伴随着新媒体的发展,“中国大妈”和与其结构类似的“中国式X”的网络流行语正在受到越来越多的关注。代表一种独特的文化现象的“中国式X”,本身就是一个语言模因,它的各种次生语言形式在模因的作用下得以在社会大众之间广泛繁殖和衍生。我们既可以从认知语言学的概念重叠和概念整合角度对“中国大妈”的形成及其所隐含的调侃语义进行解读,也可以从社会文化学领域的模因论视角对“中国式X”的传播进行探讨。 相似文献

In this paper, we examine the match between resource relatedness and post-merger integration on technology innovation of acquiring firms to find the rationale behind technology-sourcing cross-border mergers and acquisitions (M&As) of Chinese multinational enterprises. Using a sample of 88 Chinese technology-sourcing cross-border M&As, we find that the acquirer will improve technology innovation when greater resource similarity between the acquirer and target firms is matched with a high integration degree and a low target autonomy level. Meanwhile, the acquirer can improve technology innovation when greater resource complementarity is matched with a low level of integration degree in technology-sourcing cross-border M&As. This paper provides the acquiring firms with fresh ideas of how to make the integration decisions of technology-sourcing overseas M&As. We hope to help multinational enterprises to achieve more outstanding technology innovation performance through technology-sourcing overseas M&As in an intense global competitive environment. 相似文献

Two main shortcomings flaw the estimation of gravity model in previous studies that examined the trade-creating effects of African Regional Trade Agreements (RTAs). First, these studies fail to account for the multilateral resistance term. This omission makes the estimates from standard gravity model bias and inconsistent. Second, there is a significant proportion of zero trade flows, however, these studies also fail to account for them properly. They use either the Tobit model or replace zero flows with arbitrary small values. Apart from these problems, they also exhibit considerable heterogeneity in the RTA effects on trade. In this paper, a meta-analysis of previous empirical studies is conducted to derive a combined effect size and also to explain the heterogeneity. In addition, I use the gravity model to compare the trade-creating effect of the main African RTAs. Using the gravity model, I compare the estimation methods of previous studies to the Poisson pseudo-maximum-likelihood estimator that tackles the zero flows. From the meta-analysis, I find a general positive effect of African RTAs of about 27%–32%. A comparative assessment of the RTAs using gravity model shows a striking heterogeneity. 相似文献

Macroeconomic policy choices in open economies are constrained by the trilemma according to which the objectives of exchange rate stability, monetary independence and capital mobility cannot be attained jointly. This paper shows that foreign exchange interventions provide an effective instrument to relax the trilemma. An active reserve policy allows central banks to pursue independent monetary and exchange rate policies when the capital account is liberalised.We use the framework of the portfolio balance model to show that exchange market interventions may substitute for capital controls. Both allow a country to achieve the other two objectives of the trilemma. Our empirical analysis of a large country panel data set covering the period 1970–2010 confirms this theoretical insight: the weighted sum of the three trilemma objectives increases in the degree of foreign exchange market intervention. The capacity to relax the trilemma constraint has increased over time and has been most effective in emerging markets. 相似文献

National borders continue to be strong barriers for mergers and acquisitions in Europe. Using regional data, we construct a gravity model and find that the restraining impact of national borders decreased by more than 17 percent between 1991 and 2007. However, no significant change has occurred since the mid-1990s (i.e., four years before the introduction of the euro). In comparison, we run a corresponding analysis in the United States using the 10 federal regions as country equivalents. The resulting ‘quasi-border’ effect in the United States is weaker than that in the European Union. Yet its decline by 43 percent is much stronger in the same period. We conclude that European integration policy has had little effect on fostering M&A cross-border transactions. 相似文献

We investigate the relationship between a country's domestic financial development and the (composition of its) net foreign asset position using a pooled mean group estimator and data for 50 countries for the 1970–2007 period. The results show that financial development reduces a country's long-run net foreign asset position. In addition, financial development leads to higher net equity and lower net debt positions. These findings confirm the theoretical predictions of Mendoza et al. (2009). The results are robust to using different indicators of financial development and inclusion of the level of development of a country in the cointegrating relationship. 相似文献
