Research and development investment and operational performance of listed small and medium-sized enterprises in China
https://doi.org/10.1080/00036846.2020.1781771
Abstract:This study aims to investigate the impact of research and development (R&D) investment on the operational performance of small and medium-sized enterprises (SMEs) from 2013 to 2017. The findings show that there is a significant negative relation between R&D investment and the operational performance of SMEs in China. This negative effect lasts for three years subsequent to R&D investment. In addition, there is no positive relation between R&D investment and the operational performance of SMEs. The relation between R&D investment and operational performance appears significantly negative for non-state-owned enterprises (non-SOEs) and SMEs with an R&D investment intensity of more than 5%. However, it is non-significant for state-owned SMEs (SOEs) and SMEs with an R&D investment intensity of less than 5%. The two-stage method of the Heckman test and propensity score matching (PSM) are employed in this study to exclude problems of endogeneity, and the results remain robust.
Product-market competition, internal control quality and audit opinions. Evidence from Chinese listed firms
https://doi.org/10.6018/rcsar.369111
Abstract:Based on data on listed firms in the Shanghai and Shenzhen A-share stock markets from 2007 to 2015, this study examines the relations among the quality of internal control, product-market competition and audit opinions. The empirical results reveal that (1) the better the quality of the internal control of listed firms is, the more likely a certified public accountant will be to issue a unmodified opinion; (2) the product-market competition is positively associated with unmodified opinions; (3) the product-market competition weakens the positive relation between the quality of the internal control of listed firms and the likelihood that a unmodified opinion will be issued by a certified public accountant; and (4) the significant impact of product-market competition on the relation between internal control quality and unmodified opinions exists only in non-monopoly industries.
