PurposeChallenges from the urban–rural disparity immensely burden the world's progress fulfilling Sustainable Development Goals and the goals' central promise, particularly for developing countries experiencing rapid structural change and urbanization. A knowledge gap lies between the epistemology of urban–rural disparity and the practice of integrated urban-rural development. This paper aims to provide a new approach to bridge the knowledge gap based on the recent Chinese experience.Design/methodology/approachThis qualitative research reviewed major economic and multidisciplinary studies regarding urban-rural development and the growth-equality tradeoff. Chinese experience is employed to showcase concrete challenges from the urban–rural disparity and how the proposed approach works for urban-rural integration.FindingsTheoretical and practical approaches with urban bias largely fail to counter the challenges. Building on China's recent practice probing beyond urban bias, IFPRI (2019) proposes the term rurbanomics with a highlight of equalized urban-rural economic partnership, whereafter Zhou and Chen (2021) enrich the term into a conceptual framework. This paper further improves rurbanomics as a new viable approach to integrated urban-rural development under the overarching goal of common prosperity. The approach prioritizes driving forces in the economic, demographic, eco-environmental, social institutional and technological aspects for the policy community to leverage. Long-term mechanisms are decerned to link urban-rural integration to common prosperity.Practical implicationsChina has leveraged ingredients of the rurbanomics approach in the political deployment to integrated urban-rural development. However, the application of this approach is yet to be adapted with local heterogeneities and live up to application's potential. Long-term mechanisms recommended by the rurbanomics approach will need to be carried out. Future improvements will need substantial theoretical extension and micro-level empirical studies.Originality/valueThis paper streamlines the epistemological shreds regarding pursuits, challenges, global experiences and theoretical approaches of urban-rural development. The paper also develops rurbanomics to navigate urban-rural integration, Sustainable Development Goals and common prosperity. By decerning long-term mechanisms in the Chinese case accordingly, this paper provides clues for other economies to employ the new approach.
