The Benefit of Frequent Corporate Philanthropy

Applying behavioural economic theory, we argue that the frequency of philanthropic activity is important in determining corporate philanthropy's economic outcome. Using Chinese data from 2003 to 2016, we find that firms with more frequent philanthropic activities obtain more government subsidies than firms that only engage in one-off charitable donations. Firms with better corporate governance, such as higher management ownership and more independent directors, are more likely to adopt a strategy of frequent donation. Furthermore, firms are more likely to be frequent donors when management or local government officers have a long tenure. Our findings provide insight into the giving process and suggest that firms can maximize the benefit of corporate philanthropy if they strategically consider the donation frequency and donation amount simultaneously.

The finance-growth nexus: The role of banks

We contribute to the finance-growth nexus literature by showing that credit origin, bank ownership, type of credit, and bank type matter in economic growth. We use a unique dataset covering 5555 cities in Brazil, with granular information on credit characteristics. We find that non-earmarked credit to the corporate sector is associated with municipal economic growth more strongly than earmarked credit, despite the increase in the relevance of the latter after the global financial crisis. We also find that the type of credit—whether the loans are general purpose or for a specific purpose—is associated with economic growth in different ways. Overall, credit provided to the corporate sector by domestic private banks is correlated with higher economic growth rates. In contrast, the relationship between credit from state-owned banks and economic growth becomes statistically significant only after the crisis. Although we follow the finance-growth literature in our empirical exercises using internal instruments in generalized method of moments (GMM) estimations, we also conduct robustness tests using two additional external instruments: the number of complaints filed against each bank and local credit accessibility. Our findings with external instruments are the same with respect to the use of traditional internal instruments in GMM estimations.

产业升级、金融分权与民营企业融资约束

本文在产业升级的框架下,分析了国有企业对民营企业存在的信贷挤入与挤出效应.产业升级过慢或过快都将使得信贷挤出效应占主导,金融分权(Ⅰ、Ⅱ)是产业升级影响民企融资约束的重要金融渠道,基于2007-2016年中小板上市公司数据和省级宏观数据,主要通过现金-现金流敏感性模型进行了实证检验.结果表明:(1)相对于产业升级速度适中地区,过慢和过快地区的民营中小企业融资约束更为严重;(2)国企产业升级通过决定金融分权影响民企融资约束,金融分权Ⅱ本身能缓解民企融资约束,但国企产业升级过快会降低金融分权Ⅱ,同时金融分权Ⅰ会刺激地方政府过度投资反而会加剧民企融资约束;(3)金融分权对民企融资约束的影响受到财政分权的显著调节作用,地方财政越宽松,金融分权的作用越显著;(4)对产业升级过慢地区,在金融措施配合下,充分发掘国企产业升级先导性作用是缓解民企融资约束的有效途径.     

会计信息质量、制度环境与企业创新绩效

创新是实现经济高质量发展的强大引擎,更是企业生存发展的重要因素,企业创新绩效是近年来学者们研究的热点话题之一.本文基于2008—2017年A股上市企业的数据,研究了会计信息质量能否促进企业创新绩效的提升,以及制度环境是否在二者之间发挥调节效应.研究发现:会计信息质量较高的企业能够提高企业的治理水平并缓解企业的资金压力,进而显著提高创新绩效;制度环境能对公司研发投资产生激励作用;此外,制度环境还在会计信息质量与企业创新绩效之间起到显著调节作用.从产权性质的角度进一步分析表明,上述结论仅在民营企业中成立,而在国有企业中不显著.从融资约束角度进一步分析表明,融资约束在会计信息质量与企业创新绩效之间起到了中介传导作用.     

一种动态加权的LDPC译码方法

为了加快低密度奇偶校验（LDPC）码的译码速度，有效改善LDPC码的译码性能，针对校验节点更新过程中的对数似然比（LLR）值的大小，设计了一种LDPC码的动态加权译码方法。以IEEE 802.16e标准的奇偶校验矩阵为例，根据LLR值的变化规律，利用增长因子和抑制因子对和积译码算法和最小和译码算法进行动态加权。仿真结果显示，基于动态加权的译码方法相对于传统译码方法误码率都有明显改进，译码复杂度也有所降低。     

重症患者CT增强检查的护理分析

目的探讨在重症患者CT增强检查过程中加强护理干预的效果。方法选取2013年1月至2014年1月我院行CT增强检查的128例重症患者的临床资料进行归纳整理,分析检查过程中患者的不良反应发生情况及CT增强检查结果。结果除1例患者因气喘、憋闷,未能完成增强检查外,127例患者均顺利完成增强检查。结论在重症患者CT增强检查的过程中加强护理干预,可有效预防意外事故的发生,保证检查顺利进行。
