"北星双峰"工艺气相釜流型及料位的测量

利用声发射检测技术，根据颗粒运动碰撞壁面产生声波的机理以及声波信号随流化床高的规律性变化，发现“北星双峰”工艺的气相釜为带有滞留区的双循环流动模式。试验同时发现，扩大段部位声能量最小处或声信号能量及声信号均方差均达到最大处为料位，由此获得了一种简易快捷、安全环保的料位检测技术，为装置的“安稳长满优”运行提供了保障。     

Relative Value Relevance of the Successful Efforts and Full Cost Accounting Methods in the Oil and Gas Industry

This paper examines the value relevance of two alternative accounting methods for exploration and development (E&D) expenditures for oil and gas firms. I find that full cost (FC) accounting data is more value-relevant than successful efforts (SE) accounting data. Further analysis reveals that the smooth earnings provided by the FC method contributes to the higher value relevance of the FC method. This study concludes that a policy of full capitalization of expenditures with uncertain future economic benefits better summarizes information relevant to investors relative to a policy of partial capitalization.

Regulatory impact on voluntary climate change–related reporting by Australian government‐owned corporations

This paper concerns voluntary climate change–related reporting of government‐owned corporations (GOCs). We investigate whether the Australian National Gresenhouse and Energy Reporting Scheme (NGERS), a regulation stipulating the disclosure of greenhouse gas emissions to government, subsequently made publicly available on a Website, has a positive impact on the voluntary disclosure of climate change–related information not required by the regulation. We find that implementation of NGERS has a positive effect on voluntary climate change‐related disclosures by GOCs. Hence, mandating disclosure of organisations’ negative environmental performance, such as greenhouse gas emissions, can influence voluntary disclosures of a broad range of related information particularly in organisations that are not subject to capital markets incentives. However, upon later but concurrent implementation of a Carbon Tax after a highly partisan and divisive political debate, climate change–related disclosures by GOCs reduce, consistent with the de Villiers and van Staden (2006) argument that when disclosures might increase awareness of sensitive issues, avoidance of attention to the issue might be the best strategy to retain legitimacy.     

低碳绿色增长战略下韩国天然气产业发展及启示

韩国立足本国资源禀赋,围绕社会经济发展和民众关切,制定能源政策和发展规划,能源战略从早期的"供给导向"逐步转向"绿色低碳"。2019年,韩国《第三个国家能源总体规划(2020-2040)》提出将逐步退出核电,阶段性关停老小燃煤机组并禁止新建与扩建,加快发展风能和太阳能,2040年将可再生能源发电占比提高到35%,进一步提升天然气在能源结构中的地位。韩国天然气产业的发展立足引进LNG资源,LNG进口及管网设施建设长期坚持由国有控股公司--韩国天然气公司(KOGAS)主导经营,实行第三方协商准入;同时谨慎稳妥推进市场化改革,渐近式引入民间企业参与LNG资源引进,妥善解决韩国天然气公司持有的国际"照付不议"长期协议的资源采购合同问题。借鉴韩国的天然气产业发展经验,中国的"十四五"规划需全面把握世界能源绿色低碳发展大势,促进天然气消费;支持和引导各类企业"走出去"获取海外天然气资源;稳妥推进天然气结构重组和市场化改革;妥善解决天然气"照付不议"长期贸易合同问题,避免无序竞争;多措并举稳定供应,解决天然气应急调峰问题。     

我国推广天然气汽车的研究

石油短缺、生态恶化迫使人们寻求清洁替代能源。我国城市人口密度大,而天然气具有替代石油的资源潜力,这决定了我国推广天然气汽车的必要性和现实性。经过10年的试点,我国天然气汽车产业已具备诸多有利条件,但总体规模过小,尚处于发展的初步阶段。今后应重点解决好天然气资源利用、天然气汽车产业基础设施建设和天然气汽车关键技术等制约我国天然气汽车产业发展的主要问题。     

A classroom game on a negative externality correcting tax: Revenue return,regressivity, and the double dividend

The concept of negative externality is central to the teaching of environmental economics, but corrective taxes are almost always regressive. How exactly might governments return externality-correcting tax revenue to overcome regressivity and not alter marginal incentives? In addition, there is a desire to achieve a double dividend in the use of externality-correcting taxes, that is, to use the revenue to offset existing distortionary taxes, such as those on labor that produce a dead weight loss. In this article, the authors explain a classroom game that was developed for students to understand the theory of externalities, taxation dead weight loss, and regressivity. Then, the problem helps students explore the actual design of a policy that satisfies the double dividend hypothesis and corrects for regressivity.     

Greenhouse gas emission reduction potentials in air transport: a structural equation modelling-based multi-group analysis

In this study, we used a structural equation modelling (SEM) approach to identify the key factors that influence greenhouse gas (GHG) emission reduction potentials in air transport (ERPAT). We explored the correlations among constructs from the perspectives of aviation GHG emission reduction. Organisation type is one of the contextual factors that may change the nature of these correlations. Person- and self-administered questionnaires were used to collect data from 249 aviation experts. The results obtained using SEM showed that aircraft technology and design, aviation operations and infrastructure, socio-economic and policy measures, and alternative fuels and fuel properties are the key factors for reducing GHG emission. Conclusively, organisation type can help in controlling the relationship among the constructs. Thus, organisation type acts as a moderator in the research model. The outputs can be used to measure the level of knowledge and understanding regarding ERPAT and can provide policy-makers, government organisations, and airlines with valuable information for designing appropriate air transport policies for emission reduction.
