众创空间类型如何塑造创业服务行为？基于制度逻辑视角的分析

文章基于制度逻辑视角,以浙江省746家众创空间为样本,分析了政府、高校、民营企业三类主体设立的众创空间和创业服务行为选择的关系。研究发现：（1）制度逻辑对众创空间的创业服务行为选择具有塑造作用,持有行政逻辑的政府型众创空间会将时间更多的分配给办公场所服务,而持有专业逻辑的高校型和持有公司逻辑的民企型众创空间,则分别会将时间更多的分配给培训咨询服务和投融资服务。上述发现在替换了其它两种因变量测量指标后依然成立。（2）国家级认证会使民企型众创空间显著减少在投融资服务上的时间分配比重,而显著增加在办公场所服务和培训咨询服务上的时间分配比重,这种调节效应在另外两类众创空间中并不显著,在替换了省级认证后结果依然成立。这表明,相较于公司逻辑,政府逻辑和专业逻辑更具稳定性,更不易受高阶制度因素的影响和干扰。文章拓展了制度逻辑和众创空间创业服务行为关系的理论认识,为创业者的众创空间入驻决策以及政府针对众创空间的政策制定提供了实践启示。

优化营商环境与外资企业FDI动机——市场寻求抑或效率寻求

在优化营商环境已成为当前发展中国家引资竞争新优势的背景下,针对优化营商环境影响外资企业FDI动机的考察变得尤为重要。本文在构建企业层面营商环境指数的基础上,考察了发展中国家优化营商环境影响外资企业FDI动机的机制及效应。结论表明:优化营商环境减弱(增强)了外资企业的市场(效率)寻求型FDI动机;内资企业竞争力的增强、外资企业特惠资源的取消和加工贸易型外资企业的存在,使得优化营商环境降低了外资企业的生产率,进而市场(效率)寻求型FDI动机减弱(增强)。细分样本的考察发现,上述结论仅存在于独资企业、工业和低收入国家的外资企业中,对于合资企业、服务业和高收入国家的外资企业,优化营商环境对其FDI动机无显著影响,且生产率的中介效应不存在。本研究从优化营商环境的视角为当前中国引资政策的制定提供了更为具体的政策启示。

Cross-national differences in stakeholder management: Applying institutional theory and comparative capitalism framework

Drawing upon the research in institutional theory and comparative capitalism, the present study investigates how cross-national differences in the political, business, and economic institutional contexts of the United States, Italy, and Japan are associated with the ways in which companies in each of these countries prioritize and engage in their stakeholder engagement activities (SEAs). Using Porter and Kramer's framework, which classifies corporate social responsibility (CSR) activities as falling into four categories (good citizenship, mitigating harm from value chain, transforming value chain activities, and strategic philanthropy), we investigate how companies in the United States, Japan, and Italy prioritize and engage in these four SEAs. An analysis of data collected from 340 companies across these countries reveals that while companies in each of these three countries undertake the four types of SEAs, the prioritization and prevalence of the four types of SEAs vary from one country to the other, in ways that align with the prevailing institutional contexts of each country. The results contribute to a more nuanced understanding of why and how companies' approaches to CSR differ across countries. From a practitioner's perspective, the findings highlight the cultural specificity of CSR, implying that despite the global nature of CSR, the implementation of CSR needs to be tailored to a country's context.     

经济政策不确定性、区域经济复杂度与企业创新行为

构建包含宏观经济政策不确定性指标、区域经济复杂度和上市公司特征变量“宏观-区域-企业”的实证面板数据，在理论分析经济政策不确定性对企业创新行为作用机理的基础上，以区域经济复杂度为视角，对经济政策不确定性与企业创新行为作用机制进行再检验。研究发现：经济政策不确定性对企业创新存在正向激励综合效应，同时，区域经济复杂度不仅能够促进企业创新行为，而且能够强化经济政策不确定性对企业创新行为的影响即抑制负向作用而强化正向作用。考虑内生性，通过替换核心变量检验稳健性以保证研究结论可靠，并且，研究企业特征发现，高科技企业和非高科技企业存在差异。     

