产业政策与企业技术突破——基于企业微观行为视角

Abstract

Industrial policy is crucial for achieving national technological sovereignty and safeguarding economic security. Based on a micro-behavior perspective of firms, this paper analyzes firms' innovation "behavioral constraints" and constructs a heterogeneous innovation model with endogenized behavioral biases, revealing the deep micro-mechanisms that hinder firms' technological leaps and exploring how China's industrial policy facilitates firms' technological breakthroughs. The findings show that firms' technological breakthroughs involve an "innovation window" formed by two critical points: the shift from incremental improvement to breakthrough innovation, and the return from breakthrough innovation to a conservative strategy. China's industrial policy expands this innovation window through downside-protection and incentive-based nudges, thereby helping firms sustain exploration of technological breakthroughs. A quasi-natural experiment based on the strategy of boosting China's strength in manufacturing confirms this mechanism. The conclusions not only provide a firm-level behavioral analysis framework for understanding the success of China's industrial policy but also offer policy insights into how industrial policy can effectively alleviate firms' behavioral constraints and systematically guide and unleash firms' innovative potential through behavioral nudging.
