复合超声振动游离磨料抛光技术及其实验研究

本文针对超光滑表面的需求,提出了一种游离磨料振动强化抛光加工方法,该抛光方法以游离磨料作为介质,在抛光过程中加以超声空化作用的辅助,加上工件的高速振动,使流体分子或微细磨拳斗粒子能不断冲击工件表面,从而获得超光滑表面。进行了相关实验,并得出了一系列结论。     

Transatlantic Trade and Investment Partnership and Trans‐Pacific Partnership: Policy Options of China

As a result of deadlocked multilateral trade negotiations, many countries have embarked on the establishment of bilateral and regional trade agreements. Using the Global Trade Analysis Project database and a computable general equilibrium model, our paper focuses on the impacts of the Transatlantic Trade and Investment Partnership (TTIP) and the Trans‐Pacific Partnership (TPP) on the Chinese economy under three scenarios. The results suggest that when only the TTIP is realized, Chinese economic variables are negatively affected. When both the TTIP and the TPP are realized and China is excluded, the combined damage to the Chinese economy is higher than the damage with the TTIP alone. However, the inclusion of China in the TPP has a positively effect on economic variables in China. This indicates that the impacts of China's participation in the TPP compensate for the negative impacts of the TTIP. Therefore, China should consider being part of the TPP to offset the negative impacts of the TTIP.     

Impact of Cross-Strait Trade Liberalization： A Computable General Equilibrium Analysis

This paper applies a computable general equilibrium model to investigate the potential economic effects of trade liberalization across the Taiwan Strait. Our simulation results reveal that cross-Strait trade liberalization will have significant positive impacts on external trade, domestic investment and real GDP for the economies in this area in general and in Taiwan in particular. Furthermore, the negative impact from the formation of a free trade arrangement between Taiwan and Chinese Mainland on Hong Kong seems to be rather small. These results suggest that cross-Strait trade liberalization is very likely to bring about a win-win situation for the economies in this area.     

自由现金流量、并购溢价与我国上市公司并购绩效的实证研究

国内外的研究结果表明高自由现金流量低成长性公司在并购后绩效会出现明显的下滑,并把绩效下滑归因于代理成本。文章力图在自由现金流量与并购绩效之间搭建一座桥梁,深入分析导致并购绩效下滑的直接客观原因。通过利用我国上市公司2001-2003年436次并购事件进行实证分析的结果表明,支付过高的并购溢价是导致高自由现金流量低成长性上市公司并购绩效低下的直接客观原因。

中国--东盟自由贸易区建构的地缘分析

中国与东盟在21世纪之初决定携手建构自由贸易区,其原因是多方面的。其地缘上的邻近在这一过程中发挥着重要的作用,地理位置至关重要地影响着国家的战略选择。中国与东盟在经济地缘、政治地缘和人文地缘上的相连相近,为中国—东盟自由贸易区的建构提供了良好的条件,并成为中国与东盟决定建立自由贸易区的重要动力。     

Would a North-South Free Trade Agreement Hurt Unskilled Labor in the North?

I present a simple model to examine the impact of international outsourcing on the welfare of skilled and unskilled labor. In this model, specialized business services are to facilitate manufacturing production, creating additional welfare gains in the presence of positive production externalities. Policies that favor the business service sector contribute to the development of a larger bundle of specialized business services, generating more welfare gains to not only skilled but also unskilled labor. Thus, a country’s unskilled labor is not necessarily worse off with open trade if the country is prosperous in business service provisions.     

保卫民族产业与内向型经济:中国崛起的唯一选择

历史经验说明,保护主义和内向型经济是发展中大国经济崛起的必由之路。英国通过保护主义造就了产业革命的辉煌,美国通过典型的内向型经济实现了对英国的赶超。那种把保护主义看作是落后的代名词,认为保护主义无法解决技术进步问题并导致企业不能承受国际竞争的看法与历史经验大相径庭。我国以自由贸易、加入全球产业价值链和依赖外国直接投资为核心的出口导向型经济发展模式是目前我国经济陷入诸多经济困境的主要根源,这使我们不得不重新认识保护主义和内向型经济发展战略的基本经济学原理。为了从目前的经济困局中突围出来,并重新开启中国经济崛起之路,提出了保卫民族产业,实现中国经济崛起的十大战略方针。

“三元悖论”与中国汇率制度选择

＂三元悖论＂的基本原理是指在货币政策独立、资本自由流动和固定汇率这三个经济目标中最多只能同时实现两个,而该理论本身也存在理论假设过于绝对化,组合难以有效实现,政策组合难以执行的局限性。基于对中国资本流动现状和货币政策有效性分析和＂三元悖论＂的基本原理分析,得出我国的汇率制度选择终级目标是实现＂货币政策独立＋资本自由流动＋自由浮动汇率＂的政策组合。
