Abstract: Industrialization is the core driving force of county-level urbanization, and the renewal and transformation of industrial parks are crucial starting points to promote the transformation and upgrading of the county economy. At present, China's county industrial development is confronted with dilemmas such as 'decoupling and broken chains, lagging planning, solidified models, and blocked transformation'. Therefore, solving the core issues of county industrial development and achieving revitalization has emerged as an urgent issue in China's pursuit of high-quality development. This paper takes Heyetang Industrial Park in Yiwu City, Zhejiang Province as the research object. It explores the development dilemma of county industry, analyzes its driving mechanisms under the new circumstances, and proposes four planning strategies: Firstly, establish R&D alliances to promote closed-loop development of industrial chains; Secondly, clarify detailed demands and construct long-term growth mechanisms; Thirdly, leverage market advantages to facilitate the transformation of production models; Lastly, guide public demand and achieve low-cost, high-quality development.
