We study the impact of formal and informal institutions perceived and experienced by firms on their innovation using the 2012 World Bank Enterprise Survey data in China. We propose a framework to identify different innovator types of firms. Our analysis shows that (1) perceived constraints from the governmental system make firms more likely to be innovators than non-innovators; (2) perceived constraints from the legal system make firms more likely to be imitators than innovators; (3) lack of formal finance makes firms more likely to be non-innovators than innovators; (4) prevalence of bribery makes firms more likely to be non-innovators than innovators but less likely to be innovation pretenders than innovators. Our study enriches institutional theory and innovation research by establishing a framework that encompasses multiple dimensions of formal and informal institutions perceived and experienced by firms and the impacts of such perception and experience on firms’ propensity to become certain type of innovator.
