由于企业的对外直接投资(OFDI)存在制度适应成本,东道国与母国之间的制度距离会对企业OFDI产生负向影响。基于2003—2015年中国对140个国家和地区OFDI的分析表明:中国企业的OFDI具有明显的市场寻求动机和战略资源寻求动机,其中,市场寻求型OFDI表现出显著的互补效应,战略资源寻求型OFDI表现出一定程度的挤出效应;东道国与中国的制度距离会通过投资动机影响中国企业OFDI的区位选择,即倾向于向制度距离较小的国家和地区进行OFDI,且制度距离会弱化市场寻求型OFDI的互补效应和战略资源寻求型OFDI的挤出效应。站在企业角度来看,中国企业在进行OFDI时并不具有“制度风险偏好”,而是表现出“制度风险规避”特征:选择对其自身发展来讲制度风险较小(制度距离较小)的目标市场进行OFDI。因此,中国应深化市场经济体制改革,提升国内制度质量,加强国际经济合作,并增强企业的制度适应能力,以有效减小制度距离对企业OFDI区位选择的约束,进而优化OFDI区位分布,提高OFDI效益和质量。  相似文献

Based on construal level theory, this research addresses the moderating role of an individual's psychological distance towards a disease in the effectiveness of advertising messages framed by two distinctive construal level terms (high-level and low-level). In Experiment 1, two different disease types (bronchitis/distant disease vs. influenza/proximal disease) were featured, with the result that an advertisement with high-level construal terms was more persuasive for a psychologically distant disease (bronchitis) than for a psychologically proximal disease (flu). The reverse was true for an ad framed with low-level construal terms. To replicate Experiment 1 and further test the hypothesis, in Experiment 2, the perceived distance individuals have towards one disease (cancer) was measured and used as independent variable. Consistent with the results from Experiment 1, the low-level construal messages were more effective under the psychologically close condition than the psychologically distant condition. Reverse was true for the high-level construal messages.  相似文献

Finite mixtures offer a rich class of distributions for modelling of a variety of random phenomena in numerous fields of study. Using the sample interpoint distances (IPDs), we propose the IPD‐test statistic for testing the hypothesis of homogeneity of mixture of multivariate power series distribution or multivariate normal distribution. We derive the distribution of the IPDs that are drawn from a finite mixture of the multivariate power series distribution and multivariate normal distribution. Based on the empirical distribution of the IPDs, we construct a bootstrap test of homogeneity for other multivariate finite mixture models. The IPD test is applied to mixture models for matrix‐valued distributions and a test of homogeneity for Wishart mixture is presented. Numerical comparisons show that IPD test has accurate type I errors and is more powerful in most multivariate cases than the expectation–maximization (EM) test and modified likelihood ratio test.  相似文献

为了消除在构建谱聚类算法的相似矩阵时,高斯核函数中尺度参数的波动影响,构建了一种自适应相似矩阵,并应用到谱聚类算法中。自适应相似矩阵中数据点间的距离度量采用测地距离算法,相距较近的两点间的距离近似于欧氏距离,相距较远的两点则先根据欧氏距离得到每个数据点的k个近邻点,然后累加近邻点的测地距离,由此得到每对数据点间的最短距离。两点间的局部密度用共享近邻的定义来表示,更好地刻画了数据集的本征结构。在5个人工数据集和国际通用UCI数据库中的5个真实数据集上进行实验。实验结果表明,所提算法的聚类准确率高于对比算法的准确率,对复杂分布数据有很强的自适应能力。研究成果为数据挖掘及机器学习提供了思路和方法。  相似文献

In this paper, we estimate the effect of “cultural distance” on bilateral trade in services. The measure of cultural distance we use is based on scores that reflect country averages of individuals’ attitudes towards inequality, self-orientation, competition, uncertainty, traditions, and indulgence. Controlling for standard ingredients of gravity equations, we show that an aggregate measure of cultural distance has a significantly negative effect on total bilateral services trade. Once we take a more disaggregate view, we find that the strength of this effect differs across various types of services and various aspects of cultural distance.  相似文献

