Abstract

Utilizing panel data (2013-2023) from Heilongjiang's 12 prefecture-level cities, this study established a comprehensive evaluation index system for a composite system (DE-AM). Methods including comprehensive evaluation, coupling coordination degree (CCD), spatial autocorrelation, and obstacle degree models were employed to analyze CCD, interaction effects, and influencing factors. Key findings are:1. Provincial AM and DE levels showed upward trends, with CCD improving annually. Most cities exhibited DE lag (optimizing), exceptHarbin.2. DE is the Granger cause of AM;AM's positive impact on DE was statistically insignificant.3. Major obstacle factors: Labor productivity, S&T expenditure, telecom business volume, granted invention patents. Key external factors: Economic development level, regional population size, transportation infrastructure level.
