Research On Influence Of Information Industry On Development Of National Economy

After 1990's, since information technique (IT) has been developing apace, the study on information industry has become an international hot subject. The scholars who came from management, economy, science and technology, information etc. have been attracted by the research; they study the information industry's development regulation, the influences upon economy and society, development strategy, development model etc. from different point of view, In various studies, few researches which study the influences of information industry to economic structure and employment can not be found easily; the quantitative study of the influence of information industry to economic growth fasten their attention on traditional regression analysis; the studies of evaluation of information industry development have built up many systems, the substantial quantitative study of evaluation is absent. The paper's study aims at providing a theoretic support to develop our countries' information industry.Firstly, the paper builds up system framework of research on influence of information industry on national economy, and analyses the current situation of Chinese information industry. The foreign experiences of the development of overseas information industry are studied in the paper. The paper analyses the regional model of information industry of our country. The advanced research of the paper which studies the development of information industry is the combination of theory and practice.Secondly, the paper quantitatively studies the influence of information industry on economic growth using the cointegration test in time series econometric analysis, positively researches the development of information industry is the Granger cause of economic growth, when the logarithm of information industry increases 1%, the logarithm of GDP increases 0.4666%; the paper proves that the development of information industry has the long-term and stable contribution to economic growth by impulse response. The paper founds the model of information industries' contribution to economic growth, calculates the marginal contributing ratio of information industry and the three major industries to economic growth using multiple linear regression analysis, the ratio of information industry is 4.52%, the ratio of the second mdustry is 45.79%, these ratios indicate that our country is still in the industrialization society, information industries' contribution to economic growth has occurred, there is a long way to the informatization society.Thirdly, the paper quantitatively studies the influence of information industry to employment for the first time. The paper positively researches that there is a cointegration relation between the development of information industry and employment, the contribution of information industry to the total employment is continual, stable and positive. Studying the cointegration relation of the ratio of information industry to GDP and the ratio of third industries' employment to total employment, the paper positively studies that the development of information industry can present contribution to optimize employment structure, there is a cointegration relation between the development of information industry and employment, the contribution of information industry to the total employment is continual, stable and positive. These studies make up the blank in former researches and are of great practical value.Fourthly, the paper designs an evaluation model of Heilongjiang's information industry, builds homologous evaluation system, obtains the related statistical data and evaluates each province's information industry for the first time, confirms that Heilongjiang's information industry development force ranks the 16^th in our country.Finally, the paper presents countermeasures and suggestion to develop our countries' information industry. The model analysis and quantitative studies can give the direction which develop our countries' information industry fastly and continually.
