刍议我国企业的供应链合作关系

供应链各节点企业间的战略合作关系是供应链管理的核心问题,也是促使供应链整体效率优化的必然选择。但是,在我国的实践中企业的供应链合作关系令人担忧,其主要原因是内部管理水平低下、三流关系不畅通和法制法规的不健全。因此,应采取提高企业内部管理水平、加强激励与监督机制和完善我国的法制与法规等策略,来建立供应链合作关系。     

我国商业银行技木创新中的问题及对策

目前，我国商业银行正在积极地进行技术创新，并取得了一定的成效。但随着信息化进程的推进，出现了业务处理系统缺少有机整合、产品创新技术含量低、风险管理技术手段落后等问题，制约了我国商业银行金融创新的系统性和科学性。今后应采取诸如大力提升银行自主创新能力、完善技术创新的成本一效益评估机制、建立先进的风险量化衡量体系和管理系统、全面推进决策支持系统的建设等措施，提升我国商业银行的技术创新能力。     

论生态经济学主流化的障碍

生态经济学的理论和方法正越来越多地在社会经济实践中得到应用,但生态经济学目前仍然远离经济学的主流。本文认为,只有正确解决“经济人”假设,与传统经济学理论的整合以及准确地进行学科定位等重大问题,同时不断丰富完善生态经济学的内容体系,才有可能实现生态经济学的主流化。     

Evidence of a homeowner-renter gap for electric vehicles

This paper provides the first empirical analysis of the homeowner-renter gap for electric vehicles. Using newly-available U.S. nationally representative data, the analysis shows that homeowners are three times more likely than renters to own an electric vehicle. The gap is highly statistically significant, and remains even after controlling for income. For example, among households with annual income between $75,000 and $100,000, 1 in 130 homeowners owns an electric vehicle, compared to 1 in 370 renters. Additional controls do little to narrow the gap. The paper argues that this is a version of what economists have called the “landlord-tenant’’ problem, and briefly discusses potential policy implications.     

Optimal consumption and investment under transaction costs*

In this paper, we consider the Merton problem in a market with a single risky asset and proportional transaction costs. We give a complete solution of the problem up to the solution of a first‐crossing problem for a first‐order differential equation. We find that the characteristics of the solution (e.g., well‐posedness) can be related to some simple properties of a univariate quadratic whose coefficients are functions of the parameters of the problem. Our solution to the problem via the value function includes expressions for the boundaries of the no‐transaction wedge. Using these expressions, we prove a precise condition for when leverage occurs. One new and unexpected result is that when the solution to the Merton problem (without transaction costs) involves a leveraged position, and when transaction costs are large, the location of the boundary at which sales of the risky asset occur is independent of the transaction cost on purchases.

Family ownership and environmental performance: The mediation effect of human resource practices

Previous literature has found that listed family firms underperform their nonfamily counterparts in terms of environmental performance, but has not explained why this occurs. We address this research gap by hypothesizing that training and development practices (i.e., managerial practices devoted to providing training and development for the workforce) mediate the relationship between family blockholders and environmental performance. Using a sample of 33,901 firm‐year observations from 2002 to 2016 distributed across 56 countries and employing the structural equation model technique, we find that investment in training and development practices explains almost half of the negative relationship between family blockholders and environmental performance. Our study contributes to the agency theory debate on principal–principal problems by explaining why family blockholders could damage other blockholders and minority shareholders.     

新经济地理学框架下跨国公司区位选择因素分析

中国作为全球最大货物贸易国和最大外汇储备国,许多跨国公司纷纷来华投资。虽然受疫情的影响,在世界经济出现严重衰退和部分地区出现暂时停摆现象,但在华投资势头强劲,总额占世界首位。区位选择与对外直接投资之间存在着不可分离的关系,是跨国公司在海外投资时必须考虑的重要环节。良好地利用外资可以促进我国在经济上的国际交流,拉动区域经济增长和协调发展,所以研究跨国公司在中国选址时的参考因素具有实质意义。     

WHAT DO WE KNOW ABOUT THE IMPACT OF INTELLECTUAL PROPERTY RIGHTS ON THE FOREIGN DIRECT INVESTMENT LOCATION (COUNTRY) CHOICE? A REVIEW AND RESEARCH AGENDA

Despite a longstanding debate, at both a theoretical and empirical level, research on the relationship between foreign direct investment (FDI) and intellectual property rights (IPRs) remains scant and ambiguous. As a result, the link between IPR strength and multinational enterprises’ (MNEs) propensity to invest is unproven and seemingly dependent on a number of factors. We critically review the theory and evidence of the influence of IPRs on FDI and MNEs’ investment location (country) decisions both to ‘take stock’ of existing knowledge of this relationship and, by identifying gaps in, and shortcomings of prior work, develop a fruitful research agenda. We find that existing empirical work on the IPR–FDI nexus, though skewed in favour of a positive relationship between IPR protection and FDI, is fragmented, inconclusive and unable to square the conflicting theoretical predictions on how the strength of IPRs can affect MNEs’ FDI location decisions. Several issues and challenges are highlighted to explain the difficulties of the collective body of past empirical work to provide a definite answer to the question of the impact of IPRs on FDI, from which valuable recommendations are proposed to guide future applied research.
