Investigation on the Theory and Means of Construction Tendering and Bidding in the Period of Economy Transition

The tendering and bidding of engineering construction is a means, which makes use of the function of market mechanism to carry on or transmit the project.It has a history over one hundred years abroad, but it is used in China with great force only twenty years.Because actualizing construction tendering and bidding goes with the reform of market mechanism, the fashion of construction tendering and bidding in China is different from that customarily used internationally and there are many differences in means and procedures.In this paper, beginning with the theory of tendering and bidding, the premises of the first-price-sealed tendering and the current condition of China are compared and the means and development objects of tendering in the period of national economy transition are discussed.Finally, some problems and strategies to the problems of the mold of tendering of bill quantity of construction works are discussed.     

Should State and Local Government Bidding for Big Businesses Be More Like eBay?

During recent decades, and especially after the economic downturn that began in the late 2000s, many U.S. state and local governments have intensified their pro‐growth efforts to promote corporate investment and jobs, including ever higher incentives (such as tax breaks and grants) in their bidding wars for big businesses. This paper draws an analogy—between bidding for big businesses and bidding on eBay—to highlight the drawbacks of high‐profile bidding wars among governments given that the large corporations establish the bidding rules in their favor. The main consideration raised is whether state and local government bidding for big businesses, which operates analogously to an auction, should be more like eBay, whose rules are fair not only for sellers but also for bidders.     

土地违法对经济增长的影响研究分析

本文基于土地违法投入对经济增长的作用机理,通过实证研究分析了中国1999-2006年土地违法投入对经济增长的影响及贡献。研究结果：土地违法投入由于其获取方式和途径等不同对社会经济产生不同于合法土地投入的效应,因而产生了不同于合法土地投入对经济增长的贡献。从短期看,违法土地投入对经济增长的产出弹性远远小于合法土地投入,从长期看,违法土地投入不利于土地的合理投入和集约利用,对经济增长并不能产生正的贡献。因此,政府应该从多方面措施入手,最大程度地遏制土地违法现象的发生。     

全球金融危机中的我国金融业及农业风险分析*

摘要：产业结构的变动是国民经济发展的重要特征,投入产出模型是检验经济中各产业的相互联系,进而分析一个国家或地区的宏观经济运行情况的一种经济数量分析方法。面对全球金融危机,本文运用投入产出表对金融产业与其他产业结构进行关联分析是深刻揭示金融产业结构内在机理的重要方法。本文选用了中间投入率、影响力系数、感应力系数三个指标来分析在全球金融危机中,北京、上海金融业的发展问题。研究发现,金融危机对于中国经济产业的直接冲击不会太大,但是对北京、上海的冲击可能是相对严重的。当前需要注意截断房地产开发业金融业的强烈作用,同时维护农业的发展。关键词：金融危机,投入产出;中间投入率,中国;北京;上海

Rural–urban transition in China: illegal land use and construction

This paper takes issue with the desakota model developed by Terry McGee by elucidating the illegal land use and construction in the rural–urban transition zone in China, with the additional case study of Tianhe Village in Guangzhou City. The paper emphasises the need to examine the geography of illegal activities along the approach of geographies of difference. It has shown that illegal land use and construction is prevalent in rural China. In rural areas where cultivated land has been converted to non‐agricultural purposes, peasants are left with no alternative but to use land and construct buildings illegally. Some have increased their income by leasing out flats to migrant workers, whereas others have not been able to do this. This study has revealed that underneath the positive and integrative picture portrayed by the desakota model is its negative and disintegrative counterpart. Illegal land use and construction is one such example. Unless we incorporate both into our studies, we will not be able to comprehend the urban morphology of Chinese city regions in the new millennium.     

