工资对产业结构升级的影响——基于中国经济数据的分析 总被引:1,自引:0,他引:1
经济增长过程中伴随着产业结构的优化升级。工资不但可以通过工资差异激励劳动力从低效率产业向高效率产业流动,推动产业结构升级,而且可以通过改变消费结构和投资结构进而影响产业结构演变,并为产业结构升级储备高级人才。本文对中国改革开放以来的工资与产业结构的经济数据进行实证研究得出:工资与产业结构之间是正向的相关关系,且两者之间存在双向因果关系。因此,工资水平的提高在一定程度上促进了产业结构的优化升级。 相似文献

Backcasting has been widely used for developing energy futures. This paper explores the potential for using industrial ecology to guide the development of energy futures within a backcasting framework. Building on the backcasting work of Robinson [1], a seven step method is presented to embed industrial ecology principles within the development and assessment of future scenarios and transition paths toward them. The approach is applied to the case of backcasting regional energy futures in the Latrobe Valley, near Melbourne, Australia. This region has substantial brown coal deposits which are currently mined and used in coal-fired power stations to generate electricity. Bounded by a sustainability vision for the region in a carbon-constrained world, regional industrial ecologies in 2050 were backcast around three themes: bio-industries and renewables (no coal usage); electricity from coal with carbon capture and storage (low to high coal usage); and coal to products such as hydrogen, ammonia, diesel, methanol, plastics and char (demonstrating medium to high overall coal use relative to current levels). Potential environmental, technological, socio-political and economic impacts of each scenario across various life cycle stages were characterised. Results offer a platform for regional policy development to underpin deliberation on a preferred future by the community, industry and other stakeholders. Industrial ecology principles were found to be useful in backcasting for creatively articulating alternative futures featuring industrial symbiosis. However, enabling the approach to guide implementation of sustainable transition pathways requires further development and would benefit from integration within the Strategic Sustainable Development framework of Robèrt et al. [2]. 相似文献

The industrial landscape is becoming increasingly complex and dynamic, with innovative technologies stimulating the emergence of new applications, business models and industries. This paper presents a framework for mapping science and technology-based industrial emergence, in order to better understand the nature and characteristics of such phenomena, as a basis for improved strategy development. A full lifecycle perspective is included, emphasizing early stage phases associated with scientific and technological developments, together with key transitions between phases related to the conversion of scientific knowledge to technological capability, application, industrial activity and economic value. Roadmapping concepts are used to map industrial emergence phenomena from various perspectives that cover value creation and capture activities together with demand and supply-side factors. The framework has been tested by developing more than 25 diverse ‘emergence maps’ of historical industrial evolution, building confidence that the framework might be applicable to current and future emergence. Common characteristics of industrial emergence have been identified, including key events and milestones, focusing on a chain of demonstrators that delineate the various phases and transitions. 相似文献

本文基于行动者—网络理论从技术变化、媒介信息融合导致产业利益冲突的这一视角出发,分析由国家、产业管理部门、产业的企事业单位以及社会公众围绕媒介信息技术的变化所构成的网络关系,在此基础上认为在国家、产业管理部门、产业的企事业单位以及社会公众与媒介信息技术的互动过程中有效实现各方利益的有机整合是实现"三网融合"的充分必要条件,而对广播电视和电信产业进行产业规制制度改革是有机整合各方利益的关键所在。 相似文献

产业转移的新经济地理学解释 总被引:2,自引:0,他引:2
丁建军 《中南财经政法大学学报》2011,(1)
不同于传统的产业转移理论,新经济地理学在规模报酬和垄断竞争框架下解释了产业转移现象,认为产业转移的基础不必然是第一自然的差异,在完全相同的均质空间下,由于市场接近效应、生活成本效应和市场拥挤效应所构成的集聚力和扩散力的相互作用,产业转移也会发生,并且表现出突发性、自我强化、预期自我实现和价值链环节分离的特性及关联度弱的产业先转移等规律。此外,新经济地理学还运用一般均衡分析方法考察了产业转移的福利效应,包括瓦尔拉斯效应、生产租金和规模区位效应、累积效应以及转移效应,并对影响产业转移的税收优惠竞争、公共基础设施改善和区域补贴等政策措施的效果进行了剖析。 相似文献

Does the country-of-origin effect matter to industrial brand equity in international business-to-business (B2B) markets? The effect of a product's country-of-origin (COO) on both industrial buyers' and consumers' perceptions and evaluations has been one of the most widely studied phenomena in the fields of international business, marketing, and consumer behavior since the 1960s. Although many country-of-origin studies focus on consumer behavior in developed countries and acknowledge that the processes and stages of economic development by which consumers use COO information may differ in developing countries, the fact that there has been little research to investigate the effects of COO could explain the variations in international buyers' evaluations of industrial brand equity in the newly-industrialized economies, such as Taiwan. Taiwanese firms are now formidable global B2B market players by successfully transforming themselves from manufacturing mainly low-value and labor-intensive goods to producing many high value-added products that require advanced technology, equipment and significant business expertise. With the adoption of advanced technology and equipment, an important question is whether unique and innovative fastener products from Taiwan have generated the country-of-origin effects in international B2B buyers' minds. The main finding is that the country-of-origin of fasteners has not yet become an important antecedent of industrial brand equity in the case of the fastener industry in Taiwan. 相似文献

外贸商品结构合理性评价指标的构建及实证研究 总被引:1,自引:0,他引:1
文章立足国情,在界定外贸商品结构合理性涵义的基础上,确立了以是否符合产业结构的改善和经济发展的需要为合理性的判断标准,以求克服盲目追求外贸商品结构高级化的弊端。在比较现有研究方法的基础上选择投入产出分析法,运用改进后的影响力系数和推动力系数,重新构造了进出口商品结构合理度指数和调整指数,并利用1997年、2002年和2007年的中国投入产出表计算了相关的评价指标,对我国近10年来的进出口商品结构合理性进行分析,发现我国的外贸商品结构合理度呈先扬后抑的趋势,说明其合理性有待改进,最后依据结论提出了调整我国外贸商品结构合理化的对策。 相似文献
