以2012—2021年煤炭行业26家上市公司数据为研究样本,探讨了煤炭上市公司安全投入与短期企业竞争力和长期企业竞争力的关系,并研究技术创新在二者关系中的调节效应。结果表明:煤炭企业安全投入对短期(当期)企业竞争力存在负向影响,对长期(滞后二期、三期)企业竞争力存在正向影响;技术创新在当期会对安全投入与企业竞争力的负向关系起到削弱作用,但在长期,技术创新对二者关系不存在显著的调节作用。

Based on the data of 26 listed companies in coal industry from 2012 to 2021, this paper discusses the relationship betweensafety investment of listed companies in coal industry and short-term enterprise competitiveness and long-term enterprise competitiveness,and investigates the moderating effect of technological innovation in the relationship between them. The results show that the safetyinvestment of coal enterprises has a negative impact on the short-term (current) enterprise competitiveness, and a positive impact on thelong-term (two lagging periods and three lagging periods) enterprise competitiveness; it is also found that technological innovation willweaken the negative relationship between safety investment and enterprise competitiveness in the current period, but technologicalinnovation has no significant moderating effect on the relationship between them in the long run.
