The Comparative Research Of Knowledge Capital Input And Output

In the modern age, human being society has entered into an important period in which technological innovation continually emerges. Knowledge is increasingly prominent in the economic and social development. From the standpoint of the global economy, the world is at the eve of the third science and technology revolution and the new knowledge economy is springing up. In this background, carrying on the research about knowledge capital input and output will have great value in theory and realistic significance.Based on Cobb-Douglas production function, this paper examines the input-output effect of each knowledge capital and compares the effects of different regions and industries by using China’s industrial enterprise panel data from1997to2010. The research finds that, the inputs of technology development, technology reform, national technology introduction and digestion have positive impacts on the productivity, but foreign technology import investment cannot raise the productivity.The results also show that, the knowledge capital inputs in different regions have different impacts on Total Factors Productivity. In the Eastern region, technology development input, foreign and national technology introduction inputs can improve productivity effectively, but the inputs of technology reform and digestion do not. In the Central region, the technology development, technology reform and digestion inputs have significant positive impacts on the productivity. In the Western region, technology development and technology reform can promote the increase of productivity. In addition, the input-output effects of knowledge capital in the manufacturing industry have obvious industrial differences which depend on industrial technology opportunities. The productivity of high-tech industries is influenced by technology development input and national technology introduction investment. For the low technology industries, the technology development, technology reform and national technology import can promote the improvement of productivity.
