摘要 基于成本黏性视角,以2013—2020年沪深A股上市公司为研究对象,研究了数字金融对企业研发成本黏性的影响机制及效应。研究结果表明:数字金融抑制了企业研发成本黏性,其中数字金融对东部企业和非国有企业研发成本黏性的抑制作用更加明显,在经过内生性检验、替换核心变量、联合固定效应等一系列稳健性检验后这一结论仍然成立。机制检验发现:资本配置效率和信息透明度在数字金融对企业研发成本黏性的影响中具有部分中介效应,数字金融通过提升资本配置效率和提高会计信息透明度抑制了企业研发成本黏性。效率检验发现:企业研发成本黏性对企业创新质量具有显著的抑制作用,而对企业创新数量影响不明显,数字金融有助于降低企业研发成本黏性,从而提升企业创新质量。本文的研究结论深化了成本视角下对企业研发创新的理解,并对推动数字金融赋能企业创新降成本和促进企业高质量发展具有现实意义。

Abstract: Based on the perspective of cost stickiness, this paper studies the influence mechanism and effect of digital finance on R&D cost stickiness of Shanghai and Shenzhen A-share listed companies from 2013 to 2020. The results show that digital finance suppresses the stickiness of R&D costs of enterprises, and the inhibitory effect of digital finance on R&D cost stickiness of eastern enterprises and non-state-owned enterprises is more obvious. This conclusion is still valid after a series of robustness tests, such as endogenous test, replacement of core variables, joint fixed effect and so on. Mechanism test shows that capital allocation efficiency and information transparency have some intermediary effects in the impact of digital finance on R&D cost stickiness. Digital finance suppresses R&D cost stickiness by improving capital allocation efficiency and accounting information transparency. The efficiency test finds that the stickiness of R&D cost has a significant inhibitory effect on the quality of enterprise innovation, while the positive effect on the quantity of enterprise innovation is not obvious. The digital finance can help reduce the stickiness of corporate R&D costs and improve the quality of corporate innovation. The conclusion of this paper deepens the understanding of enterprise R&D innovation from the perspective of cost behavior, and has important practical significance for promoting digital financial innovation to “ reduce cost ” and promote high-quality development of enterprises.
