营商环境、企业家精神与技术创新关系研究

优化营商环境、激发市场主体活力是我国新时期推动经济高质量发展的重大举措。选取2009-2018年30个省市级面板数据,构建中介效应模型,实证分析营商环境质量对企业家精神的激励效应及技术创新的促进作用。研究发现：①营商环境优化对中国技术创新具有显著正效应,但其影响更多表现为资金供给而非制度供给;②企业家精神是营商环境与技术创新的中介变量,营商环境要素、企业家创新精神和创业精神激励结构对技术创新的影响存在异质性;③营商环境显性激励作用明显,但内生激励不足。研究结论可为持续优化营商环境、激发企业家精神、促进技术创新提供政策启示。

Dynamic causality between the U.S. stock market,the Chinese stock market and the global gold market: implications for individual investors’ diversification strategies

This paper proposes a generalization of the prior VAR and EGARCH model to explore the linkage between returns and volatility transmissions in the U.S. stock market, the Chinese stock market, and the global gold market from 10 July 1996 to 20 July 2018. We found that past returns of the U.S. stock market can predict the current returns of the other two markets, and that significant reciprocal volatility transmission existed within and across all three markets. We further implemented average out-of-sample (OOS) forecasting to show that a risk-adjusted portfolio, such as mean-variance with sample estimator, does not outperform an equal-weighted portfolio. This provides insights for individual investors and helps to explain the ongoing disagreement in the portfolio literature concerning the effectiveness of risk-adjusted portfolios and equal-weighted portfolios when the number of assets is small.

State ownership and firm performance: Empirical evidence from Chinese listed companies

While the relationship between state ownership and firm performance has been widely researched, the empirical evidence has provided mixed results. This study applies panel data regression techniques to 10,639 firm-year observations of non-financial Chinese listed firms during 2003–2010 to examine the relationship between state ownership and firm performance. The results show that state ownership has a U-shaped relationship with firm performance. The Split Share Structure Reform in 2005–2006 played a positive role in enhancing the relationship between state ownership and firm profitability ratios. Although state ownership decreased significantly after 2006, it remains high in strategically important industry sectors such as the oil, natural gas and mining sector and the publishing, broadcasting and media sector. The findings reveal that a higher level of state ownership is superior to a dispersed ownership structure due to the benefits of government support and political connections. The Split Share Structure Reform made previously non-tradable shares legally tradable, improving corporate governance and reducing the negative effect of non-tradable state shares.
