环境保护投入对煤炭企业核心竞争力的影响研究

Research on the Influence of Environmental Protection Investment on Core Competitiveness of Coal Enterprises

文章以2010-2015年我国A股上市煤炭公司为样本,研究环境保护投入对煤炭企业核心竞争力的影响。实证研究结果发现,短期内,环境保护投入对于企业核心竞争力具有负面影响,但长期内却能显著正向影响企业核心竞争力,并对企业核心竞争力有显著的提升作用;规模越大的企业,企业环境保护投入对企业核心竞争力正向影响就越大;股权集中度并未在环保投入对企业核心竞争力的影响方面有显著作用。研究结果肯定了煤炭企业环境保护投入对其核心竞争力的长期影响,同时表明环境保护投入受到企业规模显著的影响。
