An Analysis And Optimization On The Structure Of Research And Development Investment Of Jiangsu Province

After World War II, the science and technology have a rapid development. The science and technology innovation has impact the development of the world economy, and it has been a great impetus and a new profit growth point of the rapid development of the world economy. Research and development (R&D) as the main active of the science and technology innovation has a significant impact on the economic growth and development in every country. The effective R&D investment is important guarantee for the rapid development of science and technology industry, upgrading the industrial structure and sustainable development of regional economy. Government as the principle investor in R&D plays an important guidance function in driving social and enterprise's R&D investment and guiding the direction of the R&D investment. Jiangsu is an economy-prosperous and cultural province. The designed facility is of vital importance for Jiangsu Province to increase our national economy and advance the science and technology. The paper takes R&D investment of Jiangsu Province for example, according to the data from 1998 to 2005, the paper analyses the structure of R&D investment and its effect of Jiangsu Province. Its main contents comprise the following aspects:1. The paper analyzes the structure of R&D investment of Jiangsu Province during the tenth five-year plan on the whole, and identifies the effect and the problems of R&D investment in Jiangsu Province by relevant comparing with other developed provinces;2. Searching and arranging relevant literature on the science and technology investment at home and abroad, on the base of analyzing the input-output factors, we establish the R&D input index evaluation system, and then analyze the R&D fund input structure of Jiangsu Province during the tenth five-year plan;3. Statistics the data of R&D investment in Jiangsu Province from 1998 to 2005, the paper put forward the contribution ratio of basic,applied and developing research to output according to the grey correlation of the grey theory; By forecasting the structural and the total inputs of R&D by means of the improved grey interval forecast model, we establish the constraint condition and the multiple target linear programming models, then solve the equation in order to design the optimal structure scheme of the R&D investment in Jiangsu Province during the tenth five-year plan. 4. According to practical situation of Jiangsu Province, the paper gives some advice to rationalize the R&D investment structure and increase the benefits of the R&D investment of Jiangsu Province.
