| 1 | Coordinated optimal dispatch and market equilibrium of integrated electric power and natural gas networks with P2G embedded显示文摘As power to gas(P2 G) technology gradually matures, the coupling between electricity networks and natural gas networks should ideally evolve synergistically.With the intent of characterizing market behaviors of integrated electric power and natural gas networks(IPGNs)with P2 G facilities, this paper establishes a steady-state model of P2 G and constructs optimal dispatch models of an electricity network and a natural gas network separately. In addition, a concept of slack energy flow(SEF) is proposed as a tool for coordinated optimal dispatch between the two networks. To study how the market pricing mechanism affects coordinated optimal dispatch in an IPGN, a market equilibrium-solving model for an IPGN is constructed according to game theory, with a solution based on the Nikaido-Isoda function. Case studies are conducted on a joint model that combines the modified IEEE 118-node electricity network and the Belgian 20-node gas network.The results show that if the game between an electric power company and a natural gas company reaches market equilibrium, not only can both companies maximize their profits, but also the coordinated operation of the coupling units, i.e., gas turbines and P2 G facilities, will contribute more to renewable energy utilization and carbon emission reduction. | Zexing CHEN Yongjun ZHANG Tianyao JI Zexiang CAI Licheng LI Zhiheng XU | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，3： | 37 |
| 2 | Purification,application and current market trend of natural graphite:A review显示文摘Graphite has a stacked planar sp2-hybridized C6 ring structure,displaying a polymorphism with rhombohedral,hexagonal,and turbostratic.Based on its structure-property relationship,it affords a variety of technologically innovative applications or performances in industries,such as lithium-ion batteries,fuel cells,two dimensional graphene,water purification,electronics,fiber optics,spintronics,refractories,electrical products,electric vehicles,etc.The monetary value of graphite depends largely on carbon content and flake size.However,the physical separation of graphite from its ore body is known to be very expensive,energy intensive and time-consuming.Hence,this study extensively describes a current purification method for producing high-quality graphite material with impurities reaching about 10–100 mg/kg,attracting a lot of end users.It also describes the potential applications of graphite materials and identifies the future scope of a new market,depending on material purity.Finally,the current and future graphite-mining countries are investigated in details. | Allah D.Jara Amha Betemariam Girma Woldetinsae Jung Yong Kim | 2019 | International Journal of Mining Science and Technology2019，29，5： | 17 |
| 3 | 谁是“高龄”农民工——基于流动人口监测调查的数据分析显示文摘年龄结构的改变对农民工传统两代次划分方式提出严峻挑战,精确合理的年龄划分方法是目前学术界的研究重点。本文引入机器学习中market basket analysis(购物篮分析法),利用2013-2015年国家卫生和计划生育委员会流动人口动态监测数据,从四大维度构建指标体系,通过多视角分析,进行'高龄'农民工的识别与界定。本文发现:农民工在45岁开始凸显'高龄'特征,在就业、医疗、收入等诸多方面受到挤压,不同于既有高龄农民工'50岁以上'的设定;以传统年龄界定制定农民工扶持与保障政策,会使农民工的需求与发展产生错位,不利于劳动力市场的资源配置与城镇化推进。据此,在明确'高龄'农民工群体及其特征后,提出相关政策建议。 | 靳小怡 胡钊源 顾东东 | 2018 | 管理评论2018，30，7： | 11 |

| 6 | Product market competition,ultimate controlling structure and related party transactions显示文摘Previous studies have shown that product market competition has an important effect on corporate strategies and internal governance mechanisms. Using a sample of China's listed firms from 2004 to 2009, we explore the relationship between product market competition and normal related party transactions and find a significant positive relationship. In addition, we investigate the substitutive effect of product market competition and the cash flow rights owned by ultimate controlling shareholders on the extent of normal related party transactions. In particular, our results suggest a positive relationship between the ultimate controlling shareholders' cash flow rights and normal related party transactions that is strongest in noncompetitive industries and weakens as product market competition increases. | Shenglan Chen Kun Wang Xiaoxue Li | 2012 | China Journal of Accounting Research2012，，4： | 7 |
