This article presents a multilevel framework to analyze the motivations and location choices of Chinese OFDIs. We contribute to theory‐integration on Chinese OFDI flows and patterns by suggesting a framework that combines country‐, industry‐ and firm‐level analyses and by reflecting aspects from the resource‐based view (firm‐specific advantages), institutional‐based view (push/pull home‐ and host‐­country factors), and network‐based view (network relations). We also explicitly incorporate “time” as a variable into our framework by introducing and explaining the concept of dynamic embeddedness as an interaction dimension to reflect the inherent dynamics on all levels and actors. © 2017 Wiley Periodicals, Inc.  相似文献

This paper analyzes the persistence of firms’ exporting behavior in a panel of German manufacturing firms using dynamic binary choice models. We distinguish between true and spurious state dependence in exports and apply fixed effects methods that allow us to verify the robustness of our results to critical assumptions on firms’ initial export status. We find robust evidence of state dependence in the current export status of firms. We also document an important role of unobserved permanent firm heterogeneity (spurious state dependence) and quantify the relative importance of different export determinants. Our results, which are consistent with the findings of previous studies on firms in developing countries and in the United States, show the presence of important sunk costs in export market entry and a depreciation of knowledge and experience in export markets. This paper benefitted substantially from three anonymous referees and Bernd Fitzenberger, one of the editors of this journal. The authors wish to thank the Centre for European Economic Research (ZEW), Mannheim, for its hospitality during the time this study was carried out. Both authors gratefully acknowledge helpful comments received at a workshop hosted by the Centre for Applied Microeconometrics, University of Copenhagen workshop, especially those from Bo Honoré. Useful discussions with Georg Licht also lead to improvements of this paper. We thank Ken Chay for sharing Gauss codes used in parts of the paper. Lastly, we would like to thank Bettina Peters, a member of the ZEW team that compiles the data set used in this study, for data guidance and numerous helpful comments. The activities of the Centre for Applied Microeconometrics are financed by a grant from the Danish National Research Foundation.  相似文献

An econometric study of tourist arrivals in Aruba and its implications   总被引:1,自引:0,他引:1  
The principal purpose of this study is to analyze econometric estimates in order to explain tourist arrivals to Aruba from the United States, The Netherlands and Venezuela. The study specified a dynamic econometric model for modeling short term as well as the long-term responses. It estimated both linear and log-linear functions, and it applied the Box–Cox statistical method to determine the appropriate functional form. The inclusion of Venezuela as a developing country permitted the comparison of the behavior of tourism demand in relatively rich and poor countries. The results indicated the extent to which cross-country behavior of demand differs with respect to changes in effective prices and exchange rates. This study can assist in the formulation of future macroeconomic policies as well as market and pricing strategies in a small or microstate economy.  相似文献

Dynamic Preference Maintenance   总被引:1,自引:1,他引:0  
WERTENBROCH  KLAUS  CARMON  ZIV 《Marketing Letters》1997,8(1):145-152
Consumers' choices and evaluations can sometimes be interpreted as goal-driven attempts to manage some of the internal and external resources and constraints that affect subsequent purchase and consumption choices. For example, delaying gratification involves limiting immediate benefits in favor of better future ones. We refer to this self-management of resources and constraints as dynamic preference maintenance and illustrate this concept with a number of marketing examples. We discuss evidence and practical and conceptual implications for marketing.  相似文献

This paper shows that, under certain conditions (including path dependence and lock-in), policies and measures leading to a cost-effective GHG emissions mitigation in the short term may not allow reaching long-term emissions targets at the lowest possible cost, that is, they might not be cost-effective in the long term. The reason is that, in a situation where currently expensive technologies have a large potential for cost reductions through learning effects and R&D investments, the implementation of incentive-based mitigation policies such as taxes or tradable permits will encourage the adoption and diffusion of currently low-cost abatement technologies, but might not be enough to make attractive the diffusion of expensive ones, which is a necessary condition for these technologies to realise their cost-reduction potential through the aforementioned effects. A simple model and a numerical simulation are provided to show this possible conflict between static and dynamic efficiency, which points out to the need to combine different instruments, some aiming at short-term cost-efficiency (such as incentive-based environmental policy) and others at encouraging dynamic cost reductions (such as technology/innovation policy).  相似文献

贸易与环境问题的研究动态与述评   总被引:6,自引:0,他引:6  
傅京燕 《国际贸易问题》2005,109(10):124-128
环境问题除了构成一国的资源禀赋外,还影响到生产成本、贸易模式、产业区位以及贸易利得。从20世纪70年代起,随着许多工业化国家相继实施环境规制,环境问题在国际贸易领域开始变得重要起来。本文对贸易与环境问题研究的主要文献进行回顾,从而有助于理解贸易与环境质量之间的复杂联系。  相似文献

WTO后过渡期出口企业反倾销摩擦原因及对策的博弈分析   总被引:2,自引:0,他引:2  
入世使中国成就了贸易大国的梦想,但却是多年连续位居全球受反倾销调查指控最多的国家,中国的对外贸易正在陷入一轮又一轮的反倾销摩擦的囚徒困境之中。文章通过建立动态博弈模型,尝试性地寻求这一问题的内在博弈原因和应对策略,最后提出了"四体联动"应诉机制角色分工和分层预警机制的构想。  相似文献
