转型期国有企业改革的伦理困惑与破解--基于中国的实践和西方的经验

经济转型意味着旧的"社会契约"被打破,而新的契约尚未订立,作为企业行为调控机制的伦理作用得以彰显.我们在分析市场经济体制下,西方企业在不同管理时代的"伦理"与"绩效"关系的基础上,阐明企业伦理本身的特有属性及经营绩效的内涵;同时结合中国国有企业目前面临的伦理困惑,认为国有企业要破解这些伦理困惑,就必须根据变化了的现实对其管理伦理进行合理定位,以"社会期望"为前提谋求企业与社会的和谐,以市场经济游戏规则为准谋求企业之间的和谐,以人本管理为依托达到企业与员工关系的和谐统一、以生态优先为基准谋求企业与自然的伙伴关系,以与全球经济接轨为基础实现国有企业组织个性化,以"权威声誉、伦理声誉"营造社会激励伦理行为的氛围.     

World Oil Depletion Models: Price effects compared with strategic or technological interventions

World oil depletion, including natural gas liquids, was modelled in the past by many authors. Recently, Guseo and Dalla Valle have introduced and Guidolin has applied a new approach following perturbed life-cycle diffusion models. Here we examine joint effects of economic and strategic or technological interventions using a Generalized Bass Model (GBM). Statistical analysis takes into account three different hierarchical levels: natural diffusion, long memory interventions and stochastic components. The main results confirm the statistical significance of historical 1970s shocks and highlight a strong long memory effect due to an increase in oil production after World War II. The estimated peak-date, 2007, and the 90% depletion time, 2019, are determined under an equilibrium intervention hypothesis.     

我国旅游价格管理：现状、改革背景与政策分析

旅游业发展是一项复杂的系统工程，需要各相关行业和各项政策措施的配套协调。由于旅游价格的杠杆效应，如何应对入世给我国旅游业带来的挑战，改革并完善与国际接轨的旅游价格管理新体制是每一个旅游价格管理工作者应当思考的现实问题。     

吐鲁番葡萄沟景区旅游形象定位及塑造研究

本文首先分析了旅游形象对于一个旅游目的地的重要性以及吐鲁番葡萄沟景区建立旅游形象的紧迫性。然后结合吐鲁番葡萄沟景区的实际,分析其旅游资源的现状及特色,运用调查问卷的形式对吐鲁番葡萄沟景区的旅游形象进行受众调查,并对其旅游形象替代性进行分析,然后定位吐鲁番葡萄沟景区的旅游主题形象,最后从理念形象(MI)、视觉形象(VI)、行为形象(BI)、旅游形象传播四个方面对其旅游形象进行塑造。     

会计信息质量与市场定价分析

本文以应计质量、盈余持续性、盈余可预测性、盈余平滑度作为会计信息质量的代理变量,通过研究会计信息不同纬度的质量与权益资本成本之间的关系,为投资者的市场定价及对信息质量的关注程度提供证据。研究结果表明,除盈余的持续性不显著外,其他各项质量与权益资本成本之间均呈负相关关系;在对权益资本成本的影响程度方面,无论是单独影响还是条件影响,应计质量影响程度最大,其次是可预测性。     

对企业技术创新自我实现的经济学分析

本文从经济学的理论角度分析了企业技术创新自我实现的可能性。分析发现：产品被成熟生产后的产量与资本报酬和资本边际生产率的大小有直接关系。因此，企业发展内部本身就可以通过市场供需调节来实现创新的循环和延续。从这一点上说，国家对于企业技术创新的鼓励政策应该更加依靠市场机制的作用。     

Theory Analysis of Model for Price Fluctuations in a Single Commodity Market

The price model for a single commodity market is a very important economic model that describes the basic rules for price fluctuations in a single commodity market. In this paper, we investigated the general case for the model, and proved that every positive solution is bounded and we obtained a necessary and sufficient condition for oscillation of every positive solution concerning positive state solution.     

The price relationship between organic and non-organic vegetables in the U.S.: evidence from Nielsen scanner data

This study investigates price relationships between organic and conventional carrots, tomatoes, and lettuce in the U.S. utilizing Nielsen scanner data from 2006–2015. We employ a threshold vector error correction model (TVECM), threshold vector autoregressive model (TVAR), and threshold cointegration test to test whether market integration exists between organic and conventional vegetables as well as the existence of asymmetric price transmission. The results find positive long-run relationships between organic and conventional prices of carrots and tomatoes and show the existence of asymmetric price transmission in price pairs of lettuce and tomatoes. Our findings suggest that the price relationship between organic and conventional vegetables varies by characteristics, such as shelf life, volatility in the price premium, and substitutability.     

由临街地价推算区片价的方法探讨

如何利用临街样点地价推算区片平均地价及基准地价始终是城镇基准地价评估的一个难点。文章利用赤峰市的实际调查数据,分别采用临街贡献率和面积加权两种方法推算区片平均地价,并采用回归分析方法探讨区片价与临街地价之间的关系,结果证明两种方法所推算的区片平均价是基本一致的,而且区片价与临街地价之间呈“反S”曲线关系。     

Strategic Firm Behavior Under Average-Revenue-Lagged Regulation

Price caps have been shown to have incentive properties superior to traditional rate of return regulation. Average-revenue-lagged regulation (ARL) is attractive in that steady-state prices are known to be efficient. We show that the ARL scheme can be manipulated by the firm so as to yield the unregulated global profit maximum. While tests exist that can provide the regulator with evidence of this strategic behavior, we also demonstrate that the unregulated global profit maximum will not be attainable if Laspeyres (L) regulation is employed.Jel classification: L43, L51I would like to thank Michael Crew and an anonymous referee for their extremely helpful suggestions.
