数字普惠金融对高技术制造业创新韧性的影响——基于系统GMM与门槛效应的检验

基于2011—2019年中国内地30个省份面板数据,运用系统GMM和门槛效应模型,检验数字普惠金融对高技术制造业创新韧性的影响以及消费升级和研发投入强度的门槛效应。结果表明,数字普惠金融及其覆盖广度、使用深度和数字化程度均对高技术制造业创新韧性具有显著正向影响;消费升级、研发投入强度分别在数字普惠金融对高技术制造业创新韧性的影响中表现出单一门槛效应和双重门槛效应。进一步的地区异质性研究发现,数字普惠金融仅对中西部地区高技术制造业创新韧性起到提升作用,消费升级在东部和中西部地区分别表现出双重门槛效应与单一门槛效应,研发投入强度在东部和中西部地区均表现出单一门槛效应。研究结果有助于丰富数字普惠金融应用于高技术制造业相关研究,为高技术制造业利用数字普惠金融提升创新韧性提供实践启示。     

Market competition, social welfare in an entry-constrained differentiated-good oligopoly

This paper studies a differentiated-good oligopoly where the socially optimal number of firms (varieties) may be smaller or greater than under the free-entry equilibrium. We show that, under certain conditions, social welfare may be higher when entry is restricted into the industry.     

A longitudinal study of the impact of market structure,firm structure,strategy, and market orientation culture on dimensions of small-firm performance

The purpose of this article is to determine market orientation’s relative impact on small-business performance, compared to other influences, in an integrated model using longitudinal data. Contrary to expectations based on the management literature, the results indicate weak causal relationships between market environment, small-firm structure, and small-firm strategy. The results further indicate weak influences of these variables, but strong and consistent influences of market orientation, on various measures of small-firm performance. Contrary to expectations based on business policy literature, relative product quality and new product success were not significant influences on profitability, perhaps due to the significant influence of market orientation on these variables. In addition, although increases in growth/share had a significant short-term influence on increases in profitability, high levels of previous years’ firm growth/share had a negative influence on current profitability. The previous year’s level of firm coordinating systems and market competitive intensity has a significant impact on the level of small-firm market orientation.     

Value creation in the relationship life cycle: A quasi-longitudinal analysis

Among the growing literature on value creation in collaborative buyer-seller relationships, most researchers examine relationship value at a single point in time. In the present research, we explore whether different stages of the relationship life cycle moderate the relative importance of value-creating dimensions. To shed light on the dynamic nature of value in B2B relationships, we present the results of a survey among purchasing managers using a quasi-longitudinal research design. Our findings confirm the moderating role of the relationship life cycle in value creation. More precisely, our results indicate that a key supplier's potential for value creation in customer's operations increases in relative importance as relationships move through the life cycle. In turn, supplier's capabilities to create superior value at the level of the customer's sourcing process display a decreasing role over the life cycle of a business relationship. No significant link was found in the present study between value creation through a supplier's core offering and different stages of a buyer-seller relationship.

Crowdfunding and social influence: an empirical investigation

The literature so far provides no in-depth investigation of the determinants of decisions to contribute to crowdfunding platforms. The present article draws on work measuring the decisions and prosocial behaviours of individuals in relation to public goods, and uses survey data on crowdfunding behaviour. We surveyed an original sample of individuals in France to explore individual decisions and amounts of funding chosen to support a creative project. We show that in non-equity crowdfunding contributing money is associated with altruism. Our findings suggest that the ‘warm glow’ effect influences the level of the contribution; we show also those monetary incentives could ‘crowd out’ the decisions to contribute of crowdfunders. Our study has some implications for business strategy since understanding why people contribute adds to our knowledge about the incentives that might encourage them to increase their contributions, and allows predictions about how changes to how crowdfunding platforms are managed might affect individual incentives to give.     

Strategic Internet application trends in supply chain management

The Internet is evolving as a powerful force in the new marketplace where the nexus of competition has changed from individual firms to efficient supply chain networks both between firms and within industries. This study explores Internet adoption patterns and operational applications in US supply chain networks. The data reveal that the integration of the Internet into supply chain management applications has increased and has moved away from indiscriminate application of novel Internet technologies towards becoming a focused endeavor with precise expectations and measurable goals. Specifically, the study finds that Internet usage within supply chains is maturing as evidenced by enhanced and increased productivity, reduced costs and increased profit for participating firms.     

The devolution of HR to the line: Implications for perceptions of people management effectiveness

The devolution of human resource responsibilities from human resource managers to line managers is both a growing and global trend. A number of authors has suggested that there are positive as well as negative consequences of devolution. The current study conducted a survey of US human resource managers to explore the effect of devolution on human resource managers' perceptions of people management effectiveness in their organizations. Results revealed a positive effect of devolution on perceived people management effectiveness. However, this effect was qualified by an interaction between devolution and line support. Contrary to expectation, this interaction revealed that providing line managers with training and support for their human resource responsibilities had a greater positive impact on perceived effectiveness in organizations that had not devolved (non devolvers) compared to those that had (devolvers).
