Abstract
Through analysing the above models, the paper draws the following conclusions: the impact of information investment on production performance is U curve; the impact of information investment on production performance depends on introduction, assimilation and re-innovation level of information technology, and then depends on interaction of information technology and production factors and then depends on the scale and quality of capital stock, labour input, industrial technology and information technology; the impact of traditional industry and strategic emerging industry on production performance has obvious differences, but in our country, only chemical raw material, chemical product manufacturing industry, nonferrous metal metallurgy and rolling manufacturing industry, transportation equipment manufacturing industry, production of power, thermal power and supply industry can improve production performance among information investments. Therefore, the theoretical contribution of this chapter is mainly: propose the impact of information investment on production performance appears U-curve and interpret productivity paradox exists in industrial information investment; verify traditional industry and strategic emerging industry of our country promote the difference and direction of information investment and integration of information and industrialization; propose impact mechanism of information investment on production performance is the introduction, assimilation and re- innovation of information technology, the reform of scale and quality of production factors and reform of production paradigm.
