Integrated development of new energy and green digital economy from the perspective of regional coordination

With the acceleration of green transformation and digitalization, the integrated development of the green digital economy and the new energy industry has become the core driving force for promoting regional coordination and high-quality development. Based on the macro perspective of integrated development, this paper constructs a multi-agent game model of the coordinated evolution of the green digital economy and the new energy industry. It systematically describes the mechanisms of interactive behavior among the government, enterprises, and platform entities, driven by resource allocation, technical collaboration, and policy incentives. The model simulation results reveal that policy incentive variables are prone to causing economic pressure or regional imbalance. Based on the analysis path and research, it is shown that when the PCI (Policy Coordination Index) is 0.9, the growth rate of digital economy output value is 8.4%, and the coordination promotion factor is 2.27. The average TSS (Technology Sharing Rate) of cities with technology-sharing mechanisms is 0.655; the average FFI (Factor flow index) of the technology-support optimization group is 0.713. Improving the effectiveness of policy linkage, promoting technology-sharing mechanisms, and optimizing the flow of factors between regions are key paths to achieving deep integration between the green digital economy and new energy industries. This paper provides methodological support for the theory of integrated development, a theoretical basis, and strategic inspiration for promoting regional coordination and for formulating green transformation policies.
