中国地理标志产品的区域差异分解及空间收敛性

Regional Difference Decomposition and Spatial Convergence of Geographical Indication Products in China

文章基于1996—2021年地理标志产品数量的地级市面板数据,剖析了中国地理标志产品的时空变化特征;同时运用Dagum基尼系数分解方法刻画了地理标志产品地区差异,并采用标准差与空间面板模型检验了σ收敛与β收敛。结果表明:①中国各城市地理标志产品核心区完成了由西北向东南的动态转移,并形成了密集聚集地带。②各城市总体差异呈“先升再降”的波动趋势;组间差异是总体差异的主要来源。③八大经济区中,仅大西北经济区存在σ收敛,全国及八大经济区存在显著的绝对β收敛与条件β收敛。各城市资源禀赋、地理位置、经济发展水平等情况各不相同,各外生性因素对地理标志产品发展的影响也不尽相同。

Based on the panel data of geographical indication(GI)products in 1996-2021 at the prefecture level,this article analyzes the spatiotemporal distribution characteristics of the GI products,uses the Dagum Gini coefficient decomposition method to characterize the regional differences and evolutionary trends of GI products,tests itsσ-convergence andβ-convergence by the means of the standard deviation and the spatial panel model.The results indicate that:1)The core areas of GI products in Chinese cities has completed the dynamic transfer from the northwest of China to the southeast of China,and has formed a dense gathering zone.2)The overall differences among cities show a fluctuating trend of"upward and subsequent downward movement."Inter-group differences represent a significant source of overall variation.3)Among the eight major economic zones,only the northwestern economic zone showsσ-convergence.There is significant absoluteβ-convergence and conditionalβ-convergence in China and eight economic regions.It is different in terms of resource endowment,economic development level,and other conditions in different city.The impact of exogenous factors on the development of GI products is also different.
