文章从系统工程学角度,基于R&D机构数、R&D人员数、R&D经费投入总额、GDP和科研专利授权量等数据,构建AHP-OVP模型,对粤港澳大湾区海洋科技产业合作潜力进行评价。结果发现:粤港澳大湾区海洋科技合作潜力层次分明,具有“两头小,中间大”的特点,香港与湾区内任一城市合作都能实现很好的契合度,是大湾区城市群海洋科技发展增长极,广州和深圳科研基础较为优越,应在增强自身海洋科技能力的同时帮助周边城市融入粤港澳大湾区海洋科技合作网络。促进大湾区海洋科技产业合作,应建立“核心 外围”式区域产业布局,发挥政府对海洋科技产业链培育的良性引导作用,完善以海洋技术咨询、海洋技术交易、风险资本市场、人才和信息沟通等为主要内容的大湾区城市群服务网络。  相似文献

Based on the basic trade gravity model and Xinjiang's practical situation, new explanatory variables (GDP, GDPpc and SCO) are introduced to build an extended trade gravity model fitting for Xinjiang's bilateral trade. From the empirical analysis of this model, it is proposed that those three variables affect the Xinjiang's bilateral trade positively. Whereas, geographic distance is found to be a significant factor influencing Xinjiang's bilateral trade negatively. Then, by the extended trade gravity model, this article analyzes the present trade situation between Xinjiang and its main trade partners quantitatively in 2004. The results indicate that Xinjiang cooperates with its most trade partners successfully in terms of present economic scale and developing level. Xinjiang has established successfully trade part- nership with Central Asia, Central Europe and Eastern Europe, Western Europe, East Asia and South Asia. However, the foreign trade development with West Asia is much slower. Finally, some suggestions on developing Xinjiang's foreign trade are put forward.  相似文献

Jensen, Kr. M. and Jensen R. Helkiær: En landbrugsgeografisk analyse af Gadbjerg og Givskud sogne. Geografisk Tidsskrift 76: 34—51. København juni 1. 1977.

The agricultural development in two parishes in a former heath region in Central Jylland has been investigated. The expansion of farmland up to the turn of the century was especially in Givskud replaced by a regression period with afforestation of marginal areas. The farmers are now increasing the size of their holdings and the specialization on few crops involves a more uniform land-use.  相似文献

Private property rights, such as individual transferable quotas, are thought to encourage fishers to act as resource stewards. To achieve this, however, fishers must be able to cooperate with each other. This paper examines the relationship between trust, cooperation and stewardship in five abalone (Haliotis) fisheries in southeastern Australia. Industry-led resource management initiatives are used as indicators of stewardship, sometimes including substantial sacrifice of catch quota. Higher levels of trust and cooperative capacity enabled greater levels of industry-based resource management in four of the five fisheries. In one case, however, high levels of trust and cooperative capacity did not translate into associated levels of resource management. It is suggested that additional factors, such as perceptions of resource condition, are key determinants of resource stewardship. Private property rights may, therefore, be less important than previously argued.  相似文献

The recent assessment by the Intergovernmental Panel on Climate Change (IPCC) has emphasized that understanding the institutional context in which policies are made and implemented is critical to define sustainable development paths from a climate change perspective. Nevertheless, while the importance of social, political and cultural factors is getting more recognition in some parts of the world, little is known about the human dimensions or the contexts in which they operate in the affluent oil economies of the Arabian Peninsula. Policies that implicitly subsidize or support a wasteful and environmentally destructive use of resources are still pervasive, while noteworthy environmental improvements still face formidable political and institutional constraints to the adaptation of the necessary far reaching and multisectoral approach. The principal aim of this paper is to identify some of the major shortcomings within the special context of the Arab Gulf states' socio-cultural environment in support of appropriate development pathways. Conclusions highlight that past and current policy recommendations for mitigating environmental threats are likely to be ineffective. This is because they are based on the unverified assumption that Western-derived standards of conduct, specifically the normative concept of ”good governance” and ”democracy”, will be adopted in non-Western politico-cultural contexts.  相似文献