Short-and Long-Term Effects of the Construction Industry on the Economy Growth

The construction industry could be developed as a pillar industry of the national economy,since it has a strong pulling role in economic growth.However,little definite empirical evidence supports this argument.Using co-integration and Granger causality tests and error-correction model with taking Sichuan for an example,this article studies both short-term and long-term effects of the construction industry on the economy growth.Empirical tests show that in the long term the economy maintained equilibrium relations with the construction industry.A growth in the construction industry will lead to the economic growth;however the pulling role of the construction industry on the economy is limited.A growth in the construction industry will not predict economic growth in the short run.Thus,for Sichuan case the government is unable to stimulate the economy by focusing on development of the construction industry in the short run.Instead,in order to promote long-term development of the national economy it could implement stable and healthy development policies for the construction industry.

广西木薯产业化发展对策

木薯是广西一种重要的经济作物,其用途很广,经济价值较高,特别是中国加入WTO后,蔗糖业生产遭受巨大冲击的情况下,木薯生产将成为广西重要的支柱产业,成为广西经济发展的新的增长点。广西气候、土壤适于木薯生长,木薯生产具有明显的自然优势,木薯耐旱耐瘠,生产成本相对较低,广西木薯年种植面积23~28万hm2,占全国木薯种植总面积的60%,然而,广西木薯产业化发展也有一些问题有待解决,主要是加工业发展滞后,木薯品种单一、老化,生产布局不甚合理、栽培管理粗放等;因此,广西木薯产业化发展必须大力发展木薯加工业,特别是深加工业,提高木薯生产的经济效益,选育、推广高产高粉木薯良种,改进木薯栽培技术,建立健全木薯种植、加工标准化技术体系,科学处理木薯加工“三废”,解决环境污染问题。

Measurements to Protect Owners'' Benefits under the Non-price Bottom Bidding

Investment on construction projects has become an important factor in improving the development of economy in China.The non-price bottom bidding is a representation that the investment on projects is becoming standardized.During the years of trying out the non-price bottom bidding,the colluding in bidding or bidding below the cost has happened several times,which have damaged the benefits of owners.To solve theses problems,this paper firstly studies the reason of these problems-the failure in the normal relationship between principal and agent.Then,some measures have been presented as follows: building systematic and scientific system of qualification prejudication,judging behaviors of colluding in bidding and bidding below the cost with reason and providing a surety mechanism of the project.The authors hope that these measures are beneficial to non-price bottom bidding.     

Something New or More of the Same in the Bidding Wars for Big Business?

The economic downturn that began in 2007–2008 was blamed by some commentators on neoliberalism and pro‐business policies. So we might expect U.S. state and local governments to have responded with policy changes affecting their neoliberal economic development strategies. Based on this assumption, this paper is a theoretically informed examination of recent high‐profile bidding wars in Wisconsin. The highest profile example was in 2009 when General Motors chose a plant in Michigan over Wisconsin and Tennessee for a new small car line. Wisconsin's Commerce Secretary characterized Michigan's $1.2 billion incentive offer as “absolutely crazy” (compared with his state's $409 million offer!). My main research question is how have Wisconsin state and local governments adjusted their neoliberal economic development efforts in these bidding wars given the recent economic downturn and weak economy? This paper uses the largest incentive offers in Wisconsin during the tenure of the current and previous state governors within the context of ten themes drawn from the literature to problematize the neoliberal policy of bidding for big business. It concludes by considering the implications for economic development policies.     

鱼类食性的基因调控与遗传改良研究进展

食性是影响鱼类生长的重要性状,也是鱼类遗传改良研究中的一个重要内容;食性受多种因素调控,不仅与内在的遗传和生理因素如食欲、消化道结构有关,还与外在的饵料性质如蛋白来源、饲料适口性等有关;其中,相关基因的遗传调控是食性的主要决定因素。通过改良鱼类的食性,促使依赖冰鲜投喂或依赖活鱼饵料的养殖品种接受人工饲料,可扩大鱼类尤其是肉食性鱼类养殖产业的规模,提高养殖产业的经济效益。本文从鱼类食性的基因调控和改良研究方面进行综述,结合食性相关基因的多态性和人工饲料蛋白源等方面研究,以期为进行鱼类食性的遗传改良的研究提供帮助。
