Anthony B. L. Cheung 《Public Organization Review》2006,6(3):221-236
This article examines the degree of autonomy of Hong Kong’s Airport Authority (AA). Traditionally, airport management in Hong Kong was the responsibility of the government’s Civil Aviation Department. The AA was established in 1995 to manage the new international airport at Chek Lap Kok which opened in 1998. It was expected to run as a commercial enterprise but, because of its strategic importance, there was concern that it should not become an independent empire detached from government control. As a hybrid type of organization, the AA has moved steadily towards full commercialization. The government has also put its privatization on the agenda. Its transformation may have some implications for the redefinition of the future autonomy boundaries of public corporations in Hong Kong.

股价信息含量与资本投资效率——基于投资现金流敏感度的视角 总被引:2,自引:1,他引:2
本文以2001-2008年在沪深证券交易所上市的制造业公司为研究样本,基于投资现金流敏感度的视角研究了股价信息含量与资本投资效率之间的关系,得到以下研究结论 :富含信息的股价有效降低了资本投资对现金流的敏感程度。进一步研究后发现,富含信息的股价不仅能够有效降低融资约束导致的投资现金流敏感度,而且也能够有效降低代理冲突导致的投资现金流敏感度问题,以上结论在添加了诸多影响资本投资的控制变量及稳健性检验后仍然成立。本文的研究从一个全新的视角证明,富含信息的股价通过缓和融资约束和代理冲突问题,有效地改善了企业的资本投资效率。 相似文献

地区收入、食品价格与恩格尔系数 总被引:2,自引:0,他引:2
本文以2016年我国31个省级地区截面数据为样本,构建扩展模型考察恩格尔系数与收入、食品价格之间的关系。研究发现,恩格尔系数与地区收入存在显著的负相关性,纳入食品价格后收入对恩格尔系数的影响变得更为显著,二者关系满足恩格尔定律。恩格尔系数和以地区食品价格平价代表的食品价格之间显著正相关,若再考虑其他因素,则食品价格对恩格尔系数的影响会稍有减弱。进一步将食品区分为生活必需型食品与非生活必需型食品,测算得到的基本恩格尔系数、高阶恩格尔系数与收入之间仍呈负相关关系,但与基本恩格尔系数相比,高阶恩格尔系数与收入之间的负相关性更弱。恩格尔系数受生活必需型食品价格的影响强于非生活必需型食品价格的影响,基本恩格尔系数主要受生活必需型食品价格的影响,而高阶恩格尔系数同时受到两类食品价格的影响。 相似文献

This paper investigates the nature of optimal prices for a durable good in the presence of continuous quality improvements. The analysis of optimal prices is based on a nonlinear dynamic model of sales response that relates price, quality, average life of a product and the persistence of quality perceptions. Numerical solutions to the model are derived by employing the generalized reduced gradient algorithm. The results show that optimal price depends on the persistence of quality perceptions and the average life of a product (an aspect of quality). The analysis of optimal results affirms results based on other models and provides insights on the influence that quality has on optimal pricing. The implications of the results and suggestions for future research are discussed. 相似文献

Li Zhao 《The Career development quarterly》2012,60(4):355-366
Drawing from social cognitive career theory ( Lent, Brown, & Hackett, 1994 ), this study explored social supports’ influence on the career choice consideration of farmers during China's current process of urbanization. A questionnaire was designed based on interviews with 140 people and a pretest with a sample of 419 participants. A total of 628 participants were involved in the formal questionnaire survey. Results indicated that social supports had a dual effect: Positive supports were indirectly related to career choice consideration through the mediation of career self‐efficacy, whereas negative supports were related to career choice consideration directly. Implications for future research and the development of a career guidance and social support system for Chinese farmers are discussed. 相似文献

对城镇老年人退而不休的动因分析,是合理开发和管理老年人力资源的前提.基于代际支持的传导作用,研究发现,具有较高社会保障水平、健康状况较好和学历较高的城镇老年人选择退而不休更倾向于实现自我价值,同时,足够的家庭养老支持对他们积极发挥余热的动机有正向推动作用;而健康状况较差和学历较低的城镇老年人,由于家庭养老支持不足、其付出与获得的家庭资源不对等以及由此产生的社会保障"外溢"等压力,更可能以获得收入为动机选择退而不休,进而导致其发展权利受损.因此,有差别地开发和管理老年人力资源、谨慎制定并实施延迟退休政策,对实现积极、健康的老龄化社会有着重要的意义. 相似文献

In this article, two new powerful tests for cointegration are proposed. The general idea is based on an intuitively appealing extension of the traditional, rather restrictive cointegration concept. In this article, we allow for a nonlinear, but most importantly a different, asymmetric convergence process to account for negative and positive changes in our cointegration approach. Using Monte Carlo simulations we verify, that the estimated size of the first test depends on the unknown value of a signal-to-noise ratio q. However, our second test—which is based on the original ideas of Kanioura and Turner—is more successful and robust in the sense that it works in all of the different evaluated situations. Furthermore it is shown to be more powerful than the traditional residual based Enders and Siklos method. The new optimal test is also applied in an empirical example in order to test for potential nonlinear asymmetric price transmission effects on the Swedish power market. We find that there is a higher propensity for power retailers to rapidly and systematically increase their retail electricity prices subsequent to increases in Nordpool's wholesale prices, than there is for them to reduce their prices subsequent to a drop in wholesale spot prices. 相似文献

政府支持界限和角色定位对农村合作组织发展产生重要的影响。目前我国地方政府对农村合作组织的支持存在支配型、引导型、不支持型等三种类型,这三种支持界限的类型都导致了我国农村合作组织的发展呈现出诸多的问题。我国地方政府在农村合作组织发展的中应“进退”并举:政府应逐步从农村合作组织的内部管理中退出;在政策性领域政府的行动力度和范围要继续扩大;建立统一、规范、竞争、有序的市场体系。 相似文献
