基于面板数据模型的我国农村商业银行可持续发展能力分析

本文通过构造面板数据模型分析了我国各区域农村商业银行的可持续发展能力,结果发现,农村商业银行的利润主要来源于利差,时间因素的变化对农村商业银行发展也存在不同影响,东部地区农村商业银行的可持续发展能力明显强于中西部地区,从供给角度看,这与当地政府的政策扶持及各机构的创新能力等有较大关系。     

Cointegration Analysis of Audit Pricing Model: A Panel Unit Root Test Approach

In this study, we provide evidence on the stationarity of real audit fees and the major explanatory variables frequently used in the audit pricing models from a pooled data set, using panel unit root tests developed by Im et al. (1997). The panel unit root test supports the hypothesis of non‐stationarity of audit fees and their major determinants. We demonstrate that variables in the audit pricing model that were previously found to have impact on audit fees may turn out to be useless when more powerful tests like panel tests are applied to these variables. Our evidence implies that failing to employ appropriate procedure to test cointegration and to specify the appropriate model for audit fees and their determinants would generate results that may have exaggerated the effects of some variables on audit fees.     

财政收支视角下的江西公共服务--基于EG两步法和误差修正模型分析

财政收支的长期均衡关系影响到公民享受公共服务的福利。通过运用EG两步法检验江西省1978-2012年间财政收支之间是否存在长期均衡关系,结合误差修正模型分析江西省财政收支的短期和长期关系。实证结果表明：江西省财政收支存在长期均衡关系,当短期波动偏离长期均衡时,误差修正项以0.337007的力度进行反向调整,使得非均衡状态向均衡状态回复。进行格兰杰因果关系检验,发现江西财政支出是财政收入的格兰杰因果关系,说明作用于公共服务上的财政支出能够带动国民经济的增长,在一定程度上带来财政收入的增加。
