论本币升值对国内物价的影响路径

本币升值可通过实体经济、虚拟经济以及货币政策三个途径影响一国的国内价格;本币升值通过国内物价影响经济稳定存在一个正反馈机制;从短期来看,人民币升值不仅不能抑制国内物价上涨,还可能推动国内物价的上涨。     

Design concept for the solid waste landfill site： a case study of Chuzhou City, China

1. Introduction Domestic waste has become a worldwide hazard. It has been listed in Preferential Programmes in China for 21st Century. The combination of the three techniques, the transformation of domestic waste into useful resources, the reduction of do- mestic waste and the innocent treatment of domes- tic waste is the long-term guideline in China. In the spirit of the guideline, several laws and regulations have been enacted, including Technical Standards of Municipal Solid Landfill, …     

Drivers and barriers to cross-border e-commerce: Evidence from Spanish individual behavior

This paper explores the determinants of the individual's decision to perform cross-border e-commerce (CBeC). The European Union (EU) is especially interested in the promotion of CBeC because it is an important tool in its strategy to achieve the Digital Single Market in Europe. In this paper official data is used from a representative survey of 16,209 individuals on ICT usage by households and individuals that was carried out in Spain by the National Institute of Statistics (INE) for the year 2016. Using a standard neoclassical utility maximization framework, and logistic regression techniques, the results show that being a male is positively related to the probability of practicing CBeC. Education is positively and significantly related to the probability of being involved in CBeC with EU countries. Computer and Internet Skills are significant and positive factors in explaining CBeC (either with EU countries or with the rest of the world). The variable “how often the consumer sees other customer reviews before buying online”, has a positive effect. Foreign nationality also increases the likelihood of using CBeC. To promote CBeC in Spain measures towards developing digital skills, Internet trust and use of online information reviews of goods and services are discussed.     

互联网化对中国企业出口国内增加值提升的影响

本文大量研究讨论了企业出口增加值的影响因素。我们基于Melitz(2003)模型,对企业互联网化进行了扩展,认为随着企业互联网化程度的提高,企业会更多地使用国内中间投入。基于中国海关数据库、中国工业企业数据库以及新浪微博的数据匹配,研究表明:(1)从贸易方式来看,企业互联网化程度的提高有助于提升一般贸易企业的出口国内增加值率;(2)区分企业所有制、所在省域和企业出口持续时间,发现企业增强互联网化程度对提升国内中间投入使用的促进作用会因企业所有制、所在省域和参与全球生产网络稳定性的不同而异,互联网化对非国有企业、东部省份企业和持续出口企业的促进作用更加显著;(3)中介效应检验结果显示,企业互联网化主要通过提高国内中间投入的使用这一渠道提升了中国企业出口国内增加值率。据此,在数字经济背景下,企业通过加强自身业务同互联网的融合,提高了国内中间投入的使用,有助于提升本国企业出口竞争力。     

金融危机以来我国沿海港口货物吞吐量影响因素研究——兼论我国经济由外需拉动向内需驱动转型的一个证据

通过建立基于贸易引力模型的我国沿海港口货物吞吐量影响因素的VAR模型,分别考察了交通运输业固定投资、人民币汇率、世界经济状况和国内经济状况对我国沿海港口货物吞吐量的影响,并以金融危机以来的数据作为样本对该模型进行了实证检验。由脉冲响应和方差分解分析发现:世界经济发展状况对我国沿海港口货物吞吐量的影响最大,且世界经济的复苏将显著提高沿海港口货物吞吐量;交通运输业固定投资在经过一个滞后期后,也会对沿海港口货物吞吐量起到积极的作用;人民币汇率对我国沿海港口货物吞吐量的影响不可忽略,且汇率上升(即本币贬值)将提高沿海港口货物吞吐量;而国内经济发展状况则与我国沿海港口货物吞吐量之间并不存在显著的确定关系,这或表明我国经济的发展方式正由外需拉动向内需驱动转型。     

对外直接投资促进了出口国内附加值率提升吗

针对企业对外直接投资是否提升了企业出口国内附加值率的问题,利用倾向得分匹配法为2004~2007年386家对外直接投资企业找到与其可比较的对照组,运用倍差法检验了对外直接投资对企业出口国内附加值率的影响效应。研究发现:企业对外直接投资显著提升了企业的出口国内附加值率,且这种促进作用随着时间的推移逐渐增强;投资动机、投资目的国的发展水平对出口国内附加值率的促进效应存在差异性;在使用不同的估计方法和替换核心被解释变量进行检验后,结论依然稳健。     

Modelling interactions among the housing market and key US sectors

This study evaluates the dynamic interactions among the housing market and ten key US sectors including: consumer discretionary, consumer staples, energy, financials, industrial, technology, health care, materials, utility and telecommunications. Long-run results indicate that the housing market is integrated with each of the ten sector and that the degree of convergence has increased over time and especially after the onset of the most recent housing crisis. Moreover, the housing market contributes most heavily to the common trends indicating that the housing market is the ‘leader’ market that drives each sector towards the long-run equilibrium relationships. Short-run analyses indicate causal linkages emanating from the housing market to each sector with reciprocal feedback. Finally, impulse response function analysis reveal that shocks from each sector affect the housing market but that shocks from the housing market have a (comparatively) more profound and persistent impact on each sector.

外商直接投资对东道国国内投资的“挤入”与“挤出”效应——来自中国数据的经验证据

本文根据中国1979-2009年的数据,对FDI与中国国内投资之间的关系进行了分析。研究结果表明,FDI与国内投资之间存在着长期稳定的均衡关系;从长期来看,FDI对于国内投资具有一定的挤出效应;而在短期内,FDI对国内投资具有较强的挤入效应,国内投资对FDI也具有较强的挤入效应。     

Using partial identification methods to estimate the effect of violence against women on their children’s health outcomes

A growing literature in economics seeks to estimate the costs of violence against women by examining, for example, its impact on the health outcomes of their children. However, it is difficult to assign a causal interpretation to these nonexperimental studies due to the presence of unobservable characteristics affecting violence and health outcomes simultaneously. The lack of credible instrumental variables applicable in several countries further limits our knowledge. I address this gap by using new partial identification methods to estimate the relative size of the unobservables needed to eliminate the estimated effects in nonexperimental studies. I also expand the external validity of the analysis by using data from five standardized nationally representative household surveys in Latin America. Consistent with previous studies, cross-sectional estimates show large negative associations between violence against women and an array of child health outcomes. However, when accounting for omitted variable bias, at best, two-thirds of the estimates remain robust and they are concentrated on the outcomes with the largest cross-sectional estimated impacts.
