城市数字治理评价体系构建与时空演变分析

Evaluation System Construction and Spatial-Temporal Evolution Analysis of Urban Digital Governance

摘要: 近年来，数字技术作为新时代发展变革的重要动力，已然成为国家和地方政府推进治理体系和治理能力现代化的有力抓手。本文基于数字基础、数字政务、数字经济和数字民生4个维度构建城市数字治理水平评价指标体系，运用组合赋权和GRA-TOPSIS法测度2013~2022年中国244个城市的数字治理水平。将我国划分为八大综合经济区，从时间和空间维度剖析城市数字治理水平的异质性与动态演变特征。研究发现，我国城市数字治理水平总体呈上升趋势，东部沿海地区水平明显优于其他地区，北部沿海地区次之，东北地区发展较弱；其次，城市数字治理水平存在显著的区域差异，且区域间差异大于区域内差异；此外，城际数字治理水平之间存在空间正相关性，空间溢出效应短期内为负，周边城市数字治理水平提升可能会在短期内对本市造成“虹吸效应”。

Abstract: In recent years, digital technology, as an important driving force for development and change in the new era, has become a powerful starting point for national and local governments to promote the modernization of governance system and governance capacity. Based on the four dimensions of digital foundation, digital government, digital economy and digital people’s livelihood, this paper constructs the evaluation index system of digital governance level in China, and measures the digital governance level of 244 cities in China from 2013 to 2022 by using combination weighting and GRA-TOPSIS method. China is divided into eight comprehensive economic zones, and the heterogeneity and dynamic evolution characteristics of digital governance level in China are analyzed from the time and space dimensions. It is found that the level of digital governance in China is generally on the rise, and the level in the eastern coastal areas is obviously better than that in other regions, followed by the northern coastal areas, and the development in the northeast is weak; secondly, there are significant regional differences in the level of digital governance in China, and the regional differences are greater than the regional differences. In addition, there is a positive spatial correlation between inter-city digital governance levels, and the spatial spillover effect is negative in the short term. The improvement of digital governance level in surrounding cities may cause a “siphon effect” on this city in the short term.
