Empirical Analysis On The Input-output Effect Of R&D And Its Effect On The Employment In China's Manufacturing Industries

Manufacturing is the very important pillar industry which has occupied a pivotal position in Chinese national economy.With Chinese economy merging into the world economy since opening up and reform,Chinese manufacturing develops rapidly with scale and international competitiveness rising continuously.However,in the development of the manufacturing sector it also exposed a lot of problems,the manufacturing technology content of our country are low,the core technology in many industries mainly dependent on overseas import;the dominating development pattern of manufacturing belong to extensive mode.Competitive advantages mainly from the low-cost labor and production factors.That our country relies mainly on the cost of factors of production to obtain competitive advantages of production is very difficult to maintain our country's long-term healthy development of the manufacturing sector,so increasing the capacity of technological innovation of the manufacturing sector and transforming the mode of production has becoming the key factor to ensure the rapid development of manufacturing sector.The critic idea of technological innovation is R＆D,and the innovation which can achieve long-term development of the manufacturing sector has become a significant international consensus.The creativity consciousness of manufacturing enterprises in our country is continuously strengthened in recent years;at the same time,the industrial enterprises' R＆D output has become the mainstay of our country's manufacturing sector.In order to study the sector R＆D developments of various sectors of China's manufacturing,this paper refer the data of China's large and medium-sized manufactural enterprises in various sectors from "Statistical Yearbook of Science and Technology of China"(1994-2008).The methods we used include panel data,VAR,impulse response function and so on.We empirical researched effect of R＆D investment as well as the correlation between technological progress of the manufacturing sector and employment.Through empirical analysis we found that in input-output effects of China's manufacturing industry,capital-intensive industries' R＆D input-output effects is most obvious,followed by technology-intensive industries,labor-intensive industries is the smallest.The quantity of R＆D investment in technology-intensive industries is largest but the contribution is not as expectance in output.In addition,the improvement of manufacturing technology caused by R＆D can increase the employment in short time but is going to regain balance in the long run.
