In this paper, under a dual-channel supply chain consisting of a manufacturer and multiple retailers, we investigate vertical and horizontal information sharing in different channel structures and the manufacturer’s choice on whether or not to keep a direct channel. To this end, we first study the dual-channel structure where uncertain demand is a linear function of price with a generalised-distribution base demand and show that the retailers have incentives to share information horizontally but not vertically, while the manufacturer is better off with vertical information sharing but its expected profit is not affected by horizontal information sharing. We next examine the retail-channel structure and find the basic results remain unchanged. Finally, we provide closed-form internal and external conditions under which the manufacturer can benefit from owning a dual-channel structure. Our study extends the existing literature by combining information sharing and dual-channel choice, introducing channel difference, discussing the impact of channel structure on horizontal and vertical sharing as well as providing interesting managerial insights for channel choice.

For any kind of economy activity in today's human society, one important factor which cannot be ignored is the energy. It may be said that there is no human beings'today's development without energy. However, most environmental issues does appear as energy be used in human activities, e.g. acid rain formation, green house gas increasing by using fossil fuels, and un-renewable resources exhaustion by the corresponding primary energy overused, etc.. In this case, one kind of theoretical Integrated Input-output Table, in which the energy be especially considered, be designed on the basis of our Integrated Input-output Accounting Framework of Natural Resources-Economy-Environment[6] [7], and the relevant Input-output models be also set up, in this paper.As application, one new and concrete Energy-Natural Resources-Economy-Environmental Input-Output Table-Chinese'92 Energy-Economy-Environmental Input-Output Table be put forward in this paper, and scenario forecasting and analysis for Chinese energy-resourceseconomy-environment (1992-2020) be given, too, in light of Chinese 1992 Input-output Table (Value), Chinese Statistics Year Book, Chinese Energy Balance etc..

The study of joint advertising channels decision-making is a very difficult issue. It mainly focuses on ads investment game between a manufacturer and a retailer in a vertical supply chain. With the rise of the game theory, scholars have been starting to investigate this issue in the frame of game theory in recent years. The paper improves the existing mod-els and introduces single-period and multi-period modified models. The paper obtains the closed-form solutions to the single-period model and the simulation results of the multi-period model. We also examine the implications of these results and obtain some insights into the real practice.

On the basis of the general framework of United Nations' "indirect/satellite" accounting system—Integrated System of Environment & Economy Accounting SEEA (1992) and 93' SNA, this paper tries to construct one simple. effective and practical CSEEA, and thereby trial estimates the l992 Chinese environmental adjusted GDP (Green GDP), under Chinese National Accounting System's reform practice.
