Stock market,credit market,and heterogeneous innovations

The relative importance of credit market development and stock market development in boosting innovation remains a long-standing debate issue. In this study, we document how different types of financial markets development affect heterogeneous innovations. Using a broad sample across 42 developed and emerging economies and a generalized difference-in-differences identification strategy, we find that stock market development leads to significantly higher substantive innovation, especially in young and small firms, but has negative impact on incremental innovation. Conversely, credit market development promotes incremental innovation, especially in mature and large firms, but has negative impact on substantive innovation. Further analyses indicate that stronger shareholder protection enhances the positive impact of stock market on substantive innovation, while stronger creditor rights enhance the promoting effect of credit market on incremental innovation, and even turn the negative impact of credit market on substantive innovation into positive. Our paper provides new insights into the heterogeneous effects of credit market and equity markets on the real economy.     

环境规制约束下FDI对中国科技创新与经济高质量发展的影响——基于中介效应与门槛效应的机制检验

基于2003—2019年中国内地30个省份面板数据，运用中介效应、门槛效应模型实证检验FDI对我国技术创新与经济高质量发展的影响，并进行机制分析。研究发现：第一，在环境规制约束下，FDI技术溢出效应显著，FDI能够促进我国经济高质发展，现阶段环境规制具有“创新补偿”效应；FDI与环境规制的交互项能够显著促进经济高质量发展，环境规制对FDI发挥一定的正向筛选作用。第二，在考虑内生性后，FDI、环境规制及其交互项对经济高质量发展影响的核心结论依然成立，并且存在区域异质性。第三，两种中介效应检验结果显示，FDI通过技术创新机制作用于我国经济高质量发展。第四，整体而言，FDI通过技术创新水平这一中介路径对经济高质量发展产生负向影响，与理论预期不符。
