摘要
采取回归分析及熵值法,结合耦合协调度模型和空间自相关Moran指数研究2010—2019年粤港澳大湾区对外贸易与科技进步耦合协调度及空间分布的演变规律。结果发现,虽然区域内对外贸易与科技进步耦合基础优越,但耦合协调度差异较大,科技进步水平滞后严重,整体良性耦合协调水平仍待提升;此外,二者耦合协调度的空间溢出效应明显,各阶层耦合协调度区间皆有上升迹象,间接反映科技进步于我国对外贸易发展水平的促进作用。
Using multivariate linear regression and entropy method,combined with coupling coordination degree model and spatial autocorrelation Moran's I index,the evolution law of coupling coordination degree and spatial distribution between Guangdong-Hong Kong-Macao Greater Bay Area foreign trade and Scientific-Technical progress in 2010-2019 was studied.The results show that although there is a coupling relationship between foreign trade and Scientific-Technical progress in all involved regions,the degree of coupling coordination is quite different;the level of Scientific-Technical progress lags behind seriously,and the overall benign coupling coordination level still needs to be improved.In addition,the spatial spillover effect of the coupling coordination degree between the two is extremely obvious,and the coupling coordination range of all levels shows signs of rising,which indirectly reflects the promoting effect of Scientific-Technical progress on the development level of China's foreign trade.
