利用2003-2015年我国内地30个省份的省际面板数据,在概述对外直接投资影响一国创新能力作用机制的基础上,借鉴Lichtenberg和Pottelsberghe提出的国际研发溢出测算方法,从技术差距视角出发,运用面板门槛模型实证检验二者间的关系。结果显示:对外直接投资可以通过R&D成果反馈效应、并购整合效应以及产业前后向关联效应提升一国创新能力;在不同的门槛取值区间内,OFDI逆向技术溢出对创新能力提升的作用呈显著倒U型特征,只有在最优技术差距区间内才能发挥其最大效应。最后,在作用机制概述和实证研究结论基础上,从政府和企业两个层面提出政策建议。  相似文献

We propose a North-South model that reconciles trade and production strategies, flows of innovators and the path of economic divergence, or convergence, between countries. We explain the mechanisms behind these forces and show how the technological and economic gaps can be reversed if southern countries stop imitating northern goods and, instead, produce complementary goods. Such a strategy of complementarity on production yields the necessary incentives to innovators to engage in research in southern countries, which enhances the catching-up process between countries. It is also shown that migratory movements of unskilled labor between countries are also relevant to understand the dangers and benefits of different trade strategies for economic growth. This paper suggests a positive (negative) correlation between technological innovation in the North (South) and the level of substitutability in production, while under complementarity, technological innovation catches up in the South, therefore fostering the economic catching up process. A positive correlation between inflows of skilled and unskilled labor and substitutability of production between countries is also verified.  相似文献

We investigate the impact of direct payments on agricultural commercialisation in Kosovo. Kosovo is one of the poorest countries in Europe but, with European assistance, provides substantial funds to support agriculture, made up of many small and often semi‐subsistence farms. Thus, the effect of this support is a central policy issue. Identifying the effect of direct payments on market participation faces endogeneity issues arising from the possible simultaneous determination of participation in support programmes and market participation. In order to achieve proper identification of the endogenous direct payments, we use a strategy of targeted identification search that employs several different methodological approaches. We find that direct payments for fruit and vegetables, and those for cereals and oilseeds have a positive effect on market participation. However, we cannot identify any definite effect of livestock payments.  相似文献

This study examines how direct democratic institutions affect income distribution before and after taxes. Based on a panel of Swiss cantons from 1945 to 2014, we test the effects of the constitutional reforms of direct democratic instruments. Our findings show that better voter access to the initiative induces policy shifts that significantly decrease top incomes and benefit the upper middle class. For the popular referendum we do not find such effects. The income effects of direct democracy are not a consequence of shifts in fiscal redistribution, but rather result from policy changes affecting pre-tax incomes.  相似文献

将库存理论运用到铁路始发直达运输产品设计,能够有效实现运输服务组织成本与库存成本的有机统一。为实现库存成本在铁路始发直达运输中的加载,在考虑周期非完整情况下的库存成本的同时,将铁路运输和库存成本纳入同一目标函数,在装卸车地库存能力约束下,构建基于库存理论的铁路始发直达运输产品设计模型,确定成本最小的铁路始发直达运输产品设计方案。以赤峰地区至山东省煤炭运输网络为例,设计方案有效降低了成本,有助于吸引客户选择铁路运输,以及辅助铁路运营单位研究调整始发直达运输产品方案。  相似文献

文章基于我国服务业上市企业数据,采用多维固定效应模型,探讨和分析了我国服务业OFDI对服务贸易出口的影响,经研究发现:第一,服务业OFDI通过吸收东道国先进技术经验提升企业生产率水平和避开东道国服务贸易壁垒降低贸易成本,促进企业服务贸易出口增长;第二,我国服务业OFDI显著提升了企业服务贸易出口的二元边际,具体而言,整体上服务业OFDI会促进服务贸易出口增长4.82%,同时会提升企业的出口概率;第三,我国服务业OFDI"出口效应"存在明显的区域和行业的异质性,具体表现为:生产性服务业和消费性服务业OFDI存在显著的"出口效应",其OFDI带动服务贸易出口的增长分别为5.68%和3.52%,而公共服务业则不存在显著的"出口效应";东部地区和中部地区服务业OFDI存在显著的"出口效应",其OFDI带动区域服务贸易出口的增长分别为4.97%和3.56%,而西部地区则不存在显著的"出口效应"。上述研究结论对化解我国服务贸易出口增长困境和完善服务业对外直接投资政策机制具有一定的启示意义。  相似文献

