【摘要】：在知识经济时代，企业生产从劳动密集型向资金密集型，尤其是技术密集型转化已经成为国际发展趋势。科学技术以及科技创新对一个企业、一个地区甚至一个国家的长远发展起着至关重要的作用。从某种意义上，谁掌握了新科技，谁就在市场上掌握了主动权。上个世纪末的IT革命向世界诠释了科学技术是第一生产力这个命题，，表明科技创新可以创造经济增长点、推动经济发展。科技创新不仅对高科技产业有着重要的推动和促进作用，对于制造企业同样如此。随着竞争压力的增大，企业越来越意识到研发活动对于自身发展的重要性，越来越多的企业把增强研发投入作为提高竞争力的手段。皖江城市带作为承接产业的新兴经济区，如何利用科技创新提高企业效率，发挥当地的劳动力、自然资源以及区域优势，打造一批成功的高科技制造企业，对于皖江城市带乃至整个安徽省的经济发展具有重要的意义。皖江城市带上市公司的研发投入能否产生积极的产出效果？在多大程度上提高了生产效益？本文就该问题进行实证研究。为研究皖江城市带的研发投入效果，本文以皖江城市带制造业的上市公司作为样本，利用混合回归模型和面板模型研究了研发投入和公司盈利水平的关系，以及研发投入对于公司Q值的影响，得出了研发活动与公司盈利水平、托宾Q值正相关的结论。
