加快数字经济发展已成为破解超大城市要素非对称问题、促进农村居民收入阶层跃升的重要路径。基于2025年北京地区4037份农村居民家庭问卷调查数据,采用Probit与SEM模型,实证检验要素非对称视角下数字经济参与对超大城市农村居民收入阶层跃升的影响效应与作用机制。研究结果表明,数字经济参与对超大城市农村居民家庭收入阶层跃升具有显著正向影响。在作用机制上,数字经济参与和信息资源获取、劳动力技能存在互补效应,能缓解信息与劳动力要素的非对称约束,但和资金融通未形成交互影响。在收入结构上,数字经济参与主要通过促进工资性收入增长推动收入阶层跃升,且其与信息资源获取、劳动力技能存在互补效应,与资金融通存在替代效应,而对经营性收入增长的影响不显著。基于研究结论提出政策建议,以期为破解要素非对称约束、推动超大城市农村居民共同富裕提供政策参考。
Accelerating the development of the digital economy has become an important path to solve the problem of element asymmetry in megacities and promote the income class ascension of rural residents. Based on survey data from 4037 rural households in Beijing, this paper uses Probit and SEM models to empirically test the impact and mechanism of digital economy participation on the income class ascension of rural residents in megacities from the perspective of element asymmetry. The research results show that digital economy participation has a significant positive impact on the income class ascension of rural households in megacities. In terms of the mechanism, digital economy participation and information resource acquisition, labor skills have complementary effects, which can effectively alleviate the asymmetry constraints of information and labor factors, but there is no interaction effect with financial resources acquisition. Regarding the income structure, digital economy participation mainly promotes the income class ascension by increasing wage income, among which there is a complementary effect with information resource acquisition and labor skills, and a substitution effect with financial resources acquisition, while its impact on the growth of business income is not significant. Based on the research conclusions, policy suggestions are put forward to provide policy references for solving the problem of element asymmetry and promoting the common prosperity of rural residents in megacities.