| 7 | Recognition and analysis of potential risks in China's carbon emission trading markets显示文摘China formally launched the carbon trading pilots in seven provinces and cities in 2013.Based on the operating situations of international carbon emission trading markets and that in China,this study compares and analyzes the potential risks in the European Union Emission Trading Scheme,California’s cap-and-trade system,and the seven regional carbon trading pilots in China.It mainly recognizes market operation risks,risks of uncertain policy expectation,and risks of uncertain mechanism designs existing in China's carbon trading pilots.The carbon market risks are not good for the formation of rational price signals,making it difficult to guide enterprises on how to make low-carbon technology in-vestments.Such risks also affect the effectiveness and functions of carbon markets,which can lead to the non-achievement of national emission reduction goals.China has launched the national carbon emission trading scheme on December 19,2017.While building the national carbon trading scheme,it is important to fully refer to the experiences of international carbon markets and China's carbon trading pilots apart from strengthening the recognition,control,and supervision of carbon market risks.Doing so can promote the healthy development of China's na-tional carbon trading scheme. | DENG Mao-Zhi ZHANG Wen-Xiu | 2019 | Advances in Climate Change Research2019，10，1： | 7 |
| 8 | Optimal operation strategy for distributed battery aggregator providing energy and ancillary services显示文摘The high penetration of distributed renewable energy raises a higher concern for the safe and economic operation of the smart grid. Distributed batteries equipped in demand-side can not only contribute to the reliability and security of the grid, but also make profits by participating in the electricity market, especially when distributed batteries are combined and operated by an aggregator.Considering the well-operated mechanism of performance based regulation(PBR) in the U.S. electricity market, it becomes increasingly lucrative for batteries to participate not only in energy markets for energy arbitrage, but also in ancillary service markets to provide regulation and peakload shaving services. In this study, distributed batteries are operated and coordinated by the aggregator, which simultaneously submits offers to the energy and the ancillary service markets as an individual entity. An optimaldecision model is formulated for the aggregator to determine the operation and bidding strategy for the distributed batteries by considering the characteristics of batteries,including the terms of capacity, efficiency and degradation cost. Finally, a numerical case is conducted to evaluate the benefits of the decision model. | Kangning LIU Qixin CHEN Chongqing KANG Wei SU Guobin ZHONG | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，4： | 7 |

| 10 | The Impact of Farmland Transfers on Agricultural Investment in China:A Perspective of Transaction Cost Economics显示文摘There is growing concern that farmland transfers lead to less agricultural investment, which may adversely affect agricultural productivity growth in China.Prior research has primarily focused on the differences between owned cultivated land and rented plots,but little is known about how farmland transfers between relatives,which are popular in rural China,specifically affect agricultural investment.In this paper,we present a conceptual framework of transaction cost economics to compare different contracting strategies in China's farmland rental markets.As farmland rental markets in China are immature,land transfer between relatives establishes bilateral governance,which has the advantage of addressing the opportunistic activities of both parties and can ultimately increase investment by tenants.Based on data from two waves of household surveys,we empirically examine the impact of bilateral governance on the application of organic fertilizer,an indicator for agricultural investment.Our findings show that apart from economic factors, kinship is important to the functioning of farmland rental markets in rural areas. | Liangliang Gao Dingqiang Sun Cuiping Ma | 2019 | China & World Economy2019，27，1： | 6 |

| 12 | Coordinated scheduling model of power system with active distribution networks based on multi-agent system显示文摘With the large-scale development of distributed generations(DGs) and the connection into the main grid of active distribution networks(ADNs), traditional centralized dispatch of power system has encountered enormous challenge. In a bilateral electricity market, introducing ADN resources in the day-ahead generation schedule will not only enrich the dispatch patterns to the power system,but also reflect the initiative of ADNs. This paper proposes a coordinated scheduling model of power system with a plurality of ADNs based on multi-agent system where ADN agents are brought in the day-ahead market clearing.The process of market clearing and the dispatch of DGs in ADNs are independent with each other but linked together through the market clearing price(MCP) and bid volume.The optimal operating point of the whole system is achieved through multiple information exchange. In comparison with the dispatch without interaction between ADNs and the market operator(MO), the coordinated scheduling model is applied in a system with four ADNs to verify that the proposed method can improve the overall interests of ADNs. Finally, the effects of storage device and tie-line power limit are analyzed. | Jingzhe HU Hao CONG Chuanwen JIANG | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，3： | 6 |
