数据要素对高质量发展的影响OACHSSCD

The digital economy has become a crucial engine for China's economic growth,and the role and status of the massive data it generates are increasingly prominent.Public data possesses dual attributes as both a governance factor and a production factor,with enormous social and economic value.Against this backdrop,a systematic analysis of the role of public data in fostering high-quality development not only closely aligns with China's current economic goals and social development priorities but also provides valuable references for the formulation and implementation of future national policies. Based on data from 278 prefecture-level cities and above in China from 2010 to 2021,this paper uses the opening of local urban public data platforms as a quasi-natural experiment to construct a multi-period difference-in-differences model and empirically analyze the impact of public data openness on high-quality development and its underlying mechanisms.The findings indicate that public data openness can promote high-quality development.This conclusion remains valid after addressing endogeneity concerns and conducting robustness tests.Mechanism analysis reveals that this positive effect operates mainly by increasing entrepreneurial activity,optimizing the business environment,and improving resource allocation.Heterogeneity analysis further confirms that the effects of public data openness are more pronounced in cities with lower proportions of the primary industry and more advanced digital infrastructure,as well as those located within the five major urban agglomerations.These conclusions offer clear policy implications.First,it is recommended to continuously advance the secure and orderly opening of public data,ensure consistent policy implementation,and fully unlock the potential of public data resources to yield data dividends for high-quality development.Second,local governments should leverage public data openness to achieve interdepartmental information connectivity and further expand channels for public-government engagement.Finally,it should enhance digital infrastructure and actively promote the deep integration of digital technologies with traditional industries,laying the foundation for public data to fulfill its role. The marginal contributions of this paper are threefold.First,moving beyond the broad category of data factors,this paper focuses specifically on the public data factor,providing new empirical evidence to understand and evaluate it and enriching the relevant research on high-quality development.Second,it further clarifies the pathways through which public data openness facilitates high-quality development,deepening the understanding of how public data value is realized.This offers richer inspiration for fully exploring and utilizing public data in the future.Third,from the perspective of urban differences,it explores the heterogeneous impact on high-quality development,offering concrete guidance for refining future policy design.
