经济全球化背景下的我国税制改革

随着改革步伐的加快,尤其是我国于2001年12月11日正式成为WTO一员之后,我国经济的发展与世界经济更加紧密联系在一起,到了“你中有我,我中有你”,谁也离不开谁的地步。与此同时也对我国社会经济各个领域产生了巨大的冲击,在这种趋势下,必然要求革除原有税收体制弊端,建立一种与国际税收政策相协调的税收制度,以促进我国经济的进一步发展。     

经济增长的变化本质

在过去的一个世纪中,富裕国家的经济本质已经发生了巨大的变化。因此,文章提出“技术生理演变(technophysio evolution)”概念,即快速技术变化和人类生理进步的协同作用。这主要表现在以下三个方面：(1)消费结构和工作体闲时间分配的改变;(2)经济和家庭产出分配方面受高水平经济成就的影响;(3)全球市场迅速急剧转向耐用消费品和高科技服务。

Can Insurance Activity Act as a Stimulus of Economic Growth? Evidence from Time-Varying Causality in China

This article investigates the nexus between insurance and economic growth in China with a dynamic interactive mechanism to study different time periods. Using quarterly data from 1999 to 2015, the rolling-window causality test provides evidence of bidirectional causality between insurance activity and economic growth. However, the “supply-leading” pattern tends to dominate the “demand-following” pattern, which implies that in China insurance acts as a stimulus of economic growth during most of the period. Property insurance is more effective than life insurance in stimulating economic growth. Some temporary negative impacts from the development of the insurance sector show that China is in the midst of a transition from a closed economy to a more open economy and policy interventions by the government to liberalize the insurance sector. These findings offer several useful insights for policy makers in transition economies and developing countries.     

Does the Connectivity of the Belt and Road Initiative Contribute to the Economic Growth of the Belt and Road Countries?

ABSTRACT

Since the Belt and Road Initiative (BRI) has been implemented for five years, it is time to ask whether the BRI contributes to Belt and Road (BR) countries’ economic growth, and how are the five elements of connectivity implemented between China and its partner countries since the BRI was proposed. This study focuses on the development of the five elements of connectivity between China and the BR countries from 2008 to 2017 using a comprehensive connectivity index extracted from principle component analysis, and then investigating if the connectivity has contributed to the economic growth of the BR countries with quantitative analysis of the fixed effect econometrical model. It is found that Russia, South Korea, and Singapore presented the top three levels of connectivity with China with regard to the overall connectivity index, varying from 1.4 to 2.4. Madagascar and Panama have the lowest level of connectivity with China, with values of ?0.8 to ?1.1. The result of the fixed effect model shows that the connectivity of the BR countries with China contributes to their economic growth. This provides quantitative evidence that the connectivity between BR countries and China has a significant influence on the economic growth of those countries.

循环经济:生态文明的基本经济形态

循环经济是一种经济形态而非循环技术,是为解决无限的人类欲望与有限的资源环境矛盾的基本经济活动;循环经济是对市场经济的兼容而非取代,因为市场经济存在循环经济成长的基因,是市场经济发展的更高阶段;循环经济可以孕育出生态文明,后工业文明的经济形态既不是自给自足经济,也不是计划经济;与低碳经济、绿色经济、生态经济、可持续发展经济相比,循环经济立意高远、简单明了、系统全面、指向明确、包容性强,是生态文明的基本经济形态。     

经济增长、收入分配对农村贫困变动的影响

文章利用了基于Lorenz曲线进行贫困测度及其分解的方法,实证研究了1985～2003年中国农村的贫困变动,以及经济增长和收入分配对贫困变动的影响.结果表明,经济增长使农村居民收入增加,大幅度减少了贫困,但农村居民的收入差距逐渐拉大,收入不平等加剧部分地抵消了经济增长的减贫成效.
