Abstract

This paper develops and empirically tests a model linking firm productivity, digital technology adoption, and resource misallocation. Building on the Melitz (2003) framework, we propose a selection mechanism in which more productive firms are more likely to overcome fixed costs of digitalization, but market distortions can inhibit this process. Using administrative tax data for Chinese firms, we find that digital adoption is strongly increasing in firm productivity, consistent with the model’s selection predictions. Moreover, structural estimation using the Simulated Method of Moments (SMM) uncovers substantial heterogeneity in digital efficiency.
