20世纪以来,俄罗斯经历了乌克兰危机、西方经济制裁、国际油价下跌等外部因素的冲击,经济安全遭受严重威胁,在此背景下的俄罗斯政治经济战略势必波及中俄经贸合作,进而影响丝绸之路经济带建设。本文从贸易合作和对外直接投资合作方面,基于计量模型剖析俄罗斯国家经济安全对中俄经贸合作的影响过程及关联因素。研究表明俄罗斯国家经济安全危机提升了中国在俄贸易伙伴国中的地位,促使俄与中国产能合作的意愿强烈,直接投资和产能合作逐渐成为推动中俄经贸合作向纵深发展的强劲动力;俄罗斯国家经济安全危机对中俄罗贸易有显著负向影响,中俄政治关系对贸易合作有显著正向影响。这是提高中国对俄罗斯投资、提升高新技术产品在俄罗斯进口比重的机遇期,亦是推进丝绸之路经济带的重要机遇期。经济强势崛起的俄罗斯和经济体系全面崩溃的俄罗斯对丝绸之路经济带的推进均有重要影响,在与其发展战略协作伙伴关系过程中,中国恰到好处地拿捏平衡其中的大国利益边界至关重要。  相似文献

The development of information and communications technology (ICT), particularly the Internet, has reduced trade costs. However, it remains unclear whether these reduced costs are reflected in the “extensive margins” of firms’ exports (which refer to the probability of firms exporting) or the “intensive margins” (which refer to the value of firms’ export). To test this, we used the concepts of information cost and binary margins, an augmented trade model of firm heterogeneity, a two‐stage Heckman estimation, and data from the World Bank Enterprise Survey of Chinese firms in 2012. The results revealed that reduced trade costs from the use of ICT were positively related to extensive margins but that the connection with intensive margins was not significant. The results lead to the conclusion that reduced information costs related to a firm's exporting behavior were primarily reflected in variable trade costs. This study offers theoretical and empirical evidence for China's policies towards the Internet, which are relevant for the export of manufactured goods. The government should encourage the use of ICT to enhance firms’ export opportunities while facing current trade policy uncertainty.  相似文献

This is the first paper to show that participation in an international environmental agreement has some effectiveness. Our identification strategy consists of applying difference-in-differences techniques in a panel data framework to various levels of data aggregation. We find that ratification of the Rotterdam Convention (RC) and the Stockholm Convention (SC) leads to a reduction in trade of hazardous substances from OECD to non-OECD countries. In particular, we find that when the exporter ratifies the RC, there is a reduction in the import of hazardous chemicals of about 7 percent. In the case of the SC, the results show significant reductions of around 16 percent in trade shipments of persistent organic pollutants. This reduction is more than double the effect found for the RC, which was expected due to a more restricted obligation imposed by the SC convention.  相似文献

We study the factors influencing the percentage of organic and fair trade certified coffee sold through a cooperative by growers of five cooperatives in Mexico. The percentage of coffee sold through the cooperative was used as a proxy of growers’ engagement with a cooperative. Using factor analysis and a fractional probit regression, we evaluated the proposition that the level of engagement can be explained by transaction cost economics, social norms and connections, and farmer and farm business characteristics. We found that farm size, uncertainty regarding cooperative time of payment to the members and cooperative commitment on price to be paid negatively influence the level of engagement. In contrast, asset specificity, relational commitment, and price have a positive impact on engagement. Our results may help cooperatives and policy makers to build strategies aiming to increase this level of engagement. This is relevant because lower grower engagement has been found to be positively correlated with weak performing cooperatives.  相似文献

We examine differences in information content between order submission sizes and trade sizes by U.S. equity traders. Increasing (decreasing) order submission (trade) size is reflective of information. The result suggests that better-informed traders want to trade in a large size, but that they engage in stealth trading practices or break larger orders into smaller sizes in order to conceal information. While prior studies tend to narrowly focus on trade executions at the market-centre level, our findings indicate that order submission size varies significantly from trade size and that both sizes are informative about future prices, albeit in an inverse manner.  相似文献

The persistence of agricultural protectionism throughout the world is intriguing given the widely recognized benefits of free trade. The political economy literature over the last decades has considered groups’ interest, politicians’ preferences, and their interactions within domestic politics as the primary forces driving agricultural protection. Yet, a growing body of studies suggests that it would be judicious to weigh in consumers’ or taxpayers’ perspectives in deciphering the nature of agricultural protection. This study examines U.S. citizens’ preferences about government intervention in agriculture and trade. Results show that they are in strong support of agricultural protection and their perceptions of national food security, family farms, environmental sustainability, and multifunctionality of agriculture play a significant role in shaping their support/opposition toward government intervention. The conventional political economy literature theorizes that consumers or taxpayers would oppose public policies that increase their tax burden; however, in the case of the farm sector, they have little incentive to voice their objections given the costs of farm programs are spread across a large number of consumers and taxpayers. U.S. citizens’ support for government involvement in agriculture as reported in this and other prior studies does not lend support for such political economy explanation.  相似文献

ABSTRACT

Creating free trade zones as a policy to motivate new investment and improve the local economic indicators might be of some benefits. Following of this policy in Iranian major port, however, resulted vice versa by aggravating the current account balance that is higher imports and the same horizon diminished export sums. We derive the micro data of trade for the Iranian major Imam port according to code arrangements of harmonic system (HS), which permits the clustering of different goods categories. Then we extracted the sums of survey data for the years before and after Imam port became free trade zone and applied fixed effect difference in difference (DID) method to capture the heterogeneity of unobserved variables. Our control port of analysis was Rajaee port the policy did not implemented. Results show that just as Imam free port’s Current Account Balance deteriorated by increasing import and dampening of export sums.  相似文献

ABSTRACT

This paper examines the manufacturing export market in Egypt after the Arab Spring using a novel firm-level census dataset from 2013. Export is very rare in Egypt. The conventional export premia are very high, except for total factor productivity. Exporters have stark effects on labour market outcomes, including wages, employment, demand for skilled and female workers, wage inequality, and job security. These findings have two important implications: (1) Manufacturing exports might be monopolized by large firms, and (2) promoting exports could improve labour market outcomes, especially for skilled and female workers.  相似文献

Abstract:

Global commodity chains reflect and affect gendered labor markets. This article uses the Decent Work framework from the International Labour Organization to analyze employment outcomes for Indonesian workers in manufacturing. This research investigates trends in feminized manufacturing sectors in variously sized firms. Regression analyses is used to evaluate how firm characteristics related to global production sharing effect decent work outcomes for women and men, as well as female share of employment itself. The results suggest that exports and FDI affect men and women differently and that feminization and decent work outcomes depend on how the sector is positioned along the global value chain.  相似文献

从“海南自贸区(港)建设”战略、链接国家“一带一路”倡议视角出发,建立海南现代物流与对外贸易指标评估体系,根据协调发展度模型对海南2009-2018年现代物流和对外贸易发展的协调性进行测评。结果显示:海南现代物流综合发展指数高于对外贸易综合发展指数,海南对外贸易发展滞后于现代物流发展;海南现代物流与对外贸易发展逐渐呈协调发展趋势,二者协调发展水平不断提高。在此基础上提出强化国际物流协同建设、拓展对外贸易新业态与新模式等促进海南现代物流与对外贸易协调发展的建议。  相似文献