| 13 | Investigating spatial distribution of tourist attractions’inlinks: A case study of three mountains显示文摘In hyperlink analysis,most researchers focus on interpreting hyperlink counts,they seldom concern themselves enough about the significance of spatial distribution of hyperlinks.In this paper,we argue that not only can the inlink count to a tourist attraction’s official website reflect its attractiveness,but also the spatial distribution of its inlinks can reflect the distribution of its tourist source markets.Three mountains in Anhui Province,China,are chosen for the case study.Firstly,the correlation between the spatial distributions of an attraction’s tourist source markets and its official website’s inlinks is investigated.Secondly,the tourism indexes such as the spatial concentration index(SCI)and the attraction radius(AR),which are calculated by inlinks,are compared to the real indexes based on tourist sources.Last,the detailed discussion and analysis are presented and an improved model,which is used to calculate the distribution of inlinks,is proposed. | ZHANG Yi 1,QI LiNa 2,YANG AnRan 1,SHI Lei 1 & XU Li 1 1 Institute of RS and GIS,Peking University,Beijing 100871,China 2 Center for Recreation and Tourism Research,Peking University,Beijing 100871,China | 2010 | Science China(Technological Sciences)2010，53，S1： | 5 |
| 14 | What Determines China's Grain Imports and Self-sufficiency? The Role of Rising Domestic Costs and Varying World Market Prices显示文摘China s grain sectors have faced unprecedented challenges in recent years as the ever-increasing and historically high level of grain output has failed to reduce grain imports. On the contrary, high grain imports and high domestic stock have accompanied historically high domestic output, a situation dubbed the 'triple high' phenomenon in current policy discussion. This paper explores the role of widening domestic-world market price gaps in determining the triple high phenomenon.Unlike earlier studies that relied on production capacities, this paper argues that domestic production and demand (hence imports) are functions of domestic and world market prices and proposes an analytical framework to explicitly capture such price gaps under restricted trade linkages in general equilibrium. Following this approach, a set of price scenarios for the 2011-2020 period are constructed and simulated in a computable general equilibrium model. Results from the core scenarios, in which recent domestic and world market price trends are assumed to continue, suggest that further widening price gaps would substantially increase grain imports and reduce domestic output (by 60 million tons) and self-sufficiency ratios from base levels. In the alternative scenarios with larger (smaller) price gaps, we find higher (lower) imports and larger (smaller) decreases in domestic output and self-sufficiency ratios. Such results provide important policy implications as China's agricultural policy undergoes significant adjustment. | Wusheng Yu Tianxiang Li Jing Zhu | 2019 | China & World Economy2019，27，5： | 5 |

| 16 | Interchange between grooming and infant handling in female Tibetan macaques(Macaca thibetana)显示文摘In some non-human primates, infants function as a social tool that can bridge relationships among group members. Infants are a desired commodity for group members, and mothers control access to them. The biological market theory suggests that grooming is widespread and represents a commodity that can be exchanged for infant handling. As a limited resource, however, the extent to which infants are interchanged between mothers(females with an infant) and non-mothers(potential handlers,females without an infant) remains unclear. In this study, we collected behavioral data to investigate the relationship between grooming and infant handling in free-ranging Tibetan macaques(Macaca thibetana)at Mt. Huangshan, China. Our results showed that females with infants received more grooming than females without infants. After her infant was handled,mother females received more grooming than they did during daily grooming interactions. However, with the increasing number of infants within the social group, both the grooming that mothers received and the grooming that non-mothers invested for handling infants decreased. We also found that non-mothers invested more time in grooming to gain access to younger infants than older infants. Our results provide evidence that infants are social commodities for both mother and non-mother females. Mothers use infants for obtain grooming and non-mothers use grooming to gain access to infants. The current study implies a bidirectional and complex interchange pattern between grooming and infant handling to compensate for the dyadic grooming disparity in non-human primates. | Qi Jiang Dong-Po Xia Xi Wang Dao Zhang Bing-Hua Sun Jin-Hua Li | 2019 | Zoological Research2019，40，2： | 4 |
