摘要:

本研究旨在提出促进长江经济带第三产业绿色技术创新水平提升的建议,为推进经济带协同一体的高质量发展提供理论依据。基于Min-DS模型,测度2001—2018年第三产业绿色技术创新效率,并结合Dagum基尼系数和Kernel密度估计,揭示区域及其子地区绿色技术创新效率变化的时空差异特征、贡献率及动态演变规律。以长江经济带为例研究得知:在观察期内经济带第三产业绿色技术创新效率总体呈上升趋势,下游地区效率具有显著优势;但各省市效率变化趋势存在较大差异,效率强度区域的空间分布随时间改变;上中下游地区内及之间绿色技术创新效率的时空差异是经济带时空差异的主要来源。本研究系统分析了长江经济第三产业绿色技术创新效率的分布及演变特征,得到了其提升绿色技术创新水平的有效路径。

Abstract:

The purpose of this research is to put forward suggestions to improve the level of green technology innovation in the tertiary industry in the Yangtze River Economic Belt and provide a theoretical basis for promoting the synergistic high-quality development of the economic belt. Based on the Min-DS model, this paper measured the efficiency of green technology innovation in the tertiary industry from 2001 to 2018. The characteristics, sources and dynamic evolution of the spatial-temporal differences in the region and its sub-regions were revealed by integrating Dagum’s Gini coefficient with Kernel density estimation. Taking the Yangtze River Economic Belt as an example, it is found that: during the observation period, the efficiency of green technology innovation in the tertiary industry in the economic belt was generally on the rise, and the efficiency of downstream regions had significant advantages; however, there were large differences in the trend of efficiency change in various provinces, and the spatial distribution of efficiency intensity region changed with time; the spatial-temporal differences of the efficiency of green technology innovation in and between the upstream, midstream and downstream regions were major sources of the differences in the economic belt. This paper systematically analyzed the distribution and evolution characteristics of green technology innovation efficiency in the tertiary industry of the Yangtze River Economy Belt, and obtained an effective path to improve the level of green technology innovation.

Key words: the tertiary industry, green technology innovation efficiency, Min-DS model, spatial-temporal difference, the Yangtze River Economic Belt
