This paper investigates how pre‐existing preferential trade agreements (PTAs) dilute the trade creation effect and shield the trade diversion effect of new PTAs. Countries having pre‐existing PTAs enjoy smaller gains in intra‐bloc trade because of the dilution effect and experience smaller losses or even gains in extra‐bloc trade because of the shielding effect. The findings support the proposition that PTAs could be used to fend off future trade diversion.  相似文献

We study parametric and non‐parametric approaches for assessing the accuracy and coverage of a population census based on dual system surveys. The two parametric approaches being considered are post‐stratification and logistic regression, which have been or will be implemented for the US Census dual system surveys. We show that the parametric model‐based approaches are generally biased unless the model is correctly specified. We then study a local post‐stratification approach based on a non‐parametric kernel estimate of the Census enumeration functions. We illustrate that the non‐parametric approach avoids the risk of model mis‐specification and is consistent under relatively weak conditions. The performances of these estimators are evaluated numerically via simulation studies and an empirical analysis based on the 2000 US Census post‐enumeration survey data.  相似文献

Municipal mergers have become a worldwide phenomenon in the past few decades, primarily advanced to exploit economies of scale. While most evaluations of municipal mergers have focused on the efficiency of local public goods provision, it is rare in the literature to explore how such mergers promote economic growth in a developing country context. This research investigates the economic consequences of a policy experiment of city–county mergers (che xian she qu) in China during the period 2000–2004. Using comprehensive datasets at city, county and firm levels, we present evidence that the merger significantly increases local economic development, and the magnitude of the effect depends on local endowments related to agglomeration forces. The results are robust to a number of different model specifications. We further verify that improved transport infrastructure and urban agglomeration economies after merger are potential contributors to the positive merger effects.  相似文献

We offer new theory and evidence regarding the effects of pro-market institutions on outward foreign direct investment (FDI) of emerging market firms (EMFs). Drawing on the logic of institutional arbitrage, we integrate the escapism and exploitation mechanisms of EMF internationalization into a unified theoretical context. We propose an inverted U-shaped relationship between host market-supporting institutions (MSI) and the investment scale of an EMF’s FDI project in the country, showing an escape-driven upward slope for low-to-medium MSI levels and an exploitation-driven downward slope for medium-to-high MSI levels. We supplement this main argument with two boundary conditions: the alleviating effect of home market liberalization (HML) and the strengthening effect of home government subsidies (HGS), demonstrating the coexistence and variation of pro- and anti- market institutions in an emerging market. Using information on 1,450 FDI projects conducted by 288 Chinese listed firms in 116 host countries, we obtain supportive evidence for the predicted relationships between the three institutional forces. This study enriches the literatures on institutional arbitrage and pro-market institutions with evidence from EMFs.  相似文献

以从2006年开始实行的环境约束性指标为研究对象,结合晋升锦标赛和弱排名激励理论,提出了官员排名赛理论,认为约束性指标制度的建立为地方政府提供了环境绩效排名的平台,由此推动了地方政府环境政策执行力度。利用2006—2015年中国省际环境数据,采用动态面板数据估计方法,实证检验了各省环境绩效排名对其未来环境政策执行力度的影响。实证结果表明,环境绩效排名落后的省份在未来1~3年显著提高了节能和减排的政策执行力度。  相似文献

创客组织是实现组织协同创新的重要载体。创客位于组织协同系统的核心层,创客入驻创客组织的创新状态决定了协同创新发展状态;创客组织位于组织协同系统的中间层,起组织协调作用,其发展稳定性影响着整个系统;协同组织位于外部层,其参与程度决定了整个系统的组织协同和协同创新吸引能力。基于波动系数计量模型,对240家创客组织的12项评价指标进行分析,结果显示,以高校主导的创客组织衡量指标波动系数为标准,创客组织在整体上处于发展不稳定状态;分类别分析结果表明,高校和科研院所主导的创客组织发展稳定性明显优于企业和个人主导的创客组织。研究结果可以为完善创新政策、促进创客组织稳健发展提供参考。  相似文献

Over the past 30 years, China has fully exploited its advantage to steadily foster an innovation system for the biomedical industry with Chinese characteristics, that is, ‘Government-guided, resource-integrated and long-term planning.’ The system originated from historically famous ‘863 program’ in the 1980s, evolved with a series of favourable policies in the different periods, and eventually has taken shape in the industrial clusters across the country. It features with a systematic and integrated R&D infrastructure (or public platform) at different levels. In this study, China’s biomedical innovation system will be examined and the leading role of Chinese authorities will be explored from the perspective of Triple Helix theory. As the ‘highland of innovation’, Shanghai case is highlighted with plentiful information gathered from primary sources in the involved agencies for the first time, including the Shanghai Biopharma Service Platform.  相似文献

In most cases, bidder's stock returns around merger announcement convey more information than the synergy created from the acquisition. To overcome the interpretation problem, I study the bidder's return from the perspective of deal termination. Using a hand‐collected dataset on terminated merger proposals, I investigate termination returns in deals canceled for reasons unrelated to the bidder's stand‐alone valuation. I find that bidder's gain varies significantly with the type of target acquired. Further evidence suggests that the liquidity need of private target significantly contributes to the positive gain to the bidder.  相似文献
