Digital platforms, as core infrastructures for online transactions and marketing interactions, have therefore come under increasing regulatory scrutiny amid tensions between technological progress and social stability. This study compiles a comprehensive Chinese Digital Platform Policy dataset consisting of national-level policy documents issued from 2000 through July 2025. We introduce a time-dimension topic clustering approach using density-based LDA algorithm to construct a policy corpus with reduced thematic overlap and develop a document-level policy intensity index by quantifying and aggregating the salience of domain-specific terms across documents. Validation exercises confirm the intensity measure strongly correlates with e-commerce transaction value and with digital innovation, with statistically significant lags consistent with policy implementation and firm adaptation. Beyond offering an empirically grounded metric, our analysis traces the dynamic co-evolution of regulation and technology adoption and identify composition effects\u2014the joint influences of enabling and disciplining policy elements\u2014on market outcomes. We argue that such effects also reconfigure the mix of marketing innovations. Collectively, the corpus and measurement framework provide a foundation for analyzing how regulatory innovation shapes the trajectory of marketing innovation and e-commerce development.<\/jats:p>","DOI":"10.3390\/jtaer21010002","type":"journal-article","created":{"date-parts":[[2025,12,24]],"date-time":"2025-12-24T09:58:34Z","timestamp":1766570314000},"page":"2","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Regulatory Innovation for Digital Platforms in the Data-Intelligence Era and Its Implications for E-Commerce"],"prefix":"10.3390","volume":"21","author":[{"given":"Danyang","family":"He","sequence":"first","affiliation":[{"name":"Sino-Danish College, University of Chinese Academy of Sciences, Beijing 100190, China"},{"name":"Sino-Danish Center for Education and Research, University of Chinese Academy of Sciences, Beijing 100190, China"},{"name":"Department of Organization, Copenhagen Business School, 2000 Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yilin","family":"Cai","sequence":"additional","affiliation":[{"name":"School of International Trade and Economics, University of International Business and Economics, Beijing 100029, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong","family":"Zhao","sequence":"additional","affiliation":[{"name":"Sino-Danish College, University of Chinese Academy of Sciences, Beijing 100190, China"},{"name":"Sino-Danish Center for Education and Research, University of Chinese Academy of Sciences, Beijing 100190, China"},{"name":"School of Economics and Management, University of Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6898-9351","authenticated-orcid":false,"given":"Zongshui","family":"Wang","sequence":"additional","affiliation":[{"name":"Business School, Beijing Information Science and Technology University, Beijing 100192, China"},{"name":"Institute of Mathematics and Systems Science, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Shen, B., Dong, C., and Ng, C.T.
