Abstract

Using panel data for Chinese prefecture-level and above cities from 2010 to 2022, this paper treats the establishment of data trading platforms as a quasi-natural experiment and estimates a staggered difference-in-differences model. The reform does not significantly expand patent applications or alter patent-type structure, but it raises lagged invention-patent grant-conversion ratios. The result survives additional controls, endogeneity checks, parallel-trend and placebo tests, alternative definitions, wild-cluster bootstrap inference, and leave-one-province-out tests. Effects are stronger in cities with severe pre-policy conversion bottlenecks and are consistent with an information-matching channel proxied by digital finance. Data-factor marketization therefore appears to improve the conversion of higher-threshold applications into granted innovation outputs rather than simply increasing filing volume.
