金融发展与城乡收入分配的“库兹涅茨效应”研究

中国当前的金融发展规模显著拉大城乡收入差距.加强农业贷款对农民收入增长具有显著作用,会缩小城乡收入差距.金融发展效率的提高有助于城乡收入差距的缩小,在金融发展和收入差距之间存在库兹涅茨效应.金融发展水平与城乡收入分配之间存在长期的均衡关系.金融发展规模、农村信贷与城乡收入分配之间存在单向因果关系,金融发展效率与城乡收入分配之问存在双向因果关系.     

长阳县发展旅游业与农民增收的关系研究

农民增收是新农村建设的一项重要任务,要从根本上解决农民增收问题,关键在于把农村剩余劳动力转移出来。在对湖北宜昌长阳土家族自治县的调研中发现,旅游业可以有效地实现劳动力的转移,走＂进厂不进城、离土不离乡＂的发展道路,使旅游业的发展与农民增收相得益彰。     

"两税"并轨对我国引进外国直接投资的影响

由于目前我国来自香港、台湾地区的直接投资以及一些国际避税地的外国直接投资占绝大多数,已将近总额的60%,因此,提高外资企业所得税率很可能会导致大量外资流向周边低税国家,从而对我国引进外资的总量产生较大影响。所以我们对税收优惠的调整在时间上和优惠方式的取舍上,都应有一个平稳的过渡,使我国对外开放和引进外资的政策保持延续性。     

The Long‐Run History of Income Inequality in Denmark

We use historical publications and micro data from tax returns to construct internationally comparable estimates of the development in income inequality in Denmark over the last 140 years. The study shows that income inequality and top income shares have declined during several distinct phases in between periods of stability. Furthermore, the quality of the Danish data allows us to analyse not only the development in top income shares but also broader inequality measures such as the Gini coefficient. These analyses show that top income shares are a good proxy for the underlying development in inequality.     

金融发展与城乡收入分配的库兹涅茨效应研究——基于中国省级面板数据的检验

金融发展可度量为金融-规模、金融-活动和金融*效率三个主要指标.利用OLS和GMM回归、面板单位根、协整和因果关系检验对中国金融发展水平与城乡收入分配之间的关系进行检验后得知: (1)金融发展和城乡收入差距之间存在着库兹涅茨效应,即所谓的倒U关系. (2)中国金融发展规模显著拉大了城乡收入差距,但加强农业贷款对农民收入增长取得了显著作用,会缩小城乡收入差距;金融发展效率的提高有助于城乡收入差距的缩小. (3)金融发展水平与城乡收入分配之间存在长期的均衡关系;金融发展规模、农村信贷与城乡收入分配之间存在单向因果关系,金融发展效率与城乡收入分配之间存在双向因果关系.     

Investigating the Impact of Income on Savings Using a Chinese Household Level Dataset

This article uses the China Household Financial Survey (CHFS) to examine the savings behavior of Chinese Households. Using a standard cross-sectional empirical approach to modeling permanent and transitory income, we show that one way of explaining the relative high savings rate in China is by recognizing that in fast growing economies, individuals may have higher transitory income from which they save a large proportion. The estimation also contains a range of household specific variables which can be used to understand the impact of socio-economic characteristics such as urban vs rural dwelling, age, and the educational level.     

中国城市居民收入和储蓄增长对家庭能耗碳排放的区域异质性及政策应对

估计和预测城市居民收入变化对家庭能源消费碳排放的影响,对城市家庭消费部门构建低碳能源供应体系,应对气候变化具有重要意义。论文首先估计了中国284个地级以上城市的家庭三类能源消费的直接碳排放量,建立了面板固定效应模型来识别城市家庭能耗碳排放增长和变化的驱动因素。研究结果表明:城市居民收入的快速增长与储蓄水平的提高对于家庭碳排放有显著影响;城市家庭收入和储蓄的增加会抑制家庭燃气碳排放的产生,但对于城市家庭用电碳排放和城市家庭采暖碳排放,则表现出显著的推动作用。此外,研究还发现了家庭碳排放的影响因素存在显著的区域异质性。     

我国收入差距扩大的影响因素及其实证分析——以行业收入变动为视角

笔者以传统行业收入决定理论为基础,运用2003年～2008年我国19个行业的面板数据构建模型,系统地分析了2002年至今各行业收入变动的影响因素及其影响效果.结果表明,生产效率仍然是决定收入变动的重要因素;垄断因素在行业收入差距扩大中扮演最重要的角色;人力资本水平对收入变动的作用有待于进一步提升.笔者还阐述了加入"世贸"组织后垄断行业暴利、高教扩招等社会现实问题对行业收入变动的影响.     

A Proposal to Compare Consistently the Inequality Among the Poor

A poverty index should be sensitive to the number of poor people, the extent of the shortfall of the poor, and the inequality among the poor. A difficulty arises when inequality among the poor needs to be assessed. The inequality may be analyzed in terms of either incomes or gaps. Depending on what side we focus on, the inequality level comparisons may be contradictory. This paper proposes a reinterpretation of the inequality component involved in the decompositions of well‐known poverty indices. The alternative indices we introduce measure equally the income and gap inequality among the poor. The comparisons in inequality as measured by these indices are then independent of the viewpoint. An empirical application illustrates the proposal.     

收入因素与中国劣质品市场的部分逆向选择

基于Akerlof逆向选择模型,引入收入因素对其分析,通过说明收入因素影响消费偏好,进而改变消费者的无差异曲线,建立一个有限次交易后最终达到非零均衡的部分逆向选择的基本模型,并着重从这一侧面,即收入因素的影响,分析为什么在中国劣质品市场会长期存在。研究表明：购买偏好因收入增加而改变明显的劣质品的解决途径是增加人们的收入水平;购买偏好随收入增加改变不明显的劣质品的解决途径是增加外部干预。
