| 中文摘要: |
| 以“宽带中国”战略为准自然实验，基于2009—2021年我国A股上市企业数据，采用渐进双重差分法评估数字基础设施建设对企业绿色创新的影响及其作用机制。研究发现，数字基础设施建设能显著促进企业绿色创新水平的提高，且结论通过了平行趋势检验、安慰剂检验等稳健性检验。异质性分析发现，数字基础设施建设对国有企业、成熟期企业及非重污染企业的绿色创新驱动效应更强。机制检验结果表明，数字基础设施建设主要通过促进企业数字化转型、推动数字金融发展和提高信息披露质量三个渠道助力企业绿色创新。研究结论可为深入推进落实网络强国等国家战略与实现绿色发展提供参考。 |
| 英文摘要: |
| Using the “Broadband China” strategy as a quasi natural experiment， based on data from A share listed companies in China from 2009 to 2021， the impact and mechanism of digital infrastructure construction on corporate green innovation were evaluated using asymptotic double difference method. The research results indicate that the construction of digital infras tructure can significantly promote the improvement of green innovation level in enterprises， and the conclusion has passed robustness tests such as parallel trend test and placebo test. Hetero geneity analysis found that the construction of digital infrastructure has a stronger driving effect on green innovation for state owned enterprises， mature enterprises， and non heavy polluting enterprises. The results of the mechanism verification indicate that the construction of digital infrastructure mainly assists enterprises in green innovation through three channels： promoting digital transformation of enterprises， promoting the development of digital finance， and improving the quality of information disclosure. The research conclusion can provide reference for further promoting the implementation of national strategies such as building a strong cyber nation and achieving green development. |