| 17 | Energy and economic impacts of an international multi-regional carbon market显示文摘The establishment of a global multi-regional carbon market is considered to be a cost effective approach to facilitate global emission abatement and has been widely concerned.The ongoing planned linkage between the European Union's carbon market and a new emission trading system in Australia in 2015 would be an important attempt to the practice of building up an international carbon market across different regions.To understand the abatement effect of such a global carbon market and to study its energy and economic impact on different market participants,this article adopts a global dynamic computable general equilibrium model with a detailed representation of the interactions between energy and economic systems.Our model includes 20 economic sectors and 19 regions,and describes in detail 17 energy technologies.Bundled with fossil fuel consumptions,the emission permits are considered to be essential inputs in each of the production and consumption activities in the economic system to simulate global carbon market policies.Carbon emission permits are endogenously set in the model,and can be traded between sectors and regions.Considering the current development of the global carbon market,this study takes 2020 as the study period.Four scenarios(reference scenario,independent carbon market scenario,Europe Union(EUh-Australia scenario,and China-EU-Australia scenario) are designed to evaluate the impact of the global carbon market involving China,the EU,and Australia.We find that the carbon price in the three countries varies a lot,from $32/tCO_2 in Australia,to $17.5/tCO_2 in the EU,and to $10/tCO_2 in China.Though the relative emission reduction(3%) in China is lower than that in the EU(9%) and Australia(18%),the absolute emission reduction in China is far greater than that in the EU and Australia.When China is included in the carbon market,which already includes the EU and Australia,the prevailing global carbon price falls from $22 per ton carbon dioxide(CO_2) to $12/tCO_2,due to the relatively lower abatement cost in China.Seventy-one percent of the EU's and eighty-one percent of Australia's domestic reduction burden would be transferred to China,increasing 0.03%of the EU's and 0.06%of Australia's welfare.The emission constraint improves the energy efficiency of China's industry sector by 1.4%,reduces coal consumption by3.3%,and increases clean energy by 3.5%. | Tianyu Qi Yuanzhe Yang Xiliang Zhang | 2015 | Chinese Journal of Population,Resources and Environment2015，13，1： | 3 |

| 19 | A Game Theoretic Approach for Hierarchical Caching Resource Sharing in 5G Networks with Virtualization显示文摘Caching and virtualization have been considered as the promising techniques in 5G Networks. In 5G networks with virtualization, the caching resources deployed by infrastructure providers (InPs) can be abstracted into isolated slices and transparently shared by mobile virtual network operators (MVNOs). In this case, one of the most important issues is how the MVNOs to share the caching resource. To solve this issue, different from previous works, a hierarchical caching architecture that core network and radio access network (RAN) have the caching capability in 5G networks with virtualization is first considered in this paper. Then, we study the problem of hierarchical caching resource sharing for MVNOs, and a competitive game to maximize their expectation revenue based on the oligopoly market model is formulated. As it is a hard problem to find the optimal solution in the hierarchical caching resource sharing problem, we decompose the optimization problem into two independent caching resource sharing problems in RAN and core network, respectively. Then the local optimal solutions are solved and the global Nash equilibrium solution is achieved. Finally, simulation results are illustrated to demonstrate the performance of the proposed scheme. | Renchao Xie Jun Wu Rui Wang Tao Huang | 2019 | China Communications2019，16，7： | 3 |
| 20 | A Stackelberg game approach for demand response management of multi-microgrids with overlapping sales areas显示文摘Microgrids are increasingly participating directly in the electricity market as sellers in order to fulfill the power demand in specific regions.In this study,we consider a demand response management model for multi-microgrids and multi-users,with overlapping sales areas.We construct a Stackelberg game model of microgrids and users,and then analyze the equilibrium strategies systematically.As such,we prove that there is a unique Stackelberg equilibrium solution for the game.In equilibrium,the electricity price strategies of the microgrids and the demand strategies of the users achieve a balance.Furthermore,we propose a numerical algorithm,supported by a simulation,to compute the equilibrium solution and give the proof of convergence. | Jun LI Guangqing MA Tao LI Wushun CHEN Yu GU | 2019 | Science China(Information Sciences)2019，62，11： | 3 |
