“一带一路”倡议提出以来,中国海外项目投资的广度、深度及力度都在不断拓展。凑组理论将所有事物视为复杂关系的动态演变,因而从发展过程及成员关系的角度探究不同海外投资项目的凑组模式,能解构项目凑组中的复杂性并减少不确定性,对于提高项目的风险规避能力、运营能力和盈利能力具有十分重要的意义。基于凑组理论,本文构建中国海外投资项目凑组的理论框架,并以中老铁路为例解析凑组模式。研究表明:① 海外投资项目可以通过技术、产业和市场等价值关联进行凑组,因而中国企业的海外投资可以采用“以一带多,核心集聚”的方式。② 海外投资项目的类型和领域越多样越广泛,项目凑组越完整越稳定。③ 凑组所形成的空间形态取决于项目的空间分布与项目间的价值关系,中老铁路表现为“走廊”式空间形态。④ 中老铁路具备形成项目凑组的条件,但后期技术需求的不确定及相关产业下游项目投资的缺乏,使中老铁路建设带来的延伸市场缺乏项目支撑。  相似文献

随着高速交通技术和移动基础设施的迅速发展,城市创新活动已经不再局限于特定的地理空间,在网络空间中彼此远离但有着较强经济活动关联的城市之间是否也可以实现协同创新,目前仍缺乏经验证据。基于2001—2016年中国289个地级市宏观面板数据和微观层面上市公司数据,采用社会网络分析法、工具变量法以及空间杜宾模型等方法,定量研究了集聚外部性与网络外部性对于城市创新发展的影响。结果显示:创新要素依旧存在着向头部企业和中心城市集中的趋势,且正是这种集中所带来的集聚外部性促进了城市的创新发展;城市可通过融入经济关联网络,借助于网络外部性来提高自身创新水平;就集聚外部性与网络外部性促进城市创新发展的传导机制来看,虽然政府科教支出水平、城市基础设施状况以及高铁网络的建设是集聚外部性与网络外部性发挥的重要条件,但经济活动密度的提升所带来的集聚外部性还可以强化网络外部性所带来的创新效应,而外商直接投资活动所分享的先进技术和管理经验则帮助网络外部性突破了地理空间的限制。因此,政府在探索城市创新发展路径的过程中,就无需囿于创新要素的空间集聚这一条路径,积极融入城市群内的国际科技创新中心建设,凭借网络外部性所分享的新知识与新技术,同样也能实现创新发展。  相似文献

随着改革开放的深入,港澳台及外商投资在珠三角地区产业转型过程中的弊端逐渐暴露,部分港澳台/外资企业成为区域发展新路径的阻碍,但已有研究对此讨论不足。因此,论文基于2000—2019年珠三角地区地级市行政区制造业的面板数据,构建了路径依赖与路径突破指数,通过固定面板回归模型,探究比较港澳台投资与外商投资对珠三角地区产业动态的影响。结果发现:港澳台投资有利于路径依赖型新产业出现,促进地方产业的相关多样化发展,更强的本地嵌入性是主要原因;外商投资则会降低地方产业路径突破的可能,并通过强化产业集中度,导致路径锁定。此外,政府补贴会强化外商投资的路径锁定效应。研究结论对完善产业演化理论和优化中国港澳台及外商投资政策导向具有重要启示。  相似文献

The Clean Development Mechanism (CDM) under the Kyoto Protocol allows industrialized countries to use credits from greenhouse gas (GHG) abatement projects in developing countries. A key requirement of the CDM is that the emission reductions be real, measurable and additional. This article evaluates how the additionality of CDM projects has been assessed in practice. The analysis is mainly based on a systematic evaluation of 93 registered CDM projects and comes to the conclusion that the current tools for demonstrating additionality are in need of substantial improvement. In particular, the application of the barrier analysis is highly subjective and difficult to validate in an objective and transparent manner. Key assumptions regarding additionality are often not substantiated with credible, documented evidence. In a considerable number of cases it is questionable whether the emission reductions are actually additional. Based on these findings, practical recommendations for improving the assessment of additionality are provided.  相似文献

Despite the importance of emissions trading and energy taxes to the EU and national climate strategies, limited research exists on their impact on emissions from the perspective of industry sectors targeted by economic instruments. This article contributes to redressing this deficit by critically analysing whether economic instruments applied within the UK provide sufficiently strong price incentives to overcome barriers to investment in energy-intensive sectors created by the capital and finance costs of replacing ‘legacy’ infrastructure and fluctuating base energy prices. Results from a survey of 189 companies from the cement, aluminium and chemicals sectors and 23 interviews with sector associations and businesses from these and other energy-intensive industries indicate that economic instruments have raised awareness of energy efficiency but have had a minimal impact on investment decisions. EU-wide economic instruments such as the EU emissions trading scheme have yet to be fully tested but may encounter similar difficulties. On this basis, we argue that economic instruments may need to be complemented by more interventionist programmes focusing on large-scale investment in energy modernization and we also discuss how economic instruments can contribute to this agenda.  相似文献

