数字经济增长动力与区域收入的空间分布规律

Spatial distribution of digital economic growth dynamics and regional income

为探究数字经济增长的动力构成、地域差异以及与区域收入之间的空间分布规律,本文以中国数字经济创新高地浙江省为样本,构建了数字经济增长动力要素指标体系,并首先提出了数字经济"增长动力指数"构想。借助Weaver-Thomas模型、灰色关联分析以及GIS分层设色法,从地级市层面对浙江省数字经济增长的主导动力构成进行空间可视化分析,并验证了其与区域收入的关联性。结果表明:(1)浙江省数字经济增长动力类型特征呈弱波动状态。(2)从整体空间格局来看,数字经济增长呈现以杭州和宁波为核心的"双核心"空间格局现象,产业供给动力主导型主要分布在浙西南地区;市场需求动力主导型、信息应用动力主导型及创新驱动动力主导型主要分布在浙西北地区。(3)数字经济"增长动力指数"与区域收入之间存在较强的关联性,较高的数字经济增长动力指数对应的地区收入也处于较高水平,反之亦然。数字经济主导动力结构的变化正在形成一种复杂多样的区域经济增长行为模式。

To explore the dynamic digital economy growth, regional differences, and the spatial distribution of regional income, this study takes Zhejiang Province, China’s digital economy innovation highland, as a research sample, constructs the index system of dynamic factors of digital economic growth, and proposes the concept of a Digital Economy Growth Driving Index(DEGDI). Using the Weaver-Thomas model, grey correlation analysis, and GIS hierarchical coloring method, the paper analyzes the dominant driving force of digital economic growth in Zhejiang at the city level and verifies its relevance with regional income.The research results show that:(1) The dynamic characteristics of digital economic growth in this province fluctuates in a small range.(2) From the spatial pattern, the digital economic growth presents a "double core" phenomenon, in which Hangzhou and Ningbo are the cores.The industry-supply leading type is mainly distributed in the southwest of Zhejiang;the marketdemand-driven, information-application-driven, and innovation-driven types are mainly found in the northwest part of the province.(3) There is a strong correlation between the DEGDI and regional income. The higher the DEGI, the higher the regional income, and vice versa. The change of the leading dynamics structure of the digital economy is forming a complex and diverse regional economic growth behavior mode.
