The role of biosolar technologies in future energy supply making scenarios for the Netherlands: Energy port and energy farm

This paper assesses the possible roles of biosolar energy systems in the Netherlands in the coming years. The appraisal is made in the light of EU Directives on renewable energy and reduction of CO₂ emissions, and the new Dutch Energy Agreement for Sustainable Growth. The assessment is made within the Dutch BioSolar Cells (BSCs) research programme on photosynthesis and its application in fuel production. Part of the programme is committed to societal debate by considering different options and uses of biosolar technology. To provide building blocks for these discussions, we conducted a comprehensive desk study supplemented with key expert interviews, and we identified and articulated the main drivers for the Dutch transition towards more sustainable energy supply. Next, these drivers were used to develop two futures: energy port and energy farm, representing institutional settings in which BSC technology could be implemented. Both represent fundamentally different types of innovation and are useful in assessing the effect of policies on future energy systems. Both scenarios were used in workshops with BSC researchers and policymakers. Their possible implications for the BSC programme itself, as well as the broader policy significance of the use of biosolar technologies in the Netherlands, are indicated.     

Business cycle,storage, and energy prices

This study examines the effect of the state of the economy and inventory on interest-adjusted bases and expected returns for five energy commodities. We find that interest-adjusted bases and returns have a business cycle pattern. Consistent with the theory of storage, demand shocks near business cycle peaks generate negative interest-adjusted bases and positive returns. In recessions, the bases become positive, and the average returns are negative. Our regression results also show that the interest-adjusted bases of energy commodities are counter-cyclical and the expected returns are pro-cyclical. For petroleum commodities, inventory has a significant effect on interest-adjusted bases at low levels of inventory, whereas at high inventory levels the effect of inventory on the bases is weak. Finally, we find that the bases and economic conditions predict spot returns in energy commodity markets.     

Investigating volatility spillover of energy commodities in the context of the Chinese and European stock markets

This paper investigates spillover from energy commodities to Shanghai stock exchange and European Stock market, and identifies possible risks transmission and portfolio diversification opportunities. The study is conducted on daily spot prices of carbon (CO2) emission, natural gas and crude oil from 16 December 2010 to 29 December 2022, employing Granger causality test, dynamic conditional correlation (DCC), Diebold-Yilmaz (2012) and Barunik-Krehlic (2017) models. Results identify higher volatility and imply greater connectedness in the longer run. Additionally, natural gas is witnessed as the highest contributor of the shocks and crude oil as the highest receiver of the shocks from the network connection. Further results suggest for investment in energy commodities in shorter run rather than long run for efficient portfolio diversification. Results from this study are expected to have practical implications for portfolio managers, investors, and market regulators, given the suggestion of this study to incorporate energy stocks for efficient diversification of risk.     

基于ESCP范式下的我国新能源储能产业发展战略研究

在分析我国新能源储能产业发展现状的基础上,试图从产业环境和政府政策角度出发,改进并运用SCP框架,对当前我国新能源储能产业环境、市场结构、运营商策略行为、市场绩效以及储能产业政策进行综合分析。分析表明,目前我国新能源储能产业虽取得了一定的发展,但仍存在的国家重视力度不够、产业集中度过高、进入壁垒大、投资回报机制不健全技术人才缺乏、科技创新资金投入不足及产业规模偏小等问题,因此只有发现发展过程中所存在的问题,才能为储能产业的高效、健康、持续发展提供相关建议并制定出我国新能源储能产业发展战略。     

Asset pricing and energy consumption risk

This paper proposes energy consumption in the US as a new measure for the consumption capital asset pricing model. We find that (i) industrial energy growth produces reasonable values for the relative risk aversion coefficient and the implied risk-free rate; (ii) compared to alternative consumption measures, industrial energy performs well in explaining the cross-sectional variation in stock returns with the lowest implied risk aversion and pricing errors; (iii) the industrial energy consumption risk model performs equally well as the Fama–French three-factor model in the cross-sectional asset pricing tests; and (iv) total energy consumption risk is priced in the presence of the Fama–French factor risks.     

新能源汽车财务与非财务消息对股市影响的多维特征及差异

新能源汽车股市是投资者对公司财务绩效、政策导向、技术水平和发展前景等多方面因素综合反应的结果。将新能源汽车产业相关消息分为"财务"和"非财务"消息,应用事件研究法从"敏感性""、强弱性"和"持续性"三个维度分析了财务与非财务类消息对于新能源汽车股市影响的差异性。结果表明,新能源汽车非财务类消息对于股市表现影响的强度和持续性相对更显著。新能源汽车非财务类消息中的政策、市场消息对于股市表现影响的敏感性要高于技术消息,政策、技术消息对于股市表现影响的强度明显高于市场消息,技术消息对于股市表现影响的持续性明显优于政策和市场类消息。新能源汽车产业的政策扶持不应仅仅关注现阶段新能源汽车制造商的财务指标,更应高度关注新能源汽车制造商的创新能力。制造商要进一步加大新能源汽车的研发投入,通过资本市场的合理融资促进新能源汽车技术创新和长期盈利能力提升。     

能源效率、环境污染与中国经济发展方式转变

以往研究虽然关注了能源效率与经济发展之间的关系,但却忽略了能源利用过程中环境污染的改善对经济发展方式转变的影响。本文将环境变量纳入能源效率分析框架内,采用EBM-DEA模型测算了中国各地区能源效率,并利用动态空间面板模型,实证考察了环境约束下的能源效率对中国经济发展方式转变的影响。研究结果显示,中国经济发展方式具有明显的空间相关性和路径依赖性;与未考虑环境污染相比,环境约束下的能源效率对经济发展方式转变的影响更为明显,这也在一定程度上表明,如果不考虑能源效率提升的环境污染改善效应,将会低估其对经济发展方式转变的影响。本文结论为提升中国能源效率水平,加快经济发展方式转变提供政策启示。     

种养殖业保险发展问题分析

农业是国民经济的根基。但是占农业较大比重的种养殖业保险发展比较滞后的问题,削弱了保险服务经济社会的功效。虽然国家实施了一系列的政策性保险,但是种养殖业保险面临的风险较大、管理较弱、人才紧缺、环境不优的问题,限制了这一领域保险的健康快速发展。本文提出,现阶段要通过科学确立其发展模式,建立有效的风险分担机制,加强管理、优化环境,实现种养殖业保险的又好又快发展,服务农业产业发展大局。
