数字经济—制造业—物流业融合发展空间关联研究——以贵州与成渝地区双城经济圈为例

Study on the Spatial Correlation of Digital Economy-Manufacturing Industry-Logistics Integration Development——Take Guizhou and Chengdu-Chongqing Economic Circle as Examples

采用熵值法、耦合协调度模型、修正的引力模型和社会网络分析法测算贵州及成渝地区双城经济圈数字经济、制造业与物流业融合发展水平及空间关联网络结构演变特征。结果表明:贵州及成渝地区双城经济圈数字经济-制造业-物流业融合发展势态较好,空间关联关系进一步加强,但大多处于中低关联强度;贵阳、成都和重庆在网络中的影响力大幅领先,跨省融合发展合作较为松散,核心城市的带动作用发挥得不够充分。

The entropy value method,coupling coordination degree model,modified gravity model and social network analysis method were used to measure the level of integration development of digital economy,manufacturing industry and logistics industry in Guizhou and Chengdu-Chongqing economic circle and the evolution characteristics of spatial correlation network structure.The results show that:the status of digital economy-manufacturing-logistics integration development in Guizhou and Chengdu-Chongqing economic circle is good,and the spatial correlation relationship is further strengthened,but mostly at low to medium correlation intension;Guiyang,Chengdu and Chongqing are substantially ahead in the network,and the cross-provincial integration development and cooperation is looser,and the driving effect of core cities is not sufficient.
