油气勘探开发项目投资决策路径的设计

研究油气勘探开发项目投资决策路径的根本目的在于规避风险,以利润极大化为原则,兼顾社会目标,正确选择投资方向,合理安排投资规模,保证石油化工企业油气资源的持续安全供应和可持续发展,提高集团的竞争力.油气勘探开发项目具有明显的实物期权特性,传统的NPV方法已经不适应此类项目的评价与决策,本文结合中石化的实际,从企业目标和社会目标2个方面着手,提出了基于实物期权的油气勘探开发项目投资决策路径,从而丰富了项目投资决策的思路和方法.

Defending community? Indigeneity, self-determination and institutional ambivalence in the restoration of Lake Whakaki

Conservation practitioners have scrutinized the credibility and effectiveness of community-based natural resource management, noting its romantic misconceptions about communities and their capacities. Early approaches failed to acknowledge the heterogeneity of collective agents, the synergy between decentralization and neoliberalism, or the need to affirm rural peoples’ entitlements to resources. A Maori community’s attempt to restore Lake Whakaki on New Zealand’s east coast confirms many of these critiques. The restoration confronts institutional ambivalence, obstructive forces from beyond the zone of Maori influence and non-correspondence between community and catchment dynamics. Fulfilment of the project requires exogenous resources and authority, but state conservation agencies are ambivalent towards local demands for self-determined development. Nonetheless, an uncommon degree of agency which is grounded within community aspirations for sovereignty suggests that the motivational characteristics of community retain their importance in debates about integrated conservation and development.     

Re-orientation of the city plan: Strategic planning and design competition in China

Rather than being abandoned along with the demise of the centrally planned economy, city planning as a profession is flourishing in China. New hybrid plans such as strategic development plans (concept plans) have been invented, and the planning procedure has become more flexible. Design competition and planning consultancy are widespread. This paper examines the development of new strategic development plans and design competition. It is argued that city planning has been re-orientated from a technical rationale, i.e. allocating state development projects to the city, to the imperative derived from market-oriented development, i.e. consolidating competitiveness during inter-city competition. The contradiction between market and planning is that while the status of city planning has been raised and its approach is becoming more strategic, the actual functionality of city planning has become more instrumental.     

The future of industrial cities and regions in central and eastern Europe

Economic transition in central and eastern Europe (CEE) has had a particularly strong impact on industrial cities and regions. Following their economic collapse, most of them are now confronted with serious problems such as high unemployment and vast ecological damage. The paper presents findings from a pan European research project that investigated the problems of these cities and regions as well as the strategies being adopted to cope with structural change. It examines the differences in approaches and addresses the question whether existing EU policy is suitable for supporting the redevelopment of old industrial cities and regions in CEE countries. The paper concludes with recommendations for future directions in policy making.
