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。     

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。     

收入、收入类别与环境库兹涅茨曲线

利用2000-2009年我国省际面板数据,对人均收入、收入类别与六种污染指标之间的关系进行了实证检验.结果表明:环境库兹涅茨倒U型关系取决于污染指标的选择,在样本期内,部分污染指标呈现出倒U型EKC关系;在倒U型曲线的转折点处,城镇人均可支配收入的临界水平高于农村人均纯收入的临界水平.     

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.

双边投资协定对发展中国家吸引FDI的影响——基于面板数据的实证研究

由于国际直接投资有利于促进东道国的经济发展,发展中国家越来越多地通过签署双边投资协定(BIT)来吸引FDI,但BIT在吸引FDI方面的有效性值得检验。本文基于47个发展中国家的双边投资协定和国际直接投资数据,利用STATA10.0计量软件,采用面板数据模型分析了BIT对发展中国家吸引FDI的影响,同时,为了更全面研究BIT对吸引FDI的影响,还考察了BIT与制度质量、单边投资自由化之间的关系,结果显示BIT有利于发展中国家FDI流入的增长,且与制度质量、单边投资自由化之间存在替代关系。     

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.     

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。     

所有制结构变迁影响城乡收入差距的实证检验——基于面板协整的方法

所有制结构变迁是居民收入差距的根本原因,利用1995-2008年30个地区的数据进行面板协整检验表明：国有经济、集体经济与城乡收入差距存在协整关系,公有制经济和非公有制经济分别与城乡收入差距也存在协整关系;国有经济、公有制经济能缩小城乡收入的差距,而集体经济和非公有制经济则扩大城乡收入的差距。     

Analyzing air cargo flows of international routes: an empirical study of Taiwan Taoyuan International Airport

Air cargo demand is an important aspect of the operation and planning of private and public agencies responsible for airports. While most existing studies in this field include only geo-economic characteristics of airports and their hinterlands as explanatory variables, this study develops a gravity model of air cargo flows by trying to incorporate more factors that might influence international air cargo flows of an airport. The model is developed based on the panel data of air cargo services on scheduled routes at Taiwan Taoyuan International Airport during the years 2004-2007. The results indicate that population, air freight rate and three dummy variables, including the regional economic bloc of the “Chinese Circle”(an informal partnership between Hong Kong, Macao, Taiwan and mainland China), the Open Sky Agreements and long established colonial links, are key determinants of international air cargo flows from/to Taiwan. These results suggest a wider array of factors needs to be considered in policy.     

A passenger demand model for air transportation in a hub-and-spoke network

This paper develops an air passenger model that deals with city-pair demand generation and demand assignment in a single framework. Using publicly available and regularly collected panel data, the model captures both time series and cross-sectional variation of air travel demand. The empirical analysis finds that pattern of correlations among alternatives can be described by a three-level nested logit model. Fare, frequency, flight time, direct routing, on-time performance, income, and market distance have significantly effects on air demand. Correcting for the problem of endogenous air fares using instrumental variables yields more plausible estimates of price sensitivity and value of time.
