我国地方政府绩效管理的行政生态学分析

我国地方政府开展的政府绩效管理实践存在着理论范式的形式完美主义、评估体系的＂官本主义＂、实践过程的简单主义的问题。运用行政生态学理论来分析,可以发现我国政府绩效管理处于独特的内外生态系统中,只有深入认识和揭示内外生态系统内涵及其关系,才能有效推动地方政府绩效管理改革。     

An empirical evaluation of China’s monetary policies

This paper investigates the responsiveness of the Chinese government’s monetary policies in terms of the money supply and interest rates to economic conditions and the effectiveness of these policies in achieving the goals of stimulating economic growth and controlling inflation. We analyze the responsiveness and effectiveness by estimating the Taylor rule, the McCallum rule, and a vector autoregressive model using quarterly data in the period of 1992-2009. The results show that, overall, the monetary policy variables respond to economic growth and the inflation rate, but the magnitudes of the responses are much weaker than those observed in market economies. Money supply responded actively to both the inflation rate and the real output and had certain effects on the future inflation rates and real output. The official interest rates, on the other hand, responded passively to the inflation rate and did not respond to the real output. They do not have any effect on future inflation rates and real output either.     

Nonparametric panel estimation of online auction price processes

In this study, we examine the price process of eBay online auctions. We pool sparse and unevenly spaced bidding histories of individual auctions, resulting in an unbalanced panel of bids. Since the price processes of online auctions are monotonically increasing within individual auctions and exhibit a substantial degree of heterogeneity, we propose a monotone series estimator for panel data with auction-specific slopes for a common relative price growth curve. We generalize Ramsay’s (1998, J R Stat Soc B 60(2):365–375) monotone series estimator to fit our panel model of the price process. We apply the proposed model and estimator to eBay auctions of a popular hand-held device (a Palm PDA). The results are shown to capture closely the overall pattern of observed price dynamics. In particular, the early bidding, mid-auction bidding drought, and end-auction bid sniping are well approximated by the estimated price curve.

日本货物贸易模式背离倾向演进研究:1976～2011

日本经济在进入稳定增长阶段后走上了一条出口导向型的经济发展道路。利用1976～2011年的SITC三位数分类产品的贸易数据,本研究根据产品的技术结构将其重新聚合为10大类别,进而深入分析了日本在各个产品类别上"净出口比率"、"对称的显示性比较优势指数"以及"贸易模式背离倾向指数"的静态分布和动态演进特征。在样本期间内,日本的货物进出口贸易普遍存在着净出口相对能力超出比较优势实际水平的贸易模式"正背离倾向"。在1985年"广场协议"和1986年"前川报告"后,日本的贸易模式开始明显地向均衡方向回复,但直至2011年,日本在绝大多数产品类别的贸易模式上仍然存在"正背离倾向"。本研究认为,对出口导向型经济发展方式的调整难以一蹴而就,并且是一个长期而痛苦的转型过程。     

Organisational justice and customer citizenship behaviour of retail industries

Previous research has concerned itself more with customers' purchasing behaviours but not non-purchasing behaviour. Hence, the purpose of this study is to investigate the organisational justice (OJ) and customer citizenship behaviour (CCB), including the mediating role of organisational trust. A survey was conducted on a sample of 447 fast-food restaurant customers in Taiwan in order to test the proposed model. The findings showed that the customers who have higher perceptions of justice have higher levels of trust and CCB. Positive relationship was found between trust and CCB. In addition, trust has a partially significant mediating effect between OJ and CCB. The findings are discussed in terms of their theoretical and practical implications, and also provide some suggestions for managerial practice and further research.     

多媒体在工科院校教学应用中存在的问题及改进

多媒体已经成为高校教学不可缺少的手段之一,与传统教学相比有很大的优势,但在工科院校的应用中存在着教学节奏快、应用不恰当等缺点。根据上述特点,多媒体在教学实践应用中应注意与传统教学的适当结合、人机互动性的调动和实践知识的引入。     

“用负债比例显示企业质量”模型述评

“用负债比例显示企业质量”是信息经济学在企业资本结构理论方面的一个应用模型，它从信息不对称的角度指出资本结构是有关的，是资本结构理论最重要的模型之一。然而，一方面，这个模型存在企图用一个已知信息求解两个未知信息的严重缺陷，另一方面，它仍然局限于完全信息的理论框架内，值得进一步深化。
