Abstract: The county‑level economy is an important guarantee for rural revitalization, and the development of industries is the “pillar” of county‑level economic prosperity. After data analysis, the overall strength of the county economy in Jiangsu is now stronger, the income of rural residents has grown steadily, the industrial structure has been optimized, and the urban-rural income gap has been narrowing. Due to factors such as excessive division of labor in industries, incomplete rural circulation system, information asymmetry, and imperfect institutional mechanisms, Jiangsu currently does not match the high‑quality development requirements of county‑level prosperous industries in terms of industrial development sustainability, inter industry cooperation, county‑level commercial system, industrial factor resource flow, rural indigenous people's quality, and new farmer training. Through a comparison of the development models of county‑level prosperous industries between Jiangsu and Zhejiang, the paper proposes some suggestions for the high‑quality development of industries that enrich the people in Jiangsu counties, namely, building a new concept of natural economy and nurturing an ecosystem of strong main industries, active sideline industries and prosperous diversified industries, putting into effect rural e‑commerce reward and subsidy policies to enhance the sales capacity of agricultural brands, standardizing the management of rural collective assets and improving farmers' income and subject status, paying high attention to the vulnerable groups in rural areas and opening up a new track of enriching and benefiting the people, breaking through and simultaneously promoting a unified market, promoting the free flow of factors and nurturing ecology.

摘要： 县域经济是乡村振兴的重要保证，而产业的发展是县域经济繁荣的“顶梁柱”。经数据分析，目前江苏县域经济总体实力较强、农村居民收入增长稳定、产业结构不断优化、城乡收入差距不断缩小。但受产业过度分工、农村流通体系不健全、信息不对称、机制体制不完善等因素制约，江苏在产业发展可持续性、产业间协作、县域商业体系、产业要素资源流动、农村原住民素质及新农人培养等方面与县域富民产业的高质量发展要求不匹配，通过江苏与浙江县域富民产业发展模式的对比，提出江苏县域富民产业高质量发展的建议，即构建新自然经济理念，孕育主业强副业活百业旺的生态圈；实施农村电商奖补政策，提升农业品牌销售能力；规范管理乡村集体资产，提高农民收入及主体地位；高度关注农村弱势群体，开辟安民富民慧民新赛道；立破并举统一市场，促进要素自由流动育生态。
