中国参与全球价值链的特征与启示

研究目标：揭示2000年以来中国参与全球价值链（GVC）的程度、位置、竞争力特征,以及与主要经济体在GVC中的双边联系特征。研究方法：采用新近发展的生产分解模型,从前向联系和后向联系两个视角全面分析。研究发现：中国在GVC中的国际竞争力主要体现在制造业部门,已经具备“制造强国”的基本特征,接近GVC的中上游位置。大多数国家都对中国市场形成了高度的依赖性,同时中国成长为全球中间品的最大供应国,在GVC中扮演着关键的“枢纽”角色。研究创新：在一个统一的核算框架下,本文从多重视角首次对中国参与GVC的特征做出系统性的论述。研究价值：本文对于决策部门评价中国参与GVC的成效,研判国际经济关系,制定对外经济政策具有重要参考价值。     

To what extent do earnings affect the R&D decision of Chinese manufacturing firms?

ABSTRACT

As R&D activities are involved in inherent uncertainty of large investment, high risk and long return periods, earnings, as the main source of internal financing, have been a significant factor of R&D decision in the firms. In contrast to the previous research, this study investigates the impacts of firm’s earnings on R&D decision, in which earnings are measured by the indicators of earnings level, earnings quality and earnings persistence, while separating firm R&D activity into two stages of (i) the decision to undertake R&D activity and (ii) the amount to be invested on innovation activities. We document that earnings level can increase the probability of undertaking R&D activity, but has no effect on R&D investment intensity. Earnings quality and earnings persistence have a promotional effect on both stages of R&D decision. The empirical evidence of the subsamples shows that the impacts of earnings are heterogeneous across different ownership and technology-intensity firms.

区域异质性视域下京津冀产业升级的就业效应研究

基于京津冀一体化的背景,从异质性视角实证分析京津冀1990～2012年产业升级对第三产业就业波动的影响.从产业结构变动和产业技术变化两方面衡量产业升级,不仅关注产业结构变化,更关注劳动节约型的技术进步导致的“就业挤出”效应和资本节约型技术进步形成的“就业促进”效应,有助于政府解决产业升级和就业促进两大难题.研究发现产业升级与就业波动之间存在显著关系,产业结构升级和产业技术进步能提升就业规模,但产业技术进步速度和产业结构调整速度抑制就业增长速度;京津冀分组研究表明,三地产业升级对就业波动的影响差异性大.     

政府投资项目和谐管理体系及应用

科学发展观视角下西部资源型城市科学转型研究——以甘肃省为例

伴随着主体资源的枯竭,曾为国家和地区经济发展以及城市化进程做出了重要贡献的资源型城市,将不得不面临转型的现实选择。资源型城市的转型是一项系统工程,不仅是指资源型企业的转型,更是涉及到经济、社会、生态、文化等多种耦合因素的转型。文章以西部地区典型的资源型省份甘肃省为例,从资源型产业周期特点出发,结合甘肃资源型城市转型中所面临的现实问题,提出了在科学发展观指导下甘肃资源型城市科学转型的思路,并在这一思路的基础上提出了促进甘肃资源型城市转型的对策建议,以期对西部其他省份资源型城市转型提供借鉴。     

促进我国高新技术产业发展的税收政策建议

税收政策对高新技术产业发展具有明显的作用，但我国的税收政策存在着影响高新技术产业发展的问题，应通过颁布特别法案；规范科技税收政策；率先实行增值税转型；完善现行所得税优惠政策；加大鼓励企业科技研究与开发投入的税收优惠政策力度；建立鼓励风险投资税收优惠政策体系；建立符合WTO要求的技术创新和高新技术的税收优惠体系等措施加快高新技术产业的发展。     

System analysis and path choice for modem agricultural development： a case study of Suzhou

From the view of system theory, modern agriculture in a region embodies elements conformity, structure optimization, multi-functionality and sustainable development. This paper first expounds on the relationship among agricultural elements, structure, function and development theoretically, compartmentalizes agriculture types based on human-land elements matching, and depicts the development path of agricultural multi-functionality. it shows that the matching of human-land elements is a key to agricultural types, and the multi-functionality is an indication of agricultural development stages. At last, as a case study of Suzhou in eastern coastal area, the paper analyzes the evolvement situation and developing mechanism and some typical models of modern agriculture which suit to agriculture system evolvement. The results .show that in Suzhou the agriculture productivity, has improved greatly; And along with the agriculture structure optimizing, agriculture function has translated from ＂production ＂ to ＂non- production and production ＂. With simulation of agricultural trend in Suzhou, it is .found that Suzhou has a LP- dependence （labor productivity） on agricultural element, so Suzhou will has much more potential in land productivity. Based on the above analysis on agricultural system, some typical patterns on modern agriculture in Suzhou are brought up, such as export-oriented agriculture, enterprises-leading agriculture, science and technology, parks agriculture, stereoseopic agriculture, and tourism and sightseeing agriculture.
