皖江城市带土地综合整治现状评价

通过分析阐明皖江城市带土地整治现状及存在问题,指导下一步土地整治工作的推进,进一步缓解土地供需矛盾,为皖江城市带的发展提供强有力的支持.采用查阅年鉴进行归纳总结,比较分析取得的成果和存在问题.各区域都有土地整治项目,但主要集中在江淮丘陵区;土地开发新增耕地比较大,但后备资源不足,加重了土地复垦和土地整理负担;整治后耕地质量差和权属不清;综合整理过程中缺乏环境影响评价;缺乏土地整治绩效评价和监管;忽视生态景观服务功能等.     

Causes of privatization in China

We test five hypotheses regarding the causes of privatization in China by using firm‐level panel data collected in 11 cities in the period 1995–2001. We have found that privatization is positively linked with hardened firm budgets and the extent of market liberalization, but is constrained by excessive debts and worker redundancy. Firm efficiency and state‐owned enterprises’ financial liabilities imposed on local governments are not factors of influence. These findings match the broad flow of events in China and highlight the role of market building in bringing about efficient institutional changes.     

基于模糊优选模型的输变电工程造价管理成效评价研究

输变电工程造价管理对于电网投资效益具有重要的意义.目前对输变电工程造价管理工作成效的评价往往依靠主观判断,缺乏一种客观、准确的评价方法,为此,本文针对输变电工程造价管理成效开展评价研究.首先运用德尔菲法、层次分析法分析输变电工程造价管理的影响因素,建立综合评价指标;其次,基于模糊优选模型建立造价管理成效评价模型;最后,...     

Total‐Factor Energy and Emission Efficiencies of ASEAN and Other Asian Economies

This research uses the slack‐based measure data envelopment analysis to compute the energy and emission efficiencies of Association of Southeast Asian Nations (ASEAN) and other Asian economies during the 2001–2017 period, employs the Malmquist productivity index to check for the main source of efficiency score changes due to technical changes, and then applies panel Tobit regressions to determine the factors explaining the efficiencies. Our empirical results show that the energy efficiency scores of ASEAN economies had been catching up to other Asian economies after the Global Financial Crisis, whereas the emission efficiency scores of various ASEAN economies had been falling behind other Asian economies over the same period. The main source of efficiency score changes over time is efficiency changes and not technical changes. Decreases in the fossil fuel ratio of net electricity generation and the secondary industry ratio within total industry improve both lead to improvements in energy and emission efficiencies.     

Investment in the absence of property rights; the role of incumbency advantages

In many situations the individuals who can generate some output must enter a contest for appropriating this output. This paper analyses the investment incentives of such agents and the role of incumbency advantages in the contest. Depending on the advantages, an increase in the productivity of the investment can decrease or increase the amount of investment. The results are applied to autocrats’ investment behavior and job specific investment in organizations.     

基于污染损失率的连云港水环境污染功能价值损失研究

水体污染是当前环境污染一个重要方面,有效评价水污染的价值损失是水环境规划、制定水环境对策与政策的基础。文章基于污染损失率法估算连云港水环境的功能价值损失,得出1996—2000年连云港的水环境污染功能价值损失年均高达11.8亿元,占GDP的比重年均为4.55%。表明连云港水环境污染损失较大,其经济发展在一定程度上是以水环境污染为代价的;目前以GDP为主要衡量指标的国民经济核算体系可能过高地估计了连云港的经济增长水平。     

演化经济学与新自由主义截然不同的经济政策观

“北京共识”的精髓是试验、创新和因时因地而制宜的经济政策,它与演化经济学的经济政策观之间存在着惊人的联系,但与“华盛顿共识”的新自由主义经济政策观截然对立。本文以“北京共识”的政策经验为背景,通过与新自由主义的比较,较为系统地总结了演化经济学经济政策观的六大原理历史重要与最小限度打乱原理;创造力原理;不确定性与意外原理;复杂与质量型的经济政策主张;系统政策观;试验与政策学习原理。这些原理对转型经济和发展中国家的经济政策制定具有重要的理论指导意义。     

生产者延伸责任的双重效应分析

《中华人民共和国固体废物污染环境防治法》的颁布从法律上确立了生产者延伸责任制度。资本逐利的本能驱使下，成本一收益成为几乎所有企业的共同思维定式，生产者延伸责任制度的确立压缩了生产企业的利润空间。但是，生产者延伸责任制度推行也给企业发展带来契机；推动生产企业持续的技术创新与生产流程再造，重新塑造为企业主动承担社会责任的新形象，同时也给企业带来新的利润增长点。     

云南省开展旅游电子商务的问题及对策研究

云南省旅游资源十分丰富，在信息技术飞速发展的今天，旅游与互联网的关系也日益紧密。通过发展旅游电子商务来加快云南省旅游资源的开发，带动全省经济发展就为了大家共同关注的话题。但云南开展旅游电子商务的现状却不客乐观，本文从介绍云南旅游电子商务现状入手，分析了云南开展旅游电子商务中存在的问题，提出了解决方案。     

Searching for the sunk cost fallacy

We seek to isolate in the laboratory factors that encourage and discourage the sunk cost fallacy. Subjects play a computer game in which they decide whether to keep digging for treasure on an island or to sink a cost (which will turn out to be either high or low) to move to another island. The research hypothesis is that subjects will stay longer on islands that were more costly to find. Eleven treatment variables are considered, e.g. alternative visual displays, whether the treasure value of an island is shown on arrival or discovered by trial and error, and alternative parameters for sunk costs. The data reveal a surprisingly small sunk cost effect that is generally insensitive to the proposed psychological drivers.
