Digital innovation and green productivity gap
In response to the persistent challenge of low conversion efficiency and limited real-world impact of green technological progress, this study examines how digital innovation contributes to narrowing the green productivity gap, which reflects the inefficiency in transforming green technological achievements into realized productivity gains. Using panel data from 287 Chinese cities spanning 2009–2022, the analysis integrates mechanism testing, moderation analysis, and heterogeneity assessment to identify both the structural logic and boundary conditions through which digital innovation enhances green productivity transformation.

Introduction
The paper introduces the accelerating progress in digital technologies and its pivotal role in China's economic transformation. It highlights the significant growth in digital invention patents and the scale of the digital economy. Despite rapid digital transformation and green technological innovation, a persistent green productivity gap exists, indicating inefficiency in converting innovation into productivity. This study aims to understand how digital innovation can bridge this gap and promote sustainable economic performance.
Literature Review
A review of existing literature on digitalization and green development reveals that most studies examine these dimensions separately. Green technological innovation is recognized as a critical engine for sustainability, and the digital economy enhances regional capacity for green innovation through mechanisms like product/process innovation and resource allocation. While digital technologies improve green total factor productivity (GTFP), their effects vary, and there is a recognized misalignment between innovation efforts and productivity improvements, leading to the green productivity gap this study addresses.
Methodology
This section details the research design, model specification, and variable measurements. Employing a two-way fixed effects estimation framework on panel data for 287 Chinese cities (2009-2022), the study defines the green productivity gap (GPG) as the difference between green patent application growth and GTFP growth. Digital innovation is measured by digital invention patent proportion. Mediation models explore energy efficiency, industrial structure, and environmental regulation, while interaction terms test ownership structure and R&D investment as moderators. Robustness checks include alternative measurements, additional controls, alternative estimation methods, winsorization, and endogeneity tests using instrumental variables and a DID approach.
Empirical Results
Presents the baseline regression results, which consistently demonstrate a robust inverse association between digital innovation and the green productivity gap, significant at the 1% level. This supports Hypothesis H1: digital innovation effectively reduces inefficiencies. Robustness checks, including alternative variable measurements, additional controls (firm size, financial development), alternative estimation methods (System GMM, RE, GLS), winsorization, and endogeneity tests (2SLS, DID), confirm the stability and reliability of these findings, providing strong causal evidence.
Mechanisms & Moderation
The study reveals that digital innovation reduces the green productivity gap through enhanced energy efficiency, optimized industrial structures, and strengthened environmental regulation, with industrial structural optimization exhibiting the strongest mediating effect. Moreover, ownership structure and R&D investment significantly moderate this relationship. Private enterprises and strategically targeted R&D investment amplify the positive impact of digital innovation by improving flexibility, absorptive capacity, and innovation responsiveness, contrasting with the weaker efficacy found in rigid SOEs and inefficient R&D allocation.
Heterogeneity Analysis
Investigates regional disparities across city types, sizes, and geographical locations. The impact of digital innovation is notably stronger in inland regions and smaller cities, reflecting their greater unmet needs for digital integration and industrial upgrading. Conversely, coastal areas, large cities, and eastern regions exhibit diminished marginal impacts due to existing infrastructural and innovation ecosystem advantages, suggesting that further improvements depend more on systemic reforms rather than incremental technological inputs.
Conclusion & Policy Implications
Summarizes the findings: digital innovation significantly reduces the green productivity gap through enhanced energy efficiency, optimized industrial structure (strongest effect), and strengthened environmental regulation. Its impact is moderated by ownership structure (private firms more agile) and R&D investment (strategic targeting amplifies effects). Policy implications emphasize region-specific strategies: inland cities need digital infrastructure and institutional support; coastal cities require market-oriented R&D and deeper digital-green integration; and cross-regional coordination is essential to bridge spatial disparities.

Digital Economy Innovation Development Pilot Zones
The establishment of China's National Digital Economy Innovation Development Pilot Zones in October 2019 served as a quasi-natural experiment. Findings showed a significantly greater reduction in the green productivity gap in pilot cities compared to non-pilot cities, providing causal evidence for the positive impact of digital economy initiatives.
