Divisia Decomposition Method and Its Application to Changes of Net Oil Import Intensity简

The existing oil import dependence index cannot exactly measure the economic cost or scales, and it is difficult to describe the economical aspect of oil security. To measure the foreign dependence of one country's economy and reflect its oil economic security, this paper defines the net oil import intensity as the ratio of net oil import cost to GDP. By using Divisia Index Decomposition, the change of net oil import intensity in five industrialized countries and five newly industrialized countries during 1971—2010 is decomposed into five factors: oil price, oil intensity, oil self-sufficiency, domestic price level and exchange rate. The result shows that the dominating factors are oil price and oil intensity; moreover, the newly industrialized countries have higher net oil import intensity than industrialized countries.

Decision-making model for risk management of cascade hydropower stations

In a medium-term electricity market,in order to reduce the risks of price and inflow uncertainties, the cascade hydropower stations may use the options contract with electricity supply companies. A profit-based model for risk management of cascade hydropower stations in the medium-term electricity market is presented. The objective function is profit maximization of cascade hydropower stations. In order to avoid the risks of price and inflow uncertainties, two different risk-aversion constraints: a minimum profit constraint and a minimum conditional value-at-risk, are introduced in the model. In addition, the model takes into account technology constraints of the generating units, which includes reservoir flow balance, reservoir capacity limits, water discharge constraints, etc. The model is formulated as a mixed integer nonlinear programming problem. Because the search space of the solution is very large, a genetic algorithm is used to deal with the problem.

考虑期权合约的电力市场纳什-古诺均衡分析

Option contract is one of the most important instruments for power generators developing bidding strategies and hedging market risk. Based on the peculiarities of bid-based-pool （BBP） power markets, a joint two-stage Cournot equilibrium model for option and spot markets is developed, and analytical formulas for market equilibrium are derived using a backward induction method. The impacts of option contract on efficiency of electricity markets and the behaviors of strategic generators are analyzed. The results show that strategic generators will voluntarily participate in strategic option contracting, and the existence of option contract accelerates the degree of competitive intensity in electricity markets and mitigates the market power abuse of generators to a large extent. In order to retain high spot market price and stable revenues, generators are interested in holding extremely high volatility of spot market price.

Price leadership strategy or branding strategy:an empirical test of indigenous Chinese exporters

The effects of price leadership strategies and branding strategies on the export performance of indigenous Chinese exporters with a focus on developing country markets and developed country markets are examined based on the principles of strategy-environment co-alignment and marketing segmentation theory. Findings suggest that when focusing on developing country markets, the use of a branding strategy is more likely to enhance export performance. When focusing on developed country markets, neither the use of a price leadership strategy nor the use of a branding strategy enhances export performance. Finally, theoretical and managerial implications of the findings are discussed.

Allocation of fixed transmission cost based on power flow tracing algorithm

1 Introduction a In the electricity market, because the calculation of the traditional spot electricity price according to node transmission charging is based upon short-run marginal cost, it is impossible to recover the great one-off investment of the transmission network, and this results in the payment imbalance of the electric network. Therefore, such spot electricity price goes against and its modification is indispensable to the development of the power system, and it is necessary to mod…     

Beyond cultural specific？ Cross-cultural management in the context of globalization： General trends and psychological implications

By reviewing evaluations collected via interviews from supervisors and employees in different companies, the author tries to pinpoint the extent to which a given corporate culture is applicable in a different cultural context. These studies present the results from really HR-audits. The study deals with the influence of corporate culture. This case study is about a German establishment in the United States （mechanical engineering industry）. The results clearly reveal that the acceptance of a corporate culture in a foreign cultural context is very low among the employees of the host country, regardless of the cultural patterns in the individual cases. The attempt to implement at any price a given concept of motivation programs and human resources development measures has held negative effects instead of positive effects on work efficiency and on the commitment of staff. The results will be critically analyzed. Psychological implications will be worked out and general trends are discussed.

A Generation Pricing Method with Capacity Bidding

Due to historic reasons China encounters some special difficulties in ESI(electricity system industry) restructureing,An easy and simple electricity value equivalent(es-EVE) method for day-ahead pool purchase pricing of China is therefore presented in this paper.The es-EVE method is different from two-part and one-part tariffs.It is more like the UK‘s method in form,but revised for China with some new concepts and procedure.The main contributions of it include:(1) Find two kinds of eigenvalue,namely EVEs,in an optimization model.(2) Define new concepts of virtual units units and feasible region,(3) Twice merit orderings are employed successively to find marginal price.They are simple maximum and minimum comparison procedures and so on.The special economic significance of the method for China is discussed.and some suggestion for ESI Restructuring based on es-EVE method are provided.A case study is offered at the end of the paper.
