FOREIGN ENTRY INTO U.S. SERVICE INDUSTRY BY TAKEOVERS AND THE CREATION OF NEW FIRMS

We study the relation between foreign entry in U.S. service sector industries and the revealed comparative advantage of the investing country using U.S. Bureau of Economic Analysis firm‐level data on all foreign takeovers and new foreign‐owned firms from 1998 to 2008. We find foreign acquisitions in the service sector are in industries of U.S. comparative advantage while new foreign firms are in industries of investing country's comparative advantage. This suggests that foreign acquisitions in the service sector are not directly related to foreign investors' competitiveness in the industry of investment. In contrast foreign investors in new service sector firms come from countries with a competitive edge in the industries of investment. We also find that foreign investors of new service sector firms are from Organization for Economic Co‐operation and Development (OECD) countries with a comparative disadvantage in royalties and trademarks.

企业环境技术创新采纳的行为决策研究

分析了环境技术创新采纳的特点,对其研究现状进行了归纳和总结,指出决策的有限理性是现有理论对其解释不足的重要原因。结合传统决策及行为决策理论的发展,以文献研究和调查研究相结合的方法提取主要的理性变量和行为变量,建立了企业环境技术创新采纳的行为决策框架。     

集群企业技术能力构建的案例研究——基于能力矩阵

基于能力矩阵的分析框架,对集群企业的技术能力构建过程和基于OEM关系的超集群知识联系对该过程的影响进行了理论分析。以巴基斯坦的Sialkot集群和我国台湾地区的机床产业集群为案例对象,通过研究两集群中生产商的技术能力构建过程对相关命题进行检验。结论如下:集群企业的技术能力构建是一个多路径过程;基于OEM关系的超集群知识联系对集群企业技术能力构建的作用具有一定局限性;集群企业通过利用这类超集群知识联系开展富于进取心的、积极主动的学习,可以突破该局限性,克服价值链中领导企业设置的障碍,从而可以在更宽的功能范围内构建创新程度更高的技术能力。     

个人住房抵押贷款违约风险影响因素实证研究-以杭州市为例

随着银行个人住房抵押贷款余额的快速上升,个人住房抵押贷款违约风险日益成为人们关注和研究的焦点。本文应用杭州市某国有商业银行信贷数据,采用Logistic模型实证研究发现影响当前个人住房抵押贷款的违约因素按重要性排序依次为:是否为当地人、贷款价值比、期房还是现房、月还款额占家庭月收入的比例、还款方式、家庭收入和建筑面积。本文进一步应用不完全合同理论解释了结论背后的制度含义,并提出了相应的治理措施。     

有备无患：后续疫情中新冠焦虑对武汉员工防护和工作的影响研究

国内局部疫情陆续暴发,关注已有疫情经历的员工防护和工作行为对疫情防控有一定意义。基于资源保存理论,文章假设新冠焦虑对武汉员工防护行为和工作结果有显著影响,且对防护行为影响大于对工作结果的影响。在2021年初国内局部疫情期间,对52名武汉员工连续5天的调查发现,每日新冠焦虑通过每日新冠耗竭显著提升武汉员工新冠防护行为,但武汉员工每日工作产出不受疫情影响,包括工作绩效、创新绩效、工作导向和人际导向的帮助行为。文章揭示了有2020年新冠肺炎疫情直接经验的武汉员工对待后续疫情防护的谨慎态度,以及在工作结果方面对后续疫情的“抗干扰性”。结合当前情况,讨论了研究结果对疫情防控和经济恢复的实践意义。     

Evaluation of medical costs associated with use of new oral anticoagulants compared with standard therapy among venous thromboembolism patients

Objective:

This study evaluated differences in medical costs associated with clinical end-points from randomized clinical trials that compared the new oral anticoagulants (NOACs), dabigatran, rivaroxaban, apixaban, and edoxaban, to standard therapy for treatment of patients with venous thromboembolism (VTE).

Research design and methods:

Event rates of efficacy and safety end-points from the clinical trials (RE-COVER, RE-COVER II, EINSTEIN-Pooled, AMPLIFY, Hokusai-VTE trial) were obtained from published literature. Incremental annual medical costs among patients with clinical events from a US payer perspective were obtained from the literature or healthcare claims databases and inflation adjusted to 2013 costs. Differences in total medical costs associated with clinical end-points for the NOACs vs standard therapy were then estimated. One-way and Monte Carlo sensitivity analyses were carried out.

Results:

A lower rate of major bleedings was associated with use of any of the NOACs vs standard therapy. Except for dabigatran, use of NOACs was also associated with a lower rate of recurrent VTE/death. As a result of the reduction in clinical event rates, the overall medical cost differences were ?$146, ?$482, ?$918, and ?$344 for VTE patients treated with dabigatran, rivaroxaban, apixaban, and edoxaban, respectively, vs patients treated with standard therapy.

Conclusions:

When any of the four NOACs are used instead of standard therapy for acute VTE, treatment medical costs are reduced. Apixaban is associated with the greatest reduction in medical costs, which is driven by medical cost reductions associated with both efficacy and safety end-points. Further evaluation may be needed to validate these results in the real-world setting.     

异质性机构投资者差异化作用于双元创新投资吗——基于注意力基础观与市场迎合理论双重视角

基于2011-2020年沪深A股高新技术企业样本,探究公司治理框架下异质性机构投资者对企业双元创新投资的差异化作用机理,得出如下结论：①异质性机构投资者对于双元创新投资具有差异化影响,其中,专注型机构投资者更有利于双元创新投资;②专注型机构投资者影响决策者注意力资源配置,使其更注重探索性创新投资,临时型机构投资者基于市场迎合动机作用于开发性创新投资,且当管理层业绩和外部监管压力较大时,其对开发性创新投资的迎合动机更明显;③专注型机构投资者通过监督和激励管理层、提升企业风险承担水平作用于企业双元创新投资,临时型机构投资者通过丰富投资者情绪作用于开发性创新投资未得到验证;④产业政策有助于增强专注型机构投资者对决策者注意力的影响,使其更专注于探索性创新投资,同时也有助于提高临时型机构投资者的开发性创新迎合投资动机。研究结论为理解机构投资者差异化治理角色提供了一种新视角。
