产业链下游企业转型升级影响因素研究——基于不同最终产品市场的视角

在国际竞争加剧和国内工业经济放缓的背景下,中国制造业企业生存压力日益加剧,制造业企业如何转变发展方式、实现转型升级,值得深入研究。本文通过构建寡头博弈模型,发现处于产业链下游的一国企业,在面对国外垂直一体化的企业的竞争时,实现转型升级所需掌握的核心技术水平受到最终产品市场类型、最终产品相对质量以及最终产品差异化程度等多种因素的影响。此外,最终产品市场类型还会影响最优研发政策的稳健性：最终产品市场位于国外时,政府不应对企业研发行为进行干预;而当最终产品市场位于国内时,实施研发补贴政策不仅会促进社会福祉,而且可以促进企业转型升级。     

语言能力和语言应用理论在大学英语分层教学中的运用

由于当今大学生英语水平存在着差距,我们应该对不同水平的学生实施相应的教学方法。其中,在大学英语分层教学中如何处理一语言能力和语言应用的比例是非常重要的。     

FDI in China and global production networks: Assessing the role of and impact on big world players

How can countries successfully engage in global production networks? We provide a Computable General Equilibrium analysis of the impact of FDI on global production networks in Textiles, Chemicals, Electronics and Machinery, dividing the world economy in six regions (China, East Asia, Japan, EU28, the U.S. and the group of Emerging and Developing Economies). Interestingly for the policy maker, although the four sectors have contrasting production technologies, their Chinese exports and imports still follow a similar trend: East Asia and Japan are Chinese main intermediate suppliers while the US, Europe and the Emerging and Developing Economies play more the role of final markets. FDI inflows have benefitted China and we quantify by how much they have raised Chinese wages, GDP, national income and export competitiveness. By contrast, being an intermediate supplier or playing mostly the role of big final market in the network is not enough to succeed in your integration with China. The extent of the (positive or negative) effects is very much related to whether the structure of production (i.e., sectors’ weight in GDP) of the different economies is similar to (and therefore more easily crowded out by) Chinese booming sectors.
