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.
