【摘要】：企业研发活动是技术创新的前提,是企业形成核心竞争力的保证,在激烈的市场竞争中,国外企业将研发列入重要发展战略。在以计算机、互联网为主导的现代社会中,作为我国国民经济主导产业的信息技术产业在研发活动上的表现将直接影响到我国的综合国力。本文通过对生产要素理论、投入产出理论和技术创新理论的论述,分析研发投入的重要性,在充分的理论支持基础上,构建信息技术企业绩效评价体系,对研发投入与绩效的关系进行实证研究。选取沪深两市A股市场信息技术企业为研究样本,以2007年-2010年研发投入相关数据及相关财务指标,选取研发投入金额、研发投入强度、技术人员数量、技术人员投入强度作为衡量企业研发投入的指标,以主营业务利润、主营业务利润率、净资产收益率作为盈利绩效评价指标,以主营业务收入增长率、主营业务利润增长率、净资产增长率作为成长绩效指标,构建多元线性回归模型和修正后的柯布道格拉斯(Cobb-Douglas)生产函数模型,通过两种模型来相互验证结论的可信度。实证研究结果表明：我国上市信息技术企业研发投入不足,多数企业研发投入强度低于国际公认具有竞争力的5%水平,研发投入受企业规模的影响,规模大的企业研发投入力度较高；企业研发投入强度与盈利绩效存在正相关关系,说明加大研发投入力度,有助于增强企业盈利能力；研发投入与成长绩效不存在正相关关系；研发投入对绩效的影响具有滞后性和累积性,滞后两年的影响较大,另外实证结论也从侧面说明我国信息技术行业较国际相比具有巨大的提升空间,应逐步从劳动密集性、资本密集型向技术密集型企业转型。鉴于本文的研究结果,不仅能为我国上市公司,也可为我国非上市公司重视研发活动,提高研发投入强度提供实证依据,对于提高我国信息技术产业的竞争能力有积极意义。
[Abstract]:Enterprise R & D activities are the premise of technological innovation and the guarantee of forming core competitiveness of enterprises. In the fierce market competition, foreign enterprises include R & D as an important development strategy.In a modern society dominated by computers and the Internet, the performance of the information technology industry, which is the leading industry in China's national economy, will directly affect the overall national strength of our country.Empirical research on the relationship between R & D investment and performance.Taking the information technology enterprises of Shanghai and Shenzhen A-share markets as the research samples, taking the relevant data of R & D input and related financial indicators from 2007 to 2010, selecting the R & D investment amount, R & D investment intensity, and the number of technical personnel.The investment intensity of technical personnel is taken as the index to measure the R & D investment of the enterprise, the profit rate of the main business, the profit margin of the main business and the rate of return on net assets are taken as the evaluation index of profit performance, and the growth rate of the main business income and the main business profit growth rate,The growth rate of net assets is taken as the growth performance index. The multivariate linear regression model and the modified Cobb-Douglas production function model are constructed. The two models are used to verify the credibility of the conclusions.The empirical results show that the R & D investment of listed IT enterprises in China is insufficient, and the R & D investment intensity of most enterprises is lower than the internationally recognized competitive level of 5%, and the R & D investment is affected by the scale of the enterprise.There is a positive correlation between R & D investment intensity and profit performance, which indicates that increasing R & D investment is helpful to enhance the profitability of enterprises, R & D investment and growth performance have no positive correlation.The impact of R & D investment on performance is lagging and cumulative, and the impact of two years' lag is greater. In addition, the empirical conclusion also shows that the information technology industry in China has a huge room for improvement compared with the international industry, and should be gradually labor-intensive.Capital-intensive to technology-intensive enterprises.In view of the research results of this paper, not only for our listed companies, but also for our non-listed companies to attach importance to R & D activities, to improve the intensity of R & D investment to provide empirical evidence for improving the competitiveness of the information technology industry in China has a positive significance.