Technology transfer is often mentioned as an ancillary benefit of the Kyoto Protocol's Clean Development Mechanism (CDM), but this claim has hardly been researched or substantiated. The question of technology transfer is important, both for developing countries in need for new technology and knowledge and for industrialized countries, as it provides export potential for climate-friendly technologies. To determine what technology transfer means, whether it is occurring through the CDM, and what the value of the associated capital flows is, this article examines technology transfer in the 63 CDM projects that were registered up until 1 January 2006. Technology hardware originates from outside the host country in almost 50% of the evaluated projects, particularly in non-CO2 greenhouse gas projects, wind energy projects, and a substantial share of the hydropower projects. Bioenergy and projects in the agricultural sector mainly use local technology. The investment value associated with the CDM projects that transferred technology is estimated to be around €470 million, with about €390 million coming from the EU. As the non-CO2 greenhouse gas projects had very low capital costs, the investment value was highest in the more capital-intensive wind energy and hydropower projects. We also found substantial soft technology transfer, but uncertainties for this finding are greater.  相似文献

The direction of UK energy policy requires a renewed impetus if the goal of climate change stabilization is to be met. Cost is not the main issue: a transformation to a low-carbon energy system may be no more expensive than meeting future energy demands with fossil fuels. Institutional barriers are preventing the large-scale adoption of the necessary technologies. New institutions to promote low-carbon technologies have not yet led to investment on the necessary scale. Further changes to the operation of the UK electricity markets to create a ‘level playing field’ for small-scale and intermittent generation are necessary. UK policy can contribute to international agreements following on from the Kyoto Accord, which also need to address the institutional barriers to energy technology development and transfer.  相似文献

What potential effect do flexible mechanisms under the Kyoto Protocol have on energy efficiency, fuel switching and the development of renewable energy sources for the eight post-communist EU Member States that accessed in 2004? These countries are chief candidates for hosting Joint Implementation (JI) projects and for participating in international emission trading, which may assist the implementation and financing of projects in these target areas. The potentials and barriers to Joint Implementation are reviewed, as well as the conditions under which international emission trading can influence the energy use of the selling country. Different strategies adopted by the host countries towards the application of these instruments, and their impact on sustainable energy development, are examined. The article concludes that the Kyoto flexibility mechanisms may play a positive, but rather limited, role in the sustainable energy development of the region, but the barriers to Joint Implementation may shift the emphasis towards transactions under the framework of international emission trading. If innovative mechanisms are tied to sustainable development goals, this may mobilize the energyefficiency potentials of these countries. An attractive opportunity exists to achieve energy efficiency and emission reductions, utilizing the revenues from allowance sales through ‘green investment’ schemes.  相似文献

Land acquisitions are transforming land-use systems globally, and their characteristics and impacts on human well-being have been extensively analysed through local case studies and regional or global inventories. However, national-level analysis that is crucial for national policy on sustainable agricultural investments and land use is still lacking. This paper conducts an archetype analysis of a unique dataset on land concessions in Lao PDR to provide a national-scale assessment of the impacts of land acquisitions on human well-being in 294 affected villages. The results show that land acquisitions influence human well-being through 18 distinct pathways. These pathways describe how some land acquisitions enhance or maintain well-being, while others elicit adverse impacts or trade-offs between well-being dimensions, particularly food security, income, and livelihood resilience. They further reveal five archetypical processes that mediate the effects of land acquisitions on well-being through: (i) shifting access to land and natural resources; (ii) commercialization of agriculture; (iii) availability of development opportunities; (iv) environmental impacts; and (v) employment opportunities within and outside land acquisitions. These processes affect well-being by shaping livelihood portfolios and dependence on natural resources. The majority of land acquisitions trigger trade-offs or adverse impacts on well-being. The small number of villages where well-being increased despite the presence of land acquisitions were mainly shaped by narrow and rigid preconditions. The archetypical processes and the explanatory factors suggest that it is imperative to protect smallholders’ land-use rights and to avoid large-scale deals, as their adverse impacts outweigh opportunities and are more severe than the impacts of small-scale acquisitions. Employment opportunities may provide additional cash income but should not be exclusively relied upon.  相似文献
