| Science and technology is playing a more and more important role in today's world. The power of science and technology is a decisive factor for a nation's economic growth and international competition ability. High-tech industries are the combination of top technologies and economic power, which is also the frontier to turn science and technology into real productivity. Government plays a key role in the development of the high-tech industries. This paper carries out a study on government's intervention of the high-tech industries. Firstly, the paper illustrates why the government's intervention is necessary. Secondly, the paper expounds the common disciplines that the government has in intervening in the development of High-tech industries. Finally, after summarize both domestic and foreign experience, the paper gives some policy suggestion to China's governments of different levels. There are four chapters in this paper except for the preface. Chapter 1 High-tech Industries and Economic Development This chapter will firstly clarify relative conceptions, and then it will review economists'discussion about the relation between technology and economic development. High-tech industries are the general concept of enterprise groups or enterprise corporations founded on the basis of high-tech research, development, promotion and utilization. Compared with the traditional industries, high-tech industries have following characteristics:(1) high intensity of knowledge and technology;(2) large investment in both of research fund and fixed assets;(3) high venture and great uncertainty in both the research and market promotion of High-tech products;(4) high potential profit, which means that the organic constitution is relatively high and venerable to form monopoly ;(5) be facile to inosculate with correlative industries. The density of R&D expenditure and the density of professional technical experts are common-used indexes in the quantitative analysis of high-tech industries. Economists have always attached great importance to the effects that technology innovation has on economic growth. Classical economists pointed out the contribution of specialized knowledge and technology in economic growth with elegant phrases. They regarded technology and science as an important productive force. Schumpeter even clearly identified economic growth as innovation itself in his innovation theory. Modern economists proved predecessors'ideas with precise mathematic models. In a series modern economic growth models, technology has always firmly held its position as an essential production factor. Chapter 2 The Necessity of Government's Intervention in High-tech Industries This chapter firstly indicates that market failures will appear in the high-tech industries'developing progress due to its own characteristics. And Government's intervention is helpful to eliminate those market failures. In order to achieve this goal, government must learn to how to smoothly deal with the relationship between market and private enterprises. There are three clues to help us comprehend why high-tech industries bring on market failures. Firstly, high-tech industry not only needs large investment but also have great risks and uncertain investment reward.Therefore, private investors don't have enough profit motivation to invest in those fields, which also cause the unbalanced investment between different industries. Secondly, most products of high-tech industries have qualities of quasi-public goods. Their supply is always in shortage when market system works without any intervention. Thirdly, a lot of high-tech products have external economy, which means there exists knowledge spillover and technology diffusion effects in those products. When those products are consumed, in spite of their producers'reluctance, knowledge and technology embedded in those products will spill over and diffuse into the whole society without any return. Such a foreground depresses the producers'enthusiasm to supply enough goods. Due to the above three causes, it is necessary for government to intervene in high-tech industries'development. Government's intervention will not only have to fill the gap between private proceeds and society ones, but also to encourage efficient supply of high-tech product. The intervention of government doesn't mean it will replace the market mechanism, but means that it will correct and make up market failures. Government's intervention and adjustment should be based on the premise that enterprises are the main entities in the market and it should not replace the enterprises to conduct specific production. Government should achieve its goal by guidance policies but not compulsive plans. In one hand, government can utilize macro-control and take a series measures including education measures, procurement measures, taxation measures and capital market regulation to establish a good environment of continuous innovation that will benefit high-tech industries'development. On the other hand, government should endeavor to cultivate an excellent market mechanism by refraining enterprisesfrom abusing their monopoly power, maintaining fair competition order, properly compensating the technology spillover effects and high stakes in technology development. Chapter 3 Foreign Governments'Support Policies of High-tech Industries This chapter studies on the foreign experience. In recent years, more and more countries observe that high-tech industries take a very important role in the national economic development. In order to support the development of high-tech industries, many countries'governments make a series of industry measures including taxation measures, procurement measures, credit measures and allowance measures. This chapter introduces the development course of high-tech industries in U.S.A., Japan and South Korea in details. U.S.A and Japan hold top two positions in the development level of high-tech industries in the world. South Korea is successful to realize an economic take-off by its high-tech industries'rapid growth. China can learn a lot from three countries'experience in government's supporting policies. Chapter 4 The Development of China's High-tech Industries and the Supporting Policies of China's Government This chapter studies on the actuality of China's high-tech industries and brings forward some suggestions on how our government can successfully exert its role in the development of high-tech industries. Since 1985, China's high-tech industries develop rapidly and have acquired a lot of achievements. There also exist some problems that cannot be ignored. Those problems include: weak links between research and product;...
