基于油气资源开发视角的西部区域经济发展战略设计

我国西部地区是油气资源富集地区,但资源优势未能转化为产业优势,西部地区的经济发展一定程度上呈现出“资源诅咒”特征。作者根据比较优势原理,在分析西部地区资源状况、生产能力和技术水平的基础上,以形成石油天然气产业集群为目标,设计了西部地区经济发展的资源开发利用战略、产业发展战略、区域创新战略以及矿权、税费与用地制度创新战略。

南海油气资源开发研究--基于石油安全的视角

石油是不可再生的重要能源资源,在经济和社会发展中具有不可替代的重要作用。随着我国经济的快速发展和世界油价的不断攀升,石油供需矛盾日益突出,石油安全面临着严峻挑战。在陆地油气资源日渐枯竭的背景下,开发海洋油气资源已成为人类的必然选择。在我国四大海区中南海不仅海域面积辽阔,而且油气资源蕴藏丰富,开发潜力巨大,开发南海资源,对保障我国能源安全和维护国家海洋权利具有重要的战略意义。加快南海开发步伐,不仅需要国家从战略层面制定中长期规划、加大开发力度,而且要提高自主创新能力,在深海勘探、生产和运输等关键技术领域实现突破;还要妥善处理好与周边国家的关系,在致力于最终解决南海争议的同时,探讨共同开发的有效机制。     

电改环境下油气管道企业用电成本管控研究

电力体制改革为油气管道企业用电成本管控提供了政策支持。在梳理电力改革政策的基础上,简要介绍了适用于油气管道企业的新电力政策,详细分析了我国油气管道企业存在的基本电费偏高、力调电费偏高、用电类型不合理、用电管理有待完善等用电现状及其根本原因。在上述分析的基础上,提出了选取合适的用电类别、选择合理的电费计费方式降低基本电费、提高功率因数降低力调电费、积极利用直购电政策、健全用电成本管控激励和考核机制等对策建议,以期为油气管道企业用电成本管控提供参考借鉴。     

Assessing the Reliability of Self‐reported Income Information in Informal Small Business Lending through a Bogus Pipeline Experiment

Coping with asymmetric information plays a major role in successful small business lending. Our purpose is to determine if small business applicants report their income information correctly when requesting a loan. We use a randomised controlled trial bogus pipeline experiment, established during a typical cash‐flow analysis of a bank for small businesses in the Philippines. The bogus pipeline approach is commonly applied in social science and aims to increase the rate of truth telling by informing participants that answers will be verified by a lie detector. The experimental data, which include 243 observations of credit clients that are mainly from the agricultural and food value chain, served to identify asymmetric information. Additionally, debtors’ repayment behaviour for approved loans was observed by the bank. Our results indicate that loan applicants of the treatment group report lower incomes, an effect which is most pronounced in lower income quantile. Our analyses also reveal higher loan delinquencies in the control group.     

Alternatives to local content requirements in resource-rich countries

This paper discusses whether and to what extent resource-rich developing countries should introduce local content policies, i.e. requirements to include local inputs in petroleum extraction activities of multinational corporations. We argue that local content needs to be seen as a public expenditure question, since local content requirements increase multinational costs, and hence reduce the taxes which can be extracted from these companies. This implies that there are opportunity costs in imposing local content requirements, since the forgone taxes can be used in others ways which could potentially do more to improve development prospects. Moreover, past experiences of resource-rich developing countries suggest that local content policies can exacerbate key problems of patronage and rent-seeking which resource rents generate, increasing the chance that the resource wealth will prevent rather than help development. These arguments suggest that an optimal local content policy in the context of flawed institutions is a more limited one than those typically pursued by developing countries with recently discovered petroleum reserves. Using qualitative data from Tanzania, a country with recent discoveries of substantial natural gas deposits, we analyze why local content tends to become such a central issue in debates and policy processes, despite its potentially problematic aspects.     

中水源热泵地板供暖运行策略分析

为研究中水源热泵地板供暖系统的节能策略,以石家庄市某实际运行小区的中水源热泵地板辐射供暖系统为对象,引入室外综合温度的概念,综合考虑室外气温、太阳辐射热与风速等环境因子的影响,推导得出了地板辐射供暖系统质调节情况下,保证热用户舒适度的二次网供、回水温度调节公式。经实际运行测试,由该调节公式计算得出的二次网供、回水温度作为地板辐射供暖系统分时段质调节的依据,可以在满足热用户舒适度要求的情况下,取得良好的节能效果。中水源热泵系统与地板辐射供暖系统的结合及推广为城市集中供热提供了新思路。     

The Relationship Between Energy Commodity Prices and Electricity and Market Index Performances: Evidence from an Emerging Market

We investigate the effect of energy commodity price movements on market and electricity index returns in Turkey for the periods before, during, and after the year 2008. Although the Turkish economy is highly reliant on oil, we find that oil price does not lead either electricity or market indexes. This might be attributable to sluggish integration of financial markets in Turkey compared to developed markets. Natural gas price leads electricity index in the pre-2008 period. Its significance is reduced following the decline in natural gas usage in electricity production. This suggests that commodity dependence may be driving the link between commodity and asset prices in related sectors.     

A regression discontinuity approach to measuring the effectiveness of oil and natural gas regulation to address the common-pool externality

Oil and natural gas reservoirs typically span multiple productive leases so that no owner has rights to the entire stock of resource, resulting in production externalities. Previous literature has examined the effectiveness of government regulation in Texas and Oklahoma in abating these externalities, finding Oklahoma to be more successful in unifying common pools and securing property rights. Using regression discontinuity design, we quantify the impact of regulatory difference between the two states. We find that Oklahoma produces an average of 3361 more barrels of oil over the life of a well, relative to Texas. Given the maturity of the fields in question, the result underscores the continuing importance of addressing common pool externalities even after the primary phase of recovery has largely been completed.
