Measurement of the Integrated Development Level of Industrial Chain and Innovation Chain in Guangxi under the Background of High-Quality Development

The synergistic advancement of industrial and innovation ecosystems plays a crucial role in bolstering regional economic competitiveness and fostering sustainable growth, which contributes to achieving superior development outcomes. This research examines Guangxi's development trajectory during the 2013-2022 period by establishing a comprehensive assessment framework for chain integration. The methodology incorporates three principal analytical tools: the entropy weighting approach for objective measurement, coupled system modeling for interaction evaluation, and coordination degree assessment for developmental alignment. Furthermore, constraint factor analysis identifies key impediments to integration. Empirical findings demonstrate that while Guangxi's dual-chain convergence exhibits progressive improvement, the current integration maturity remains at an initial stage. Diagnostic results highlight several primary constraining elements, including regional technology diffusion capacity, innovation output commercialization efficiency, spatial concentration of manufacturing enterprises, industry-academia-research partnership intensity, and cluster-based economic productivity. These evidence-based insights offer valuable theoretical foundations and practical guidance for optimizing chain integration strategies in regional development contexts.
