Abstract:Based on the incentive policy texts of 31 provinces and the policy demonstration effects, clear set qualitative comparative analysis (QCA) method was used to analyze the policy configuration of patent innovation-driven model of prefabricated buildings in China. The results show that the patent innovation-driven policy configuration of Prefabricated buildings in China can be summarized into two paradigms:One is the internal culture-driven policy configuration which takes the direct tax subsidy and the talent cultivation policy as the complementary core variables.This paradigm can significantly improve the patent innovation level in provinces with certain development foundation of prefabricated buildings. The other is external incentive-driven configuration. It takes the burden reduction of financing subjects and the policy support for excellence as complementary core variables, which can effectively promote the level of innovation development when the number of construction enterprises in more provinces and regions.
