分析我国大中型工业企业各项科技活动支出的绝对量及变化、支出强度及变化,构建基于柯布-道格拉斯生产函数的计量模型,运用2005—2011年32个工业行业的面板数据研究不同科技活动对产出的影响,主要结论为,(1)各项科技活动的支出均呈增长态势,其中 R&D 内部支出增速最快;除了 R&D 内部支出的强度在增加外,其余五项的支出强度在减弱。(2)R&D 内部支出、引进国外技术经费支出、消化吸收经费支出对工业销售产值有显著正影响,R&D 内部支出的产出弹性明显高于引进技术经费支出和消化吸收经费支出的产出弹性;R&D 外部支出对工业销售产值没有显著影响;购买国内技术支出对工业销售产值存在显著影响,但弹性系数为负值,存在一定程度的负效应。并分析原因给出相应建议。
分析我國大中型工業企業各項科技活動支齣的絕對量及變化、支齣彊度及變化,構建基于柯佈-道格拉斯生產函數的計量模型,運用2005—2011年32箇工業行業的麵闆數據研究不同科技活動對產齣的影響,主要結論為,(1)各項科技活動的支齣均呈增長態勢,其中 R&D 內部支齣增速最快;除瞭 R&D 內部支齣的彊度在增加外,其餘五項的支齣彊度在減弱。(2)R&D 內部支齣、引進國外技術經費支齣、消化吸收經費支齣對工業銷售產值有顯著正影響,R&D 內部支齣的產齣彈性明顯高于引進技術經費支齣和消化吸收經費支齣的產齣彈性;R&D 外部支齣對工業銷售產值沒有顯著影響;購買國內技術支齣對工業銷售產值存在顯著影響,但彈性繫數為負值,存在一定程度的負效應。併分析原因給齣相應建議。

The paper discusses the characteristics of expenditure on S&T activities,expenditure -intensity and their chan-ges in Chinese large and medium -sized industrial enterprises,sets up an econometric model based on Cobb -Douglas pro-duction function and then analyzes the effect of various S&T activities on output using the panel data of 32 industries from 2005 to 2011.The main empirical findings are as follows:the expenditure of various S&T activities is on the increase and the growth rate of intramural expenditure on R&D is the highest;the expenditure -intensity of intramural expenditure on R&D is increasing and the expenditure -intensity of the other S&T activities is decreasing;intramural expenditure on R&D,expenditure for acquisition of foreign technology and expenditure for assimilation of technology have a significant pos-itive effect on sales value of industry;the output elasticity coefficient of intramural expenditure on R&D is significantly lar-ger than the output elasticity coefficient of expenditure for acquisition of foreign technology and expenditure for assimilation of technology;external expenditure on R&D has no significant effect on sales value of industry;the output elasticity coeffi-cient of expenditure for purchase of domestic technology is negative and expenditure for purchase of domestic technology has negative effect on sales value of industry.Finally we find out the causes and put forward some recommendations.
