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。

Abstract:

As a basic industry,mining needs innovative support in key links such as mining,dressing and metallurgy,so as to solve the problem of extensive and inefficient production,boost the construction of green mines and realize the high-quality development of mining.Research and development(R&D) funds are the premise and foundation for enterprises to carry out innovative R&D activities,and the quantity and quality of innovative achievements largely depend on the support of financing system and policy environment.Then,under the control of the “invisible hand” of the market,can the current financing channels of Chinese mining enterprises promote the R&D investment of enterprises?At the same time,under the intervention of the “visible hand” of the government,what role does the government subsidy obtained by mining enterprises play in the relationship between financing channels and R&D investment of enterprises?In this paper,starting from the sources of R&D investment,the listed mining companies in China from 2012 to 2019 were selected as samples,and the feasible generalized least squares method was used for empirical test.It is found that:(1)Both endogenous financing and exogenous financing can significantly promote R&D investment of Chinese mining enterprises.By further dividing the sources of external financing,it is found that equity financing can significantly promote R&D investment of mining enterprises,while debt financing has no significant impact. (2)Government subsidies have a significant positive regulatory effect on the relationship between endogenous financing and R&D investment of mining enterprises.(3)Government subsidies play a role of signal transmission in the relationship between external financing and R&D investment of mining enterprises,that is,government subsidies help mining enterprises to obtain more external financing,thus promoting the establishment of an intermediary role path for R&D investment of enterprises.To some extent,the conclusions of this paper provide reference value for R&D financing of mining enterprises in China,and provide microscopic evidence for the government to formulate relevant subsidy policies,and promote independent innovation of enterprises and the development of capital market.

Key words: endogenous financing, exogenous financing, government subsidies, R&D investment, signal transmission effect, mining listed companies
