The study finds that digitalization contributes to the improvement of regional economic development efficiency. Its economic impact primarily manifests in the transformation of traditional value creation models and the enhancement of marketization levels. The digital economy, by activating digital platforms, alleviates the problem of information asymmetry, thereby enhancing the standardization of market transactions and improving economic efficiency.
