燃气热水器步入万和时代？

近日,一个并不起眼的换届选举却引起了社会各界的广泛关注。记者从四川成都举行的“中国五金制品协会燃气用具分会第三届会员代表大会”中获悉,民营企业出身的广东万和集团成为新一届理事长单位,其集团总裁卢楚其先生被选举为第三届理事会理事长。万和如何带领中国热水器改天换地,颇令人关注。万和能带雁群突围?20年前,玉环、沈乐满、神州、万家乐四大家族瓜分天下;随后的神州、万家乐、万和三足鼎立的短暂过渡;上世纪90年代末,全国市场只剩下万家乐、万和两强争霸,燃气热水器行业似乎在演绎“双雄争霸”之路。万和最终的胜出使燃气热水器初…

中间选民理论在农民工市民化政策制定中的运用——基武汉市436位农民工的实证研究

The Median Voter Theory is an important theory in the neo-political economics. It can be applied to solve the collective choice paradox and analyze the policy making for the citizenization of peasant workers. Adopting the method of factor analysis, this paper makes an empirical study on peasant workers’ preference for citizenization. We find that there is a paradox of future residence preference and self-identification in peasant workers. On this basis, peasant workers are divided into 5 subgroups, and it is found that the median undecided peasant workers are the median voters. Based on the analysis of the median undecided peasant worker’s complaints and appeals, it is proposed that the country should strengthen the vocational training system, establish a social security system, expand the agricultural reform and promote educational reform to facilitate the citizenization of peasant workers. __________ Translated from Guanli Shijie 맜理世界 (Management World), 2007, (4): 40–67     

中国金融业分业经营与混业经营研究

实践表明，混业经营有助于增强金融机构的国际竞争力，促进一国经济的发展，目前已成为全球金融业发展的趋势。就我国而言，从长远的角度来看，混业经营是金融业的必然选择，但短期内尚不具备过渡的条件。由于我国已加入WTO，所以目前应抓住机遇，采取相应的对策，为将来混业经营作好准备。     

晶化时间对CoAPO-11分子筛合成过程中转晶的影响

本文研究了晶化时间对低钴含量(x=0.1)的CoAPO-11分子筛合成过程中转晶现象的影响,并采用XRD、SEM对产物进行表征。结果表明,200℃下晶化48 h,可获得纯相CoAPO-11;当晶化时间超过48 h时,产物便开始向[Co-Al-P-O]-GIS型分子筛转化;晶化延长至72 h时,产物已全部转化为[Co-Al-P-O]-GIS型分子筛,该转化过程不可逆。从分子筛骨架结构单元出发,阐述了转晶现象的内在影响因素。     

“以大代小”火力发电企业的价值评估

在火力发电行业进行“以大代小”技改工程后,为了解决“一厂多制”的问题,需要对完成“以大代小”技改项目后所产生的新发电企业进行价值评估。在评估过程中,应明确价值类型,充分考虑租赁的资产、委托运行维护管理等要素对企业价值的影响。本文对大型火电发电机组的生命周期进行了分析,并在此基础上提出了对“以大代小”新火力发电企业进行收益测算的“三阶段测算模型”。     

基于BP网络对我国通货膨胀率的预测及其分析

本文首先由我国的CPI计算出通货膨胀率,综合分析了我国通货膨胀率和GDP增长率数据。其次,用带有动量项和自适应学习率的BP神经网络预测出2008～2009年我国CPI,从而推算出2008～2009年我国通货膨胀率分别是4.99%和4.91%左右。并提出了一些相应的政策建议。     

关于产业集群技术创新的若干问题

Modelling the inflation process in transition economies: Empirical comparison of Poland, Hungary and Czech Republic

This paper starts from the observation that inflation in transition economies appears to be persistently high and volatile and attempts to provide some empirical characterisation of the inflation process in three such transition economies: Poland, Hungary and Czech Republic. We first consider the role of monetary growth as a major causal factor for inflation in these economies, and argue that the evidence provides rather weak support for the causal relationship. We then propose a transition economy cost-plus model and estimate this using the equilibrium-correction modelling (ECM) strategy augmented by introduction of a number of transitory factors and changes in the internal structure of the real economy which we believe may have had a significant impact on inflation in these economies. We show that this approach enables us to account for long-run inflation in these economies from the early 1980s to the present despite the turbulence of the latter part of the sample period. Our results support wage and exchange rate based inflation policies.
