In this paper, we examine the impact of foreign direct investment (FDI) on local urban inequality in China. Specifically, we consider the FDI policy change as an exogenous shock on the local labour markets. We find that cities that have experienced a bigger policy change in promoting FDI between 1997 and 2002 are significantly more unequal in 2005. This pattern is mainly driven by the positive association between FDI liberalisation and skill premia. The result holds after we control for other policy changes, such as privatisation of state-owned enterprises, infrastructure and trade liberalisation. We then turn to investigate the mechanisms using firm and individual-level information. Our firm-level evidence shows that FDI firms not only hire relatively more high-skilled workers but also provide relatively higher wages to high-skilled workers compared to domestic firms. Moreover, the individual-level analysis shows that FDI has a significantly positive spillover effect on wages received by skilled workers employed by state-owned enterprises, but not wages of unskilled workers.  相似文献

Using firm-level data, this paper examines the effects of foreign investment on the exporting behaviour of domestic firms in the Vietnamese manufacturing and service sectors. Applying the Heckman selection model on panel data and following the Wooldridge approach, we find that investment by foreign firms has a significant positive effect on the decision of domestic firms in the same and upstream sectors to export. The proportion of exports of domestic firms declines through horizontal and forward linkages, but increases through backward linkages in the manufacturing sector. However, there is only weak evidence in support of export spillovers on domestic firms in the service sector. We also find that the presence of foreign firms has differing effects on the exporting activities of low- versus high-tech firms in the manufacturing sector.  相似文献

In this paper, we investigate how de facto financial globalisation has influenced the labour share in developing countries. Our main argument is the need to distinguish between different types of capital in this context as they differ in their effect on the host countries' production process and vary concerning their bargaining power vis-à-vis labour. Our econometric analysis of the impact of foreign direct versus portfolio investment in a sample of about 40 developing and transition countries after 1992 supports this claim. Using different panel data techniques to address potential endogeneity problems, we find that foreign direct investment has a positive effect on the labour share in developing countries, while the impact of portfolio investment is significantly smaller and potentially negative. Our results also highlight that de facto foreign investment cannot explain the decline of the labour share in developing countries over the investigated period.  相似文献

This study investigates the factors that affect South Korean outward foreign direct investment (FDI) in developing countries. Most previous studies focus on monadic factors and do not consider how and to what extent bilateral relationships between South Korea and the host countries affect the investment decisions of Korean firms. The current study finds that interstate factors such as South Korea's international investment treaties with and official development assistance to host countries have positive effects on FDI to these countries, while presidential visits have strong and statistically significant effects on FDI only in countries located in non-Asian regions, especially the African continent. The findings suggest that the effects of bilateral relations on South Korea's FDI vary depending on the geographic location of the host country.  相似文献

Using a Korean manufacturing firm-level data set covering a range of years from 2006 to 2013, this study investigates how the financial condition of firms, such as liquidity, leverage, and cash flow ratio, affects exit from export markets. It also analyses whether the financial status of foreign multinational corporation (MNC) subsidiaries differs from that of domestic firms with respect to the hazard of export market exit, especially during a global financial crisis. The empirical results confirm that, for domestic firms, the hazard of export market exit is affected by the firms’ financial condition only during a financial crisis. In other words, the financial vulnerability of domestic firms increases during the crisis, resulting in the hazard of export market exit. However, financial situations for foreign MNC subsidiaries do not affect exits from export markets, indicating a ‘finance-factor comparative advantage’.  相似文献

This research analyses the impact of foreign direct investment on greenhouse gas emissions in the agriculture sector of developing countries. Panel data from 63 developing countries for the period 2005 to 2014 was used to estimate a dynamic econometric model by applying a system‐generalised method of moments. The empirical results indicate a positive impact of foreign direct investment in agriculture on the carbon dioxide equivalent emission intensity in developing countries. The results provide weak support for the pollution havens hypothesis and imply the importance of coordination between foreign direct investment and environmental policies.  相似文献

ABSTRACT

Natural language query systems over RDF data need to rely on the semantic relations in query. First, we propose the new crowdsourcing model that used to produce semantic relations dataset. The model not only inherits completeness of the iterative model and accuracy of the parallel model, but also saves human resources. Second, we mine the rules of semantic relation recognition from the correlations between dependency structures and semantic relations. Third, we propose an algorithm of semantic relation recognition for natural language query over RDF data, and experiments demonstrate that it can recognize more semantic relations than existing methods.  相似文献

外商直接投资(FDI)可以通过劳动力需求效应和技术溢出效应改变东道国的劳动力就业结构和行业相对劳动生产率,进而影响行业工资差距,并且这种影响具有不确定性;由于投资动机和进入方式的不同,FDI对行业工资差距的影响具有异质性并表现为地区差异。基于中国服务业的经验分析发现:外资进入通过增加低工资行业的相对就业规模和提升高工资行业的相对劳动生产率扩大了行业工资差距,适应中国低技能劳动力丰裕而高技能劳动力相对稀缺的劳动力市场条件;在以垂直型和合资型FDI为主的地区外资进入具有显著的扩大行业工资差距效应,而在以水平型和独资型FDI为主的地区这一影响并不明显。因此,应努力提高劳动力人力资本水平并充分保障低技能劳动力的权益,积极鼓励和引导水平型FDI进入并适度减少垂直型FDI的引入,持续增强企业的技术吸收能力并不断缩小技术差距,进而在高效利用外资的同时缩小行业工资差距。  相似文献

This study aims to use computational linguistics, visual analytics, and deep learning techniques to analyze hotel reviews and responses collected on TripAdvisor and to identify response strategies. To this end, we collected and analyzed 113,685 hotel reviews and responses and their semantic and syntactic relations. We are among the first to use visual analytics and deep learning-based natural language processing to empirically identify managerial responses. The empirical results indicate that our proposed multi-feature fusion, convolutional neural network model can make different types of data complement each other, thereby outperforming the comparisons. The visualization results can also be used to improve the performance of the proposed model and provide insights into response strategies, which further shows the theoretical and technical contributions of this study.  相似文献

The aim of the study is to investigate the nexus between tourism and income inequality by employing the Autoregressive Distributed Lag (ARDL) test cover the period 1974–2015 in Turkey. Findings indicated that the variables are cointegrated and an increase in tourism has a positive effect on income inequality, while economic growth and trade openness have a negative effect both in the long-run and short-run. Results also denote that tourism will decrease income inequality with the expansion of tourism activities and the spread of tourism throughout society. In other words, the tourism-related Kuznets Curve hypothesis is valid for Turkey.  相似文献
