增长方式转变过程中也应根据与国际前沿的技术差距,合理配置生产性投资与研发投资、模仿投资与创新投资,并根据我国区域技术水平的差异性,"分层"推进经济增长方式的转变。

Technology Gap,Resource Allocation and Transformation of Growth Pattern of Large Lagging Country

The transformation of the main driving factors of economic growth is the essence of the transformation of economic growth mode,the technology gap is the key variable to affect the allocation pattern of economic resources and allocative efficiency.This paper,based on the expended endogenous growth model,demonstrated that the optimal allocation path of resources.It is shows that the mode of economic growth transfers from production-driven to R&D-driven,from imitation-dominated to innovation-dominated,along with the decrease of the technology gap.Empirical study based on China’s provincial panel data shows that production investment and R&D investment,imitation and innovation have different effects on economic growth and technological progress in regions with different technology level.Therefore,as a Large lagging country,China should allocate rationally productive investment and R&D investment,imitation investment and innovation investment according to technology gap during the transformation of growth pattern,and should promote differentially the transformation of the economic growth mode according to the technological level of China’s different regions.
