摘要:
选取2012~2019年中国矿业上市公司为研究样本,采用可行广义最小二乘法进行实证分析,考察了融资渠道对矿业企业研发投入的影响,并检验了政府补助的调节效应与信号传递效应。研究发现:(1)内、外源融资均能显著促进中国矿业企业研发投入,对外源融资渠道做进一步划分发现,股权融资对矿业企业研发投入有显著促进效应,而债权融资则不具有显著影响;(2)政府补助对矿业企业内源融资与研发投入之间的关系具有显著的正向调节效应;(3)政府补助对矿业企业外源融资与研发投入之间的关系具有信号传递效应,即政府补助有助于矿业企业获取更多的外源融资,进而促进企业研发投入的中介作用路径成立。研究结论为我国矿业企业研发融资提供了参考,同时为政府制定相关补贴政策、促进企业自主创新及推动资本市场发展提供了微观证据。
