【摘要】 数字化转型的创新驱动效应逐渐成为制造企业高质量发展的突破点，同群企业间数字化转型的相互学习与模仿对企业双元创新具有重要影响。以2017—2022年中国沪深A股上市公司为研究样本，研究数字化转型行业、地区同群效应的存在性及成因，探究数字化转型同群效应对制造企业双元创新的影响效果与作用机制，考察市场竞争强度、环境不确定性水平对数字化转型同群效应与制造企业双元创新关系的调节效应，检验不同技术属性、产权性质与生命周期特征下数字化转型同群效应对企业双元创新影响的异质性。研究发现：制造企业数字化转型存在显著的行业同群效应与地区同群效应，且二者通过不同路径显著促进制造企业双元创新。其中，数字化转型行业同群效应能够显著降低企业业绩期望差距，数字化转型地区同群效应有助于提升企业服务化水平。进一步研究发现，市场竞争强度、环境不确定性水平分别在数字化转型行业同群效应、地区同群效应与制造企业双元创新关系存在倒“U”型调节作用和正向调节作用。异质性分析表明，数字化转型同群效应对非国有企业、成熟期企业双元创新的促进作用显著强于国有企业、成长期与衰退期企业。更多还原

【Abstract】 The innovation-driven effect of digital transformation has gradually become a breakthrough point for the high-quality development of manufacturing enterprises, and the mutual learning and imitation of digital transformation among cohort enterprises has an important impact on enterprise dual innovation. Taking Chinese A-share listed companies in Shanghai and Shenzhen from 2017 to 2022 as research samples, we explore the existence and causes of digital transformation industry and regional cohort effect, investigate the effect and mechanism of digital transformation cohort effect on dual innovation of manufacturing enterprises, examine the moderating effect of market competition intensity and environmental uncertainty level on the relationship between digital transformation cohort effect and dual innovation of manufacturing enterprises, and test the effect of digital transformation cohort effect and dual innovation of manufacturing enterprises under different The study examines the moderating effect of market competition intensity and environmental uncertainty level on the relationship between digital transformation cohort effect and dual innovation of manufacturing enterprises, and tests the heterogeneity of the impact of digital transformation cohort effect on dual innovation of enterprises under different technological attributes, property rights and life cycle characteristics. The study finds that there are significant industry cohort effects and regional cohort effects of digital transformation in manufacturing enterprises, and both of them significantly promote dual innovation in manufacturing enterprises through different paths, and this conclusion still holds after the robustness test and endogeneity test. Among them, the digital transformation industry cohort effect can significantly reduce the performance expectation gap of enterprises, and the digital transformation regional cohort effect helps to improve the level of enterprise servitising. It is further found that market competition intensity and environmental uncertainty level have an inverted U-shaped moderating effect and a positive moderating effect in the relationship between digital transformation industry cohort effect, regional cohort effect and dual innovation of manufacturing enterprises, respectively. Further heterogeneity tests show that the effect of digital transformation cohort effect on dual innovation is more significant for non-state-owned enterprises, and the promotion effect of digital transformation cohort effect on dual innovation is significantly stronger for non-state-owned enterprises and mature-phase enterprises than for state-owned enterprises, and growth-phase and decline-phase enterprises. The findings of the study help to understand the strategic value of digital transformation, clarify the differences in the paths of digital transformation cohort effects on dual innovation in manufacturing enterprises, and provide theoretical basis and practical reference for exerting the multiplier effect of digital transformation cohort effects, promoting the high-quality development of manufacturing enterprises, and constructing an innovative country.更多还原
