资源型城市转型与循环经济发展--以黑龙江省伊春市为例

随着人类对资源的不断利用,资源型城市大都面临着转型问题,如何实现资源型城市的可持续发展,既是一个需要研究的理论问题,更是一个亟待解决的实际问题。通过伊春市经济资本和技术资本发展困境分析,采用生态足迹方法计算了资源型城市伊春市2003年的生态足迹,得出此地区尚未出现生态赤字,但对它的转型却迫在眉睫,据此提出了伊春市应向循环经济型生态城市转型的思路及实现路径和方法。     

政治关联、金融发展与债务治理——以我国国有控股上市公司为例

债务融资要发挥治理功能,需要硬的约束环境。然而,政治关联的存在会破坏这种硬约束环境。但金融发展水平可以降低政治关联的这种不利影响,从而促进债务治理作用的发挥。基于这一推理,以我国沪深两市A股上市公司2006～2010的全面板数据为样本,研究了政治关联、金融发展对债务治理功能的影响程度及方向。研究结果表明:政治关联会削弱长期债务的治理功能,其对短期债务的治理功能没有产生负面影响;金融发展水平的提高一方面可以进一步提升债务的治理功能,另一方面可以减弱政治关联带来的不利影响。     

民营经济发展战略研究

当前,国内民营经济发展主要有三种模式,即温州模式、苏南模式和青浦模式.三种模式对发展我国民营经济都具有借鉴意义,但不能照搬照抄.民营经济发展战略是一项复杂的系统工程,民营经济发展可采取集团化战略、多元化战略、融资战略、人力资源开发战略等四种战略,这四种战略都具有现实意义.     

Do city–county mergers in China promote local economic development?

Municipal mergers have become a worldwide phenomenon in the past few decades, primarily advanced to exploit economies of scale. While most evaluations of municipal mergers have focused on the efficiency of local public goods provision, it is rare in the literature to explore how such mergers promote economic growth in a developing country context. This research investigates the economic consequences of a policy experiment of city–county mergers (che xian she qu) in China during the period 2000–2004. Using comprehensive datasets at city, county and firm levels, we present evidence that the merger significantly increases local economic development, and the magnitude of the effect depends on local endowments related to agglomeration forces. The results are robust to a number of different model specifications. We further verify that improved transport infrastructure and urban agglomeration economies after merger are potential contributors to the positive merger effects.     

经济发展与生态保护的思考——橡胶种植与热带雨林

文章在分析经济发展和生态保护的内涵和辩证关系的基础上,通过探讨云南省西双版纳傣族自治州在社会经济发展过程中存在的生态环境矛盾,指出兼顾生态保护的区域经济发展模式才是可持续发展之路,并从宏观上就经济发展中的生态保护问题提出了有益的建议.     

世博会与城市发展的互动演化关系及其当代价值

研究表明,世博会与城市发展之间的互动演化关系贯穿了整个世博会的举办历史。世博会作为交流、展示和传播城市文化科技成果的平台,关注的焦点总是追随着城市创新的演化轨迹。当代城市创新以技术与文化艺术的渗透融合为主要特征,为满足价值活动的创新需求,世博会也在积极酝酿新一轮的功能转变。反过来,世博会的功能演化同样深刻影响着城市发展的方向。特别是当全球竞争重心向城市和区域转移时,世博会的地方化色彩逐渐浓厚,并被视为区域开发和城市增长的战略工具。然而,由于城市追逐资本的传统竞争模式因其不可持续性而饱受诟病,从而要求人们在全新的背景下重新审视当代世博会对于城市转型的价值意义。现身说法地践行世博会主题倡导的内容,积极探索功能转变的新方向,是时代赋予2010年上海世博会的责任与使命。上海应以此为契机,通过提高地域竞争优势、探索区域合作的制度创新、发展文化创意经济和现代会展业,尽快融入全球城市网络体系。     

Does different NPD project’s characteristics lead to the establishment of different NPD networks? A knowledge perspective

In today’s highly competitive and globalised marketplace, firms need more and more to develop new knowledge and capabilities to leave behind their competitors, thus gaining market share. Knowledge is fundamental for success because a firm that knows more, often develops more sustainable competitive advantage. Networks, like those oriented to New Product Development, seem to be valuable means of learning, as firms could not achieve alone the same results, or at least not as quickly. Through this integrative systematic review, we are interested in understanding whether different New Product Development projects correspond to different New Product Development networks in terms of knowledge exchanged among the partners involved. Our results highlight the presence of four types of New Product Development networks deriving from the combination of the degree of innovation characterising the project and its mode of development. Implications and future research are also proposed.     

Factors in the Development of Trade Credit: Case Study of Provinces in China

Using Chinese province-level panel data for 2001-9, we investigate significant factors for the development of financial intermediation via trade credit in developing economies. First, we confirm that a competitive market environment, a well-functioning legal system, and greater bank loans for non-state-sector firms promote the development of trade credit in China. Conversely, corruption hinders its development. Second, we find that proper functioning of the legal system and bank lending to non-state-sector firms are highly likely to be the causes of the complex relationships between these determinants. Finally, we observe that an increase in the number of lawyers effectively improves the quality and function of the legal system, which, in turn, alleviates the harmful influence of corruption on trade credit development.     

分子影像学在药物研发领域的应用进展

越来越多的证据表明,分子影像技术可以帮助解决在药物开发过程中出现的关键问题。例如计算机断层扫描、磁共振成像技术和正电子放射断层造影术可以实现对生物活性灵敏高效的检测,对药代动力学和药物剂量的确定提供佐证,另外对药品的注册申请提供数据支持。本文中将介绍关于分子影像技术应用于药物研发的发展动态。
