Replication package — Plural pathways of adaptation: a typology of Chinese listed firms' responses to the 2021 patent reform

This repository contains the data and code required to reproduce the empirical results of the manuscript, which examines the heterogeneous firm-level responses of 1,256 Chinese Main Board listed firms to the 27 January 2021 patent reform (withdrawal of filing-stage subsidies). The analysis documents three stylized facts: (i) an aggregate post-shock slowdown of −0.33 pp masking a sharp invention/utility model divergence (+4.28 pp / −7.55 pp); (ii) a nine-profile hierarchical clustering on the 50 most active filers; (iii) a cross-sectional test rejecting digitalization as a general resilience mechanism. The package permits exact replication of all tables and figures in the manuscript and online supplement.本仓库包含复现该学术论文实证结果所需的全部数据与代码，该研究考察了2021年1月27日专利改革（撤销申请阶段补贴政策）对1256家中国主板上市公司的异质性企业层面响应。本分析揭示了三项典型事实：(i) 政策冲击后整体专利申请增速放缓0.33个百分点，但该宏观表现掩盖了发明专利与实用新型专利间的显著分化——发明专利申请增速提升4.28个百分点，实用新型专利申请增速下降7.55个百分点；(ii) 对申请活跃度排名前50的企业开展了九类分层聚类分析；(iii) 横截面检验结果拒绝了数字化可作为通用韧性机制的假说。 本工具包可精准复现该论文及在线补充材料中的全部表格与图表。
