A Study on China’s Export Diversification Evolution Determinants and Its Economic Growth Effect

出口作为拉动国家经济增长的三架马车之一，对一国的经济增长发挥了举足轻重的作用。一些国家通过出口导向型的战略摆脱了贫困，并创造了经济增长的奇迹。但是如果一国仅仅注重出口的扩张，而不注重对出口商品结构的转变，出口贸易的增长并不会给一国经济带来持续稳定的增长。如，一些国家凭借其丰富的自然资源出口初级产品，最终却陷入了贫困化增长的陷阱，还有一些国家通过出口多样化的商品，实现了经济的腾飞。如今，出口多样化已成为许多发展中国家拉动经济增长的战略选择。 中国作为发展中的大国，在深度融入经济全球化过程中，面临经济新常态下实施出口多样化战略具有重要的意义。本文基于中国出口贸易和经济发展水平的客观事实，重点分析...Export is very important to a country’s economic growth. Some countries got rid of poverty by export-oriented strategy and created the economic growth miracle. If a country only pays attention to export expansion, but does not pay attention to the change of export commodity structure, the country will not get a sustained and stable economic growth. Some countries which had rich natural resources f...学位：经济学博士院系专业：经济学院_国际贸易学学号：1572012015361

Does Agglomeration Upgrade Export Diversification?: An Empirical Analysis Based on China's Provincial Panel Data

基于地区工业行业集聚的视角,提出相关多样性和非相关多样性对地区出口多样化影响的理论假说,采用我国1999~2009年期间30个省(市)的样本数据进行实证检验。研究结果表明,相关多样性工业行业集聚对地区出口多样化影响不显著,但是在人力资本的推动作用下,相关多样性工业行业集聚对地区出口多样化的发展具有显著的促进作用;非相关多样性工业行业集聚则更有利于地区出口专业化的发展。This paper proposes the theoretical hypothesis that there exists the impact of related variety and unrelated variety on export diversification in the perspective of regional industry agglomeration.This paper makes an empirical test by using China's 30 provincial level sample data during 1999~2009, and shows that the agglomeration of related variety industry does not have a significant effect on regional export diversification, but the agglomeration of related variety industry has a significant effect on promoting the development of regional export diversification; the agglomeration of unrelated variety industry has a positive role on promoting regional export specialization

The Evolution of China's Export Diversification and Its Determinants:an Empirical Analysis Based on Provincial Panel Dada

基于出口产品的泰尔指数及其新的分解方法,分析了中国国家层面和地区层面出口多样化的演变,探讨了出口多样化的“集约边际“和“扩展边际“问题,揭示了中国出口多样化演进的特征事实。分析表明,从国家层面来看,中国出口产品仍处于多样化的发展阶段,并呈现出收敛的发展态势,同时出口多样化的“扩展边际“占据主导地位;从地区层面来看,东部地区的出口多样化水平要高于中西部地区,东部地区的出口多样化以“扩展边际“为主,而中西部地区的出口多样化则以“集约边际“为主。基于1998-2009年的省际面板数据,对中国出口多样化的影响因素进行实证检验。研究发现,人力资本、国内市场规模、固定资产投资和贸易开放度等因素有利于中国出口多样化的发展。Based on Theil index of export products and its new method of decomposition,this paper analyzes the evolution of China's export diversification from the aspects of country and region and explores the"intensive margin"and "extensive margin"of export diversification to reveal the stylized facts of the evolution of China's export diversification.The results show that in the aspect of country,China is on the development stage of export diversification and it shows the trend of convergence,and China's "extensive margin"of export diversification occupies a dominant position;in the aspect of region,the export diversification of eastern China is higher than central and western China,and the export diversification of eastern China is mainly composed of "extensive margin"and the export diversification of central and western China is mainly composed of"intensive margin".Using provincial panel data during 1998—2009,this paper makes an empirical test on the determinants of China's export diversification.We find that human capital,domestic market scale,fixed assets investment and trade openness also contribute positively to the development of China's export diversification

This study uses the semi-parametric regression model to analyze provincial panel data from 1998 to 2009, and looks into the effect of export diversification on China's economic growth. Our results show that export diversification promotes China's economic growth, and that this effect results mainly from the effect of “intensive margin” of export diversification on economic growth. However, the effect of “extensive marginal” of export diversification on China's economic growth is not significant. Judging by the current economic development in China it can be asserted that China has not reached the “turning point” which marks a transformation from export diversification to export specification. There is still considerable room for China to develop her export diversification. It is suggested that we should further enhance the level of China's export diversification by deepening the “intensive margin” of export diversification and expanding the “extensive margin” of export diversification thereby maximizing the effect of export diversification on China's economic growth.教育部哲学社会科学研究重大课题攻关项目“要素成本上升背景下我国外贸中长期趋势研究”(13JZD010)；中央高校基本科研业务费专项资金资助“中国经济增长的出口驱动力问题研究”（T2013221017

Study on adsorption dsorption and oxidation of 1,4-butanediol at Pt and modified Pt electrodes

　运用电化学循环伏安和石英晶体微天平研究了1,4-丁二醇(1,4-BDL)在Pt电极及以Sb和S吸附原子修饰的Pt(Pt/Sbad和Pt/Sad)电极上的吸附和氧化过程.结果表明,1,4-丁二醇的氧化与电极表面氧物种有着极其密切的关系,表面质量变化提供了吸附原子电催化作用的新数据.Pt电极表面Sb吸附原子能在较低的电位下吸附氧,可显著提高1,4-丁二醇电催化氧化活性.与Pt电极相比,1,4-丁二醇在饱和吸附Sb原子的Pt电极上氧化的峰电位负移了0 20V,峰电流增加了1 5倍.相反,Pt电极表面S吸附原子的氧化会消耗表面氧物种,饱和吸附的S原子抑制了1,4-丁二醇的氧化.The processes of adsorption and oxidation of 1,4-butanediol on Pt,Pt/Sbad and Pt/Sad electrodes were studied by using cyclic voltammetry and electrochemical quartz crystal microbalance(EQCM).The results demonstrated that the oxidation of 1,4-butanediol depends strongly on oxidation states of electrode surface.Sb adatoms on Pt surface can adsorb oxygen at relatively low potentials,and exhibit catalytic effects for 1,4-butanediol oxidation.In comparison with the case of Pt electrode,the oxidation peak potential of 1,4-butanedion on Pt surface modified with Sb was negatively shifted about 200 mV and the peak current was increased.On a contrary,the oxidation of S adatoms consumes oxygen species of Pt electrode surface.As a consequence,the oxidation of 1,4-butanediol was inhibited by the presence of Sad.The EQCM studies provided quantitative results of surface mass variation during 1,4-butanediol oxidation,and have thrown new light on elucidating different effects of adatoms Sbad and Sad on Pt electrode towards 1,4-butanediol oxidation.国家自然科学基金资助项目(29833060);; 福建省教委科研基金资助项目(K2001101)