近年来,在领导特质研究领域,自恋领导得到了学者的广泛关注。尽管现有研究探讨了自恋领导对下属的影响效果,但鲜有研究从领导与下属人际互动视角揭示自恋领导的作用机制。本研究基于领导特质过程模型和权威互补理论,探讨自恋领导对下属绩效的影响,并挖掘其内在影响机制以及作用边界条件。通过对一家保险公司进行多时点、多来源的问卷调查,研究结果表明:自恋领导对下属绩效具有显著的负向影响;关系冲突在其中起中介作用;下属权力距离负向调节了自恋领导与关系冲突之间的正向关系,即下属权力距离越低,自恋领导与关系冲突的正向关系越强,反之则越弱。此外,当下属权力距离较低时,关系冲突的中介作用更强,反之则被削弱。  相似文献

The reduction of non-performing loans, and making correct provisions for them, plays a primary role in the management and minimization of banking credit risk. However, these actions depend primarily upon the cost at which banks may dispose of these bad loans. Hence, this study aims to perceive the price of banks’ credit risk via estimating the shadow price of non-performing loans. We assess and compare the perceived price of the credit risk of Islamic and conventional banks operating in 9 countries from the Middle East and Asia, using a quadratic directional distance function. Following this, we evaluate the impact of different settings of directional vectors on shadow prices by conducting a risk-sensitivity analysis. Applying bootstrap regression, the factors affecting NPLs’ prices are further investigated. The paper concludes that the estimation of the shadow prices of bad loans can provide important elements in favor of credit risk management and, therefore, credit risk mitigation.  相似文献

The purpose of this research is to contribute to the ongoing debate about whether psychic distance still plays a vital role in the internationalisation of SMEs from emerging markets. Drawing on the prior research which suggests the salient impact of institutional factors on internationalisation, we investigate the role of home country institutions in international market selection. Adopting a multi-case methodology, we collected semi-structured interview data from six small and medium-sized manufacturing firms in China. Our findings suggest that while psychic distance is still important in some circumstances, both formal institutions, such as government support, and informal institutions, such as business and political guanxi, enable Chinese SMEs to choose psychically distant markets. Our findings also indicate that informal institutions interact with formal institutions to further influence SMEs’ international market selection. This research contributes to SME internationalisation studies by revealing how formal and informal institutional factors override psychic distance in influencing international market selection.  相似文献

本文首先通过语义内涵解读、现象考察和比较分析构建了穿越认知逻辑分析框架,然后从语义学视角应用发生学方法、心理距离理论,通过逻辑分析构建旅游时空穿越回环结构、旅游穿越过程结构机制模型,并对旅游穿越结构进行过程机制分析。研究结论认为:旅游的时空转换结构是一种穿越结构,旅游穿越表现出完整的时空穿越特征,具有人类穿越式对话的典型性;旅游结构的本质是时空穿越;旅游穿越就是通过物理时空转换建立心理距离,最终达成心灵对话之目标。因此,旅游运行的核心矛盾就是解决由物理空间转换带来的交通需要和由穿越式对话带来的旅游实景营造需要,从而实现心理时空穿越。本文通过对旅游结构本质的追问,将"穿越"这一日常化语言抽象为学术语言,形成旅游学内生性概念和范畴,为旅游体验活动提供了一种新型的解释话语,并为不同类型穿越结构、穿越感问题的研究拓展了探讨空间。  相似文献

This paper reviews and synthesizes literature on foreign listing from international business, management, and finance disciplines. A systematic review of 66 studies from 25 journals indicates fragmentation of the literature across the macro and firm-specific perspectives and a limited usage of current international business theories in research on foreign listing. We propose multiple developmental paths including use of institutional theory, especially institutional distance and institutional evolution to provide more comprehensive understanding of antecedents and contingent factors for foreign listing; supply-chain disaggregation of cross-border capital flow; integrate financial and strategic implications of foreign listing; and advancement of emerging market specific theories.  相似文献
