中南五省流通业的发展和经济增长相关性分析——基于面板协整、因果检验方法

本文利用面板协整检验、格兰杰因果检验模型,对中南五省的国内生产总值、批发零售和餐饮业之间的协整、格兰杰因果关系进行检验,研究结果表明：国内生产总值和批发零售、国内生产总值和餐饮业之间存在长期稳定的协整关系;各省的餐饮业、批发零售业对GDP的增长存在显著的促进作用,并且促进程度在各省之间存在明显的差异,其中沿海两省远远高于内地三省;地理位置的空间差异对餐饮业、批发零售业对GDP的长期影响程度存在明显性影响。中南五省整体的面板协整方程估计结果同样表明,批发零售业和餐饮业的发展,促进了各省GDP的增长。     

金融开放背景下金融发展对跨境资本流动的影响研究

金融开放能够促进跨境资本流动,也具有引发跨境资本流动失衡和波动性增加的风险,而一国金融发展水平在其金融开放效应中发挥着重要作用。本文基于58个国家及地区1999-2016年的数据建立动态面板模型,研究金融开放背景下金融发展对直接投资和证券投资流入、流出以及总跨境资本流动波动性的影响。研究结果表明:金融开放本身有可能造成跨境资本流出大于流入的失衡现象,并显著增加跨境资本流动波动性风险,而金融发展水平的提高有助于在一定程度上抑制金融开放带来的跨境资本流动失衡现象和波动性风险。因此,在扩大金融开放进程中,为获得跨境资本流动的积极效应,应密切关注跨境资本流向和资本波动性变化,提高国内金融发展水平,使之与金融开放水平相匹配。     

美国金融危机对中国出口贸易的影响

本文选取中国与G7国家双边贸易数据,构建动态面板数据模型,实证分析了美国金融危机对中国出口贸易的影响。结果表明,美国金融危机导致G7国家经济陷入衰退,失业率上升、金融市场动荡和国内需求萎缩,由此带来的贸易传播效应给中国出口贸易带来了较为严重的负面影响。从具体的传递渠道来看,G7国家实际GDP指数下降、股票价格指数下跌和人民币实际汇率的波动对中国出口贸易的负面影响较为显著;而G7国家失业率增加对中国出口贸易的影响较小且并不显著。     

FDI引进质量对我国技术溢出效应的影响

通过对2002～2007年间的地区和工业行业的面板数据进行估计,结果显示:在2002～2007年间,FDI对我国三大区域和工业行业内部有正的技术外溢,但中部地区和劳动密集型行业获得了更大的技术外溢效应。因此,今后东部地区工业行业的引资应偏重技术差距较大的资本、技术密集型行业,中、西部地区暂时仍应以劳动密集型行业外资的引进为主。     

新兴经济体FDI流入的决定因素及中国的应对策略

吸引FDI流入是新兴经济体促进经济发展的重要手段,但FDI活动深受东道国区位因素的广泛影响。利用1995-2009年的面板数据,对新兴经济体吸引FDI流入的决定因素进行实证分析,结果表明:FDI与东道国聚集效应、市场规模、基础设施、资源禀赋、经济开放度显著正相关,但与东道国人力资本和政治风险负相关。因此,中国应该强化FDI的区域聚集效应、行业聚集效应和特定投资来源地聚集效应,保持经济稳定、持续的增长,加大对落后地区的基础设施建设的投入,构建全方位的对外开放体系和引资战略,实现经济持续快速发展。     

Assessing market power in the U.S. commercial banking industry under deregulation

This study attempts to investigate market power in the U.S. commercial banking industry since the U.S. government began to deregulate the banking sector in the early 1990s using the static Bresnahan–Lau model (SBLM) and dynamic Bresnahan–Lau model with error corrections (DBLEC). In particular, panel unit root and panel cointegration techniques are utilized to examine the dynamic model. The empirical results of the SBLM show that the banking industry is highly competitive. The empirical results of DBLEC also suggest that the commercial banking industry is close to being perfectly competitive in the short run. By contrast, the adjustment speeds of the supply and demand sides towards the long-run equilibrium are quite slow in that market, which implies that the U.S. commercial banks enjoy a certain degree of long-run market power.     

Introducing errors in progress ratios determined from experience curves

Progress ratios (PRs) derived from historical data in experience curves are used for forecasting development of many technologies as a means to model endogenous technical change in for instance climate–economy models. These forecasts are highly sensitive to uncertainties in the progress ratio. As a progress ratio is determined from fitting data, a coefficient of determination R² is frequently used to show the quality of the fit and accuracy of PR. Although this is instructive, we recommend using the error σ_PR in PR, which can be directly determined from fitting the data. In this paper we illustrate this approach for three renewable energy technologies, i.e., wind energy, bio-ethanol, and photovoltaics.     

Cross sectional and panel estimation of convergence

Cross sectional estimation of convergence regressions is known to be hazardous if there is convergence towards heterogeneous steady state values. In this paper, Monte Carlo methods are used to investigate the implications of this parameter heterogeneity problem. The cross sectional and pooled OLS estimators are compared with a panel estimator which is unaffected by heterogeneity. If there is heterogeneity, the latter outperforms both the unconditional and conditional cross sectional and pooled OLS estimators.     

Enlarging the EMU to the east: what effects on trade?

The purpose of this article is to assess the implications of the Economic and Monetary Union (EMU) accession of eight Central and Eastern European Countries (CEECs) on their share of EMU-12 imports. Overcoming biases related to endogeneity, omitted variables and sample selection, our results indicate that the common currency has boosted intra-EMU imports by 7%. Under the assumption that the same relationship between the explanatory variables and imports will hold for EMU-CEEC trade, we intend to predict the future impact of the Euro. Our findings suggest that except for the least integrated countries, Poland, Latvia and Lithuania, all CEECs can expect increases in the EMU-12 import share.

FDI与中国二元经济结构演化——一个动态实证分析的考量

FDI理论和二元经济结构理论一直以来都是国内外主流经济学者研究的热点问题。但是从理论上和实证角度把二者结合起来研究的文献并不多见。为此,本文首先从古典增长理论模型出发,论述FDI对我国二元经济结构演化的影响,理论模型研究表明,FDI在促进中国经济非农化的过程中有可能加大了农业与非农业的技术与就业差距,从而加深了二元经济程度。然后重点从实证角度、运用统计分析和因果关系检验、协整检验及修正误差模型检验等计量分析手段深入研究和检验二者的长期与短期动态均衡关系。研究结果表明,FDI在促进中国经济非农化和工业化的同时,在一定程度上却加剧了中国的二元经济程度。对此,本文在最后强调应该加大对FDI的产业调整力度、规范其投资流向,同时建立一套长效机制,实现农村生产要素的市场化与整合,充分挖掘FDI在转变农业生产方式方面的潜在作用,缩小农业与城市部门生产效率的差距。
