人力资本与技术溢出:基于进口传导机制的实证研究

本文研究了以进口贸易为传导机制的国际技术溢出对我国全要素生产率的影响。结果表明，通过进口贸易传导机制，国内研发、贸易伙伴国溢出的研发与我国全要素生产率之间存在着稳定的长期均衡关系；国外研发溢出是与人力资本相结合采促进全要素生产率提高的，人力资本在技术溢出中发挥着关键的作用。     

Weak Ties in Networked Communities

Communities with high levels of social capital are likely to have a higher quality of life than communities with low social capital. This is due to the greater ability of such communities to organize and mobilize effectively for collective action because they have high levels of social trust, dense social networks, and well-established norms of mutuality (the major features of social capital). Communities with “bridging” social capital (weak ties across groups) as well as “bonding” social capital (strong ties within groups) are the most effective in organizing for collective action. People who belong to multiple groups act as bridging ties. When people with bridging ties use communication media, such as the Internet, they enhance their capability to educate community members and to organize, as needed, for collective action. This article summarizes evidence from stratified household survey data in Blacksburg, VA, showing that people with weak (bridging) ties across groups have higher levels of community involvement, civic interest, and collective efficacy than people without bridging ties among groups. Moreover, heavy Internet users with bridging ties have higher social engagement, use the Internet for social purposes, and have been attending more local meetings and events since going online than heavy Internet users with no bridging ties. These findings may suggest that the Internet—in the hands of bridging individuals-is a tool for enhancing social relations and information exchange, and for increasing face-to-face interaction, all of which help to build both bonding and bridging social capital in communities.     

审计师质量对资本结构的影响——基于联立方程的研究

对于审计师质量与资本结构之间的关系,现有实证研究并不充分,而在理论上,对于这两者之间的关系存在不同的预测。本文利用我国2008-2011年A股上市公司及其主审会计师事务所数据,以行业专长和规模作为审计师质量的替代变量,实证考察我国上市公司基本完成股权分置改革这一背景之下审计师质量对资本结构的影响。结果发现,如果不考虑审计师质量与资本结构之间的相互影响,审计师质量对资本结构没有显著影响;而在考虑这两者之间可能存在相互影响并采用联立方程方法来解决这一内生性问题后,审计师质量对资本结构具有显著的负向影响。进一步研究表明,上述负向关系在国有企业中要比在非国有企业中更为明显。此外,上述负向关系存在于法治环境、信贷环境较好地区,而在法制环境或信贷环境较差的地区,并不显著。

利用民间资本发展我国科技风险投资业的研究

本文认为，我国科技风险投资业应当由国有资本为主向民间资本为主转变。在分析利用民间资本发展科技风险投资业现实可行性的基础上，本文构建了四种类型以民间资本为主体的科技风险投资组织模式，并从税收、财政、市场退出、规范管理等方面提出激活民间投资进入科技风险投资业的政策支持措施。     

基于人力资本价值因子的高层管理团队与企业绩效关系模型研究

国内外学者研究高层管理团队与企业绩效的关系过多地关注于高层管理者的特征数据本身,而忽视了隐藏在数据背后的决定变量。基于人力资本价值的视角,采取定性与定量研究两种方法,从高层管理团队的能力、努力水平、合作程度、贡献、素质和人力资本产权的界定等权变因素及其变化对企业绩效的影响,探讨其内在机理关系,构建了高层管理团队人力资本价值构成因子与企业绩效的关系模型。     

An empirical investigation of information sharing behavior on social commerce sites

Social commerce sites (SCSs), a new model of social media, provide fertile ground for customers to communicate their opinions and exchange product- or service- related information. Given the significant opportunities related to the use of social media data for customers’ insight, we explore the factors driving information sharing behavior on SCSs. In this paper, we propose and empirically test a comprehensive theoretical model for customer information sharing behavior through analysis of online survey data as well as network and behavioral usage data of over four months from 1177 customers in a SCS. The research model was empirically validated with the use of both subjective and objective data in a longitudinal setting. Our results show that customer information sharing is influenced by both individual (i.e., reputation and the enjoyment of helping others) and social capital (i.e., out-degrees’ post, in-degrees’ feedback, customer expertise and reciprocity) factors. This study contributes to the existing literature by highlighting the role of directed social network in customer information sharing behavior on SCSs. We believe that the results of our study offer important insights to the IS research and practice.
