本研究探讨了最低工资对不同类型企业创新的异质效应。我们建立了一个基于研发的开放经济增长模型，得到了以下结果：提高最低工资降低了使用国内投入的企业的创新，但提高了进口外国投入的企业的创新。直观地看，当最低工资水平提高时，进口企业会用进口投入替代劳动力，从而产生技术溢出效应，增强企业的创新能力。我们使用中国城市层面的最低工资数据和企业层面的专利数据来检验这一结果。最后，我们发现，根据我们的理论，提高最低工资与进口企业的创新增加有关，而与非进口企业的创新减少有关。这个结果经受住了一系列稳健性检查。
This study explores the heterogeneous effects of minimum wage on innovation of different types of firms. We develop an open-economy R&D-based growth model and obtain the following result: raising the minimum wage reduces innovation of firms that use domestic inputs but increases innovation of firms that import foreign inputs. Intuitively, when the minimum wage increases, importing firms substitute labor with imported inputs, which have technology spillovers and enhance their innovation. We test this result using city-level data on minimum wages and firm-level patent data in China. Finally, we find that in accordance with our theory, raising the minimum wage is associated with more innovation by importing firms and less by non-importing firms. This result survives a battery of robustness checks.
