粤港澳大湾区经济效率及空间溢出研究

Researchon Economic Efficiency and Spatial Spillover in Guangdong-Hong Kong-Macao Greater Bay Area

从经济空间关联的角度出发,以粤港澳大湾区9个内地城市以及香港、澳门2个特别行政区为研究对象,以2009年-2017年9年间的空间面板数据为基础,从湾区内城市群的开放度、政府调控能力以及人力资本竞争力三个维度构建指标体系,运用DEA模型测算大湾区历年的经济效率,并采用空间误差模型研究大湾区经济效率的空间溢出效应。研究发现,大湾区香港、澳门2个特别行政区的经济效率显著高于其他9个内地城市,大湾区整体经济效率呈现稳步增长态势;同时,香港和澳门2个特别行政区属于"高-高"型空间关联,其余9个内地城市属于"低-低"型空间关联,大湾区内经济发展存在明显的空间差异性,进出口额、政府财政支出等指标对湾区经济发展有明显的促进作用。在此基础上,提出推进粤港澳大湾区融合发展的对策建议。

From the perspective of economic spatial correlation,taking nine cities in Guangdong,Hong Kong,Macao of theBay Area as research objects,and based on the spatial panel data from 2009 to 2017,this paper constructs an index system from three dimensions of urban openness,government regulatory capacity and human capital competitiveness in the Bay Area,and uses DEA model to measure the economic effectiveness of the Bay Area over the years.The spatial error model is used to study the spatial spillover effect of economic efficiency in the Great Bay Area. The study finds that the economic efficiency of Hong Kong and Macao Special Administrative Regions in the Bay Area is significantly higher than that of the other nine mainland cities,and the overall economic efficiency of the Bay Area shows a steady growth trend. At the same time,the two Special Administrative Regions in Hong Kong and Macao belong to the " high-high" type of spatial correlation,while the other nine inland cities belong to the " low-low" type of spatial correlation,and there is a significant spatial gap in the economic development of the Bay Area. Heterosexual,import and export volume,government financial expenditure and other indicators have a significant role in promoting economic development in the Bay Area. On this basis,the paper puts forward some countermeasures and suggestions to promote the integration and development of GHM-GBA.