户籍制度扭曲及放松对经济的影响:理论与实证

户籍制度是我国劳动力流动的主要障碍.那么,当前我国的户籍扭曲程度几何?户籍制度放松对经济又会有怎样的影响?对这些问题的回答将有助于政府评估户籍制度改革的空间和经济效益.文章在Hansen和Prescott(2002)的两部门劳动力流动模型基础上,将工人分为农业和非农户口,引入户籍扭曲因子,构建两部门两类工人的户籍扭曲模型;然后,使用1984?2013年宏观经济数据度量户籍扭曲程度,并对2013年我国户籍制度逐渐放松过程中经济变量的变化进行模拟;最后,文章建立了包含"农业与非农"和"本地与外地"户籍差异的省份异质性户籍扭曲模型.研究表明:(1)经济和户籍制度改革的不同步导致了1984?2013年我国户籍扭曲程度呈现倒"U"形变化,且相较于韩国尚有较大的改善空间;(2)以韩国为参照,若2013年我国户籍制度完全放开,经济达到均衡时,农业部门和非农部门的就业人数将分别下降58.83%和上升26.92%,工资率将分别上升19.44%和下降6.77%,社会增加值将增长15.33%,这说明社会经济效率将得到提升,贫富差距将缩小.文章丰富和完善了户籍扭曲的理论模型,从减少劳动力流动摩擦的视角为政府制定相关政策提供了参考.     

Does Institutional Blockholder Short‐Termism Lead to Managerial Myopia? Evidence from Income Smoothing

We examine institutional blockholders’ influence on income‐smoothing practices in the Korean market, which provides an interesting setting where family‐oriented chaebols dictate the corporate landscape and impede shareholder activism. The empirical results reveal that institutional shareholders with a short‐term (long‐term) investment horizon facilitate (constrain) managerial myopia. This positive (negative) association is most evident among firms with domestic institutional investors. Therefore, we argue that the presence of domestic institutional investors with transient investment goals incentivizes firms’ management to smooth out earnings.     

一种级联两箱通用数字预失真器及其辨识算法

提出了一种由单形规范线性分段(SCPWL)函数与记忆多项式级联的数字预失真器，并给出了复数域两步最小二乘参数辨识算法。不同于以往一种预失真器适用一种功放模型的情况，所提的预失真算法利用SCPWL函数的分段特性以及记忆多项式的非线性记忆特性，在完成参数辨识的同时自动地调整结构，可适用于传统以及强非线性新型功放模型的线性化补偿。将所提预失真器分别应用于传统记忆多项式、两箱模型以及新型包络跟踪功放。经过计算机仿真，功放输出的幅频特性和频谱曲线表明所提预失真器能够有效地补偿多种功放的非线性特性。算法仿真比较结果也表明，针对包络跟踪功放，所提复数两步最小二乘算法的邻道泄漏比(ACLR)可改善约35 dB，性能优于最小均方(LMS)类算法约30 dB。     

Resource Dependence and Network Relations: A Test of Venture Capital Investment Termination in China

This study examines how venture capital (VC) firms terminate investments in an emerging economy context. We contend that due to the weak institutional environment, it is appropriate to draw on insights from power and social relation perspectives for a better understanding of the phenomenon. Specifically, we argue that a termination decision hinges on not only the dependence relationship between a VC firm and its portfolio companies, but also the social relationships among VC firms. Event history analyses of approximately 12,000 VC deals made in China between 2001 and 2012 reveal that when a VC firm has a greater number of investments in an industry, it is more likely to terminate investments on a portfolio company in that industry. Moreover, such effect on termination is moderated by the focal VC's embeddedness with its syndicate partners and collaboration opportunities with other VC firms outside the immediate access of the syndicate partners. Our study sheds light on research on VC decision making in emerging markets by integrating insights from resource dependence relationships and interorganizational network characteristics.
