This paper presents the first single stage by binary tree model cash bond and stock, bond of cash and stock portfolio analysis, probability formula is deduced and the combination of the average value of the formula derived. Then the period of N binary tree analysis, considering the moment - 1 from N a node into two nodes moments N any one of the last, the bifurcation as one by one the look of a binary tree is calculated, the first time the contingent claim N, and use the value of the price of binary tree graph and the development process of the value of portfolio, N - 1 () function of time, by analogy, from each layer can be launched in front of a node and its value, use derived from forward gradually after the principle, the value of options available last binary tree roots of single node

The popularity of e-commerce is an inevitable trend, it is not only a sales channel, a new production management way, and will bring a commercial revolution. Schumpeter, with "the new production function, market and enterprises need to update and new business model to replace the old commercial mode, this process is called him" creative destruction ".Based on the basic composition of traditional enterprise business model based on the analysis of the system, from the business mode, and discussed the three layers of e-commerce enterprises for its intrinsic business model, and the influence of traditional enterprise success of e-business two case analysis, further study of the enterprise electronic commerce business model, how to traditional inherent e-commerce enterprises of the level of its final stages division, how to develop e-business, puts forward some countermeasures and Suggestions. Think with the traditional enterprise develop e-commerce, its influence on enterprise business model is one of the outer - middle - lining the progressive process of traditional enterprise electronic commerce, the process must follow the rules, can receive the good : electronic commerce mode of traditional enterprise organization structure, core competitiveness

Cobb - Douglas production function is a mathematician and economist Cob Douglas, according to the American history 1899-1922 year data, studies the relationship between labor input and capital input and output, a famous production function model. Based on the Cobb - Douglas production function model, the establishment of innovation the study of literature, this paper systematically describes the theoretical basis and derivation of the production function and the Co Bbu Douglas production function model, probably understand the nature and characteristics of the. Co Bbu Douglas production function originated in the production function, so we firstly in the second chapter describes the production function model and the concept of conclusion, then gradually extended to the Cobb Douglas production function, introduced the model and the factors of production and its to the first chapter, second chapter is the theoretical basis of setting Co Bbu Douglas production function in our model, use based on Cobb - Douglas production function model, the establishment of innovation model. Through the analysis of appropriate econometric, exploring the source of economic growth, to study the basic characteristics of China's economic the data of the 15 period of the 1995 to 2009 years, analysis of China's capital and labor inputs for China's social output. Selection on Q, selection of China from 1995 to 2009 of the gross national product of GDP, K and social fixed assets, Y and K are in billion for the unit, L and the number of the employed population in China during this period, with ten thousand men unit. In the actual regression model, the logarithmic form, in order to reduce heteroscedasticity. The results show that: the Cobb - Douglas function to the economic growth of China's explanation is significant, but in our country, the increase of capital contribution to economic growth to increase the contribution to economic growth than labor.

The thesis brings forward the model passing two fork tree that Shan expects first to stock respectively , the by cash bond deduces formula as well as stock and by cash bond combination carry out the value analysing , deducing out the same probability formula and combination's. And then carry out analysis on two fork tree that N expects, any one in thinking that a node of moment becomes two the node at last ramification of n moment from n-1, looks at the person respectively becoming every single-handed Shan scheduled time two fork tree , the rights and interests value calculating out n moment doing not deciding first, makes use of whose two fork tree price to develop process picture and value function with investment of combination and, value debuting n-1 moment, and so on, Can debut front layer of upper value of node from every layer, principle making use of the person and deducing out the call-option value's forward step by step from the day afer tomorrow, the at last may get two branches tree root unitary node value.文章有些长、、望认真看完、、标准人工翻译、、希望可以帮助你、、