Foreign Direct Investment (FDI) has been recognised as a major influence upon urban development within emerging economies. As the focus of production shifted toward higher skills and advanced technologies, expatriate high-skilled employees of the Multinational Enterprises (MNEs) began to play a significant role in FDI projects and recipient cities begin to experience urban development associated with residential development and community services for the settlement of these expatriate staff. This research reports on the experience of Korean investment in real estate following earlier projects in manufacturing activity in the Hanoi Capital Region. Korean investors are currently the largest FDI source in Vietnam and Hanoi has been favoured by them. The purpose of this research is to examine that the urban impact of manufacturing FDI on a recipient city is magnified by its connections with Real estate FDI (RFDI) in a way that it spurs (1) intensified real estate development, (2) the creation of new urban cores, and (3) new commuting patterns. The clustering of Korea-specific residential development and service functions is a contribution to change in Hanoi. The Korean-built housing complexes have transplanted Korean-style housing design into gated communities and the residents continue their Korean life-styles with easy access to language-specific community facilities. This research sheds light on the coalescent nature of RFDI with overall FDI via flows of MNEs and expatriate staff that can generate direct and indirect spatial impacts at project, city and regional scales.  相似文献

基于2000—2017年省际面板数据,运用静态面板与门限面板模型,通过建立以政府干预、市场化进程为门限变量的回归模型,实证分析了外商直接投资与区域创新对我国城市化发展的影响。研究结果表明:外商直接投资、区域创新对城市化发展有积极的带动作用,同时,外商直接投资对区域创新的作用由替代效应向互补效应转变;政府干预对外商直接投资存在双重门限效应,对区域创新存在单一门限效应;市场化对外商直接投资存在单一门限效应,但对区域创新存在双重门限效应。基于以上结论,进一步提出促进城市化发展的建议。  相似文献

Are people’s attitudes towards referendums as a decision-making procedure predominantly driven by their material self-interest, or do individuals also value direct democracy as such, regardless of the material payoffs associated with anticipated policy outcomes? To answer this question, we use a survey data set that offers information on respondents’ support for referendums as a procedure to decide on tax policy, their income levels, socio-economic characteristics, and, most importantly, their expectation about the majority’s support for higher taxes. We find that the support of low-income individuals for referendums increases substantially if they expect a clear population majority in favor of more redistribution. Conversely, individuals with a high income who expect a majority in favor of higher taxes do not reject referendums more strongly than individuals with an average income who share these expectations.  相似文献

With the growth of multi-channel retailing, many firms that have traditionally relied upon third-party service providers to offer after-sales service (AS) have introduced direct AS channel. While there exist a few studies that examine the effects of adding a direct sales channel on the sales revenue of incumbent channels, there are no studies investigating the effects of adding direct AS channel. This study tries to fill this research gap by exploring cross-channel effects of including AS through the firm's direct brand stores on performance (i.e., revenue, assortment width, and extent of upselling) in both direct and indirect channels. A matched difference-in-difference quasi-experimental design was used to compare the sales outcomes of test and control groups using a five-year longitudinal dataset from a large dual-channel consumer durables firm. Results reveal that providing AS through the firm's direct channel has a positive significant effect on the revenue and upselling in the indirect channel, but no significant impact on assortment width in the indirect channel. However, unlike hypothesized, it results in significantly lower revenue, assortment width, and upselling in the direct channel. We interpret these negative effects as arising from customer confusion and perceived retail crowding. Overall, our research highlights that implementation of going direct with AS should be done with utmost care. Our findings would serve as a building block for future studies that are conducted to understand the dynamic cross-channel effects of introducing direct AS, and would be useful for drawing comparisons and contrasts.  相似文献
