企业创新需求与政府创新补贴的激励效果

本文将创新需求定义为"企业根据自身创新活动意愿和资金约束情况做出的最优创新投资决策",并从企业创新需求异质性的视角对政府创新补贴的激励效果进行了分析.利用Nvivo软件,对2008-2015年间A股非金融类上市公司年报进行文本分析,得到企业创新意愿的代理变量,并通过理论建模和实证检验,对创新意愿和资金约束如何影响政府创新补贴与创新投入的关系进行分析.结果发现,创新意愿能显著提升政府创新补贴的激励作用,但只有在资金约束程度较高时,企业创新意愿强化政府创新补贴与企业创新投入之间的正向作用才最为有效.进一步研究显示,创新意愿与企业创新投入、专利产出显著正相关,且企业创新意愿越强,分析师关注度也越高,说明本文构建的创新意愿是真实可信的.本文丰富了有关企业创新行为的研究,为相关部门筛选创新补贴对象提供了借鉴意义.     

非参数核密度估计在异方差模型中的应用

针对非参数核密度估计中最优窗宽的选择在实际建模中的不足,提出了一个新的最优窗宽选择的迭代方法,克服了使用传统的经验法则所带来的局限性。并在此基础上用一种新的非参数核密度估计ML方法应用到了中国股票市场,通过与极大似然估计对比论证了此方法的有效性和可行性。实证分析表明,通过与实际值的模拟对比,运用非参数估计技术得到上证指数日收益率的拟合值要优于极大似然估计的拟合值。

Off-Farm Employment and Grain Marketable Surplus in China

This paper examines the effects of off-farm employment on grain marketable surplus supply during the reform period in China. A theoretical framework demonstrates that farm households' supply behaviour depends not only on the profitability of farm production but also on alternative off-farm wage opportunities of household members. An empirical model, which assumes full income maximisation of farm households, simultaneously evaluates the effects of on-farm and off-farm income on their grain supply behaviour. Particular attention is paid to the effect of off-farm income through a comparison of conditional and unconditional grain marketable surplus supply elasticities. Results show that off-farm income had a strong negative effect on grain marketable surplus from farm households following liberalisation of factor markets in China and that this could lead to a loss of marketable surplus supply.     

Munificence,Dynamism, and Complexity: How Industry Context Drives Corporate Sustainability

Does external industry context exert an influence on the development of corporate sustainable development? In keeping with the view that environmental responsibility generates new and competitive resources for firms, we posit that three distinct industry contextual characteristics, namely munificence, dynamism, and complexity, can influence corporate environmentally responsible behaviors. Our conceptual framework is supported by empirical evidence that draws on a sample of 746 Chinese listed firms in manufacturing sectors. Our findings suggest that dynamism increases the likelihood of firms behaving in environmentally responsible ways, whereas complexity decreases this likelihood. The relationships between dynamism and environmental responsibility are stronger in firms with low levels of organizational slack. Moreover, we find that resource‐abundant firms are more likely to behave responsibly toward the natural environment in a high‐munificence industry context.
