摘要

本研究旨在反映数字经济发展中的灰色信息覆盖和复杂交互效应。因此，本文提出了一种基于灰色交互关系度的正态云矩阵（GIRD-NCM）模型的多属性决策方法。首先，将原始的信息覆盖灰度数转化为法线云矩阵，然后利用不同的信息原理提出一种新颖的法线云之间的闵科夫斯基距离。其次，根据 Choquet 模糊积分和灰色关系度建立了 GIRD-NCM 模型。最后，对 2013-2020 年中国数字经济发展进行动态综合评价。通过与现有三种评价模型的对比分析，验证了 GIRD-NCM 模型的实现性、可用性和可行性。实证结果表明，中国数字经济呈稳定增长趋势，年增长率为 7.87%，但地区发展差异明显。交互程度的变化对数字经济发展领先或中等水平省份的排名没有影响，但对数字经济发展水平较高和较低省份的排名分别产生了积极和消极的影响。

DYNAMIC MULTI-ATTRIBUTE EVALUATION OF DIGITAL ECONOMY DEVELOPMENT IN CHINA: A PERSPECTIVE FROM INTERACTION EFFECT

This study aims to reflect the grey information coverage and complex interactions effect in digital economy development. Therefore, a multi-attribute decision making method based on the grey interaction relational degree of the normal cloud matrix (GIRD-NCM) model is proposed. First, the original information coverage grey numbers are transformed into normal cloud matrixes, and then a novel Minkowski distance between normal clouds is proposed by using different information principles. Second, the GIRD-NCM model is established according to the Choquet fuzzy integral and grey relational degree. Finally, the dynamic comprehensive evaluation of digital economy development in China from 2013 to 2020 is conducted. The implementation, availability, and feasibility of the GIRD-NCM model are verified by comparative analysis with three existing evaluation models. The empirical findings reveal a stable growth trend in China’s digital economy, with an annual growth rate of 7.87%, however, there are notable regional development disparities. The change in interaction degree has no effect on the rankings of provinces that are in the lead or have a moderately high level of digital economy development, but has a positive and negative impact on the rankings of these provinces with high and low levels of digital economy development, respectively.
