数字经济驱动中国制造转型升级研究

在数字经济发展的背景下，探究数字经济发展的时空格局和收敛性问题，对于促进地区协调发展具有重要的现实意义。文章基于选取的2011—2021年我国30个省份的面板数据，采用熵权法构建了中国数字经济综合指数，并利用核密度估计考察了中国数字经济的地区非均衡性及动态演化规律，同时采用变异系数法与空间计量模型检验了数字经济的收敛特性。研究发现：中国数字经济的发展呈现出以东部沿海省份为核心，中西部内陆省份为外围的“核心—边缘”结构，“数字鸿沟”特征明显；“H-H”集聚与“L-L”集聚构成了中国数字经济发展的主要格局，呈现出一定的极化特征，并且随着时间的推移极化特征有所减弱，非对称结构趋于缓解。计量结果显示：中国数字经济发展水平具有

Research on the Spatiotemporal Differentiation and Convergence of China's Digital Economy Development Level

In the context of the development of the digital economy, exploring the spatiotemporal pattern and convergence issues of digital economic development is of significant practical importance in promoting regional coordinated development. Based on panel data from 30 provinces in China from 2011 to 2021, the article used the entropy weight method to construct the comprehensive index of China's digital economy. It examined the regional unevenness and dynamic evolution patterns of China's digital economy using kernel density estimation, and tested the convergence characteristics of the digital economy using the coefficient of variation method and spatial econometric models. It is found that the development of China's digital economy exhibits a “core-periphery” structure with eastern coastal provinces as the core and central and western inland provinces as the periphery, showing clear characteristics of a “digital divide.” The main pattern of China's digital economic development consists of “H-H” agglomeration and “L-L” agglomeration, displaying a certain degree of polarization. Over time, this polarization has weakened, and the asymmetric structure is gradually easing. The econometric results reveal that the level of development of China's digital economy exhibits characteristics of δ-convergence, β-convergence, and club convergence, but with varying convergence speeds in different regions. Compared to the eastern region, the central and western regions show a significant “catch-up effect,” and the convergence speed demonstrates a “differentiation feature” among provinces. Therefore, it is recommended that the government follow a collaborative approach to understand the spatiotemporal evolution patterns of China's digital economy and optimize regional structures, aiming to achieve common development among regions.
