淮河流域污染治理需要企业实施绿色营销

作为我国重要的农产区和传统工业生产基地,淮河流域污染严重,治理污染刻不容缓。由于淮河最主要的污染源来自工业企业,本文着重从工业企业这一微观角度出发,引入绿色营销的概念,分析了企业加强环保意识的重要性,并通过对企业实施绿色营销的博弈分析,指出绿色营销是企业保证可持续发展的必然选择。

专业技术人员职业倾向与职业成功关系实证研究

在目前专业技术人员流失率居高不下的背景下,管理专业技术人员职业倾向对有效发挥专业技术人员作用具有重要意义。本文围绕专业技术人员职业倾向与职业成功关系展开实证研究,发现专业技术人员呈现多样化的职业倾向,并不是以技能型及其相关的职业倾向为主导;同时发现专业技术人员的一些个人因素会影响其职业倾向和职业成功,不同的职业倾向会影响职业成功的不同方面。论文依据专业技术人员职业倾向特点及其对职业成功的不同影响,提出了保留和激励专业技术人员的建议。     

Explaining momentum profits with an epidemic diffusion model

We show that information diffusion is a function of its dissemination and assimilation. Whereas dissemniation is a function of observable factors such as volume and price volatility, assimilation is dependent on unobservable factors such as the usefulness and reliability of information. We find that buying low volume (or low volatility) past losers and shortselling low volume (or low volatility) past winners generates a positive net return across the entire sample period and especially during bear markets. Second, buying high volatility past winners and shortselling high volatility past losers generates a positive net return, especially during bear markets.     

谈我国信用标准的方案设计

信用标准为征信机构的设施建设、技术和操作提供了规范,对征信产品质量提出了明确的要求,必将对我国征信行业的发展产生重要影响。借鉴国际经验,加快信用标准化工作并把握好标准的设计是当前的一项重要任务。     

振兴东北老工业基地与内蒙经济发展区域协作的基本思路

东北三省和内蒙古东部组成的东北经济区,是我国最早形成并在结构上相对完整的大经济区,有着区域经济协作的天然条件和深厚基础。在振兴东北老工业基地的战略规划和实施中,要以区域经济一体化思想为指导,站在地区分工与协作的高度,分析和研究振兴东北老工业基地与内蒙古经济发展的相互关系,区域协作的阻滞性因素、协作的主体领域以及推进三省一区区域经济协作的总体措施,以实现要素区域间优化配置,从而加快振兴东北老工业基地的进程,使东北大经济区成为我国第四经济增长极。     

Microeconometric models of infrequently purchased goods: An application to household pork consumption

The double-hurdle and infrequency-of-purchase models are generalized with the inverse hyperbolic sine transformation in the dependent variable. The resulting specifications feature more flexible parameterization and error distributions than the untransformed models. Using the 1987–88 Nationwide Food Consumption Survey data on household pork consumption, a nonnested test suggests that the IHS double-hurdle model provides better characterization of the data-generating process than the IHS infrequency-of-purchase model but the elasticities derived from these models are similar. Own-price effects on the probability and level of consumption are negative and significant, but the elasticities are small. Income and cross-price effects are not significant. Household age composition, education, gender of meal planner, and race are among the demographic variables that affect consumption.     

FDI对东道国就业的直接效应和间接效应--基于柯布-道格拉斯生产函数的分析

在FDI发展历史的早期,就有学者关注FDI对东道国就业的直接效应和间接效应问题。1994年和1999年的《世界投资报告》从不同的角度对这一问题进行了较全面的概括和总结。本文在此理论基础上,利用柯布-道格拉斯生产函数,分析了FDI对东道国就业的直接效应、短期间接效应和长期间接效应,并给出了FDI对东道国就业的影响因素,以及各因素之间的关系。得出的结论可以为政府在不同阶段制定相关政策提供相应的理论依据。     

Linking Public Investment to Private Investment. The Case of Spanish Regions

Public investment constitutes one of the main instruments of regional policies. The existence of a direct link between infrastructure and regional income per capita is usually accepted. Literature also describes a positive effect of public investment on private capital accumulation. This paper seeks to provide new empirical evidence on this latter relationship for the case of Spanish regions over the period 1965–1997 using panel data methodology. The results show a positive effect of productive and social public investment (especially in education) on private investment. The spillover effects generated by the productive infrastructures located in other regions do not seem to encourage the private investment in neighbouring regions. Public consumption and interest rate exert a negative influence on private capital accumulation. These results are robust to changes in the econometric specification.
