Study on Influence of Research and Development Investment on Business Performance of Agricultural Listed Companies Based on DEA Model

In this paper,20 major agricultural listed companies in Shenzhen Stock Exchange and Shanghai Stock Exchange were collected as the researched samples,and DEA model was introduced to conduct the survey which took Research and Development( R D) investment,R D investment proportion,and R D personnel proportion as input indexes,and took total asset turnover,weighted average return of equity,operating margin,increase rate of business revenue,and operating profit growth rate as output indexes. The survey results indicated that these agricultural listed companies got a stronger acceleration of business performance due to their R D investment,but with low technical efficiency,which meant their R D investment was not optimized. In the end,some related suggestions to promote the sound development of agricultural listed companies in China were proposed.
