上市公司过高的股利发放率会增加对外部融资的依赖,从而增大融资成本,但是由于创新重要性的突显,上市公司对RD投入的不断加大降低了股利政策对融资约束的影响。利用2012—2014年我国A股上市公司为样本,实证研究基于RD投入调节作用下公司股利政策对融资约束的影响,得到结论:(1)加入RD投入调节前,上市公司股利政策对融资约束有负向影响;(2)加入RD投入调节后,上市公司股利政策对融资约束有正向影响。最后提出上市公司创新驱动发展战略建议。 相似文献

山茱萸属应予重新确认 总被引:1,自引:0,他引:1
The genus Macrocarpium has been accepted only by a few scholars since
its separation from Cornus L. by T. Nakai in 1909. Bentham, Hooker, Hutchinson and
the others consider that the ovary of Macrocarpium is 2-celled and the genus should be
placed back into Cornus. We have discovered that are generally I-celled. In addition,
Macrocarpium is different from Cornus in basic chromosome number (X), flowering
physiological character, inflorescence type and involucral scale. Thus the genus Ma-crocarpium (Spach) Nakai should be reaffirmed. 相似文献
