Abstract:County-level specialty industries that increase rural incomes are key vehicles for advancing rural industry revitalization and ensuring sustained growth in farmers’incomes. Zhanhua District of Binzhou City, Shandong Province, known as“China’s Home of Winter Jujube,”has developed its winter jujube industry for more than 40 years. It has established a specialty fruit-tree industry system characterized by large-scale cultivation, standardized production and integrated value-chain operations. The district currently has approximately 20,000 ha under winter jujube cultivation, with an annual output of approximately 300,000 metric tons. In 2025, the output value of the entire industry chain exceeded RMB 7 billion, generating an average annual per capita income of RMB 16,000 for jujube growers. The winter jujube industry has thus become a pillar industry for increasing local incomes and strengthening the district economy. Taking the Zhanhua winter jujube industry as a case study, this paper systematically analyzes the endogenous resource strengths and external support conditions underlying its development. It identifies major development pathways involving standardization, scaled-up production and operation, integration of the primary, secondary and tertiary industries, green production, risk prevention and management, and legal and regulatory safeguards. On this basis, the paper summarizes a practice-based model for the high-quality development of county-level specialty fruit-tree industries. The experience of Zhanhua may offer useful lessons for other counties in China seeking to develop locally distinctive industries based on local resources, increase rural incomes and advance all-round rural revitalization.
