Abstract: As an advanced form of productivity driven by innovation and typified by high technology, high efficiency, and superior quality, new quality productivity plays a vital and practical role in facilitating the high-quality development of Jiangxi’s tea industry. Based on the theoretical framework of new quality productivity, this study analyzes its significance in the tea industry. Combined with the realistic scenario of the tea industry in Jiangxi Province, this paper discusses the problems faced by the high-quality development of tea industry in the province, and puts forward the specific practical approach to promote the high-quality development of tea industry. The tea industry in Jiangxi Province has maintained steady growth in terms of area and yield, tea germplasm resources are relatively abundant, and brand influence is gradually increasing. However, small-scale industries still have low output per unit area. The tea garden infrastructure is weak with limited processing capacity of tea products, and the number of leading tea enterprises is not large. There is a lack of “chain” enterprises to drive the efficient and coordinated development of upstream and downstream market players, and the overall brand value is not high with marginal market competitiveness. The number of agricultural science and technology personnel is insufficient, and the conversion rate of research and development investment and technological achievements is low. Moreover, the excavation of tea culture and external displays are insufficient. Therefore, scientific and technological innovation should be emphasized for transformation and upgradation of the tea industry. Besides, it is also suggested to accelerate the provenance innovation, strengthen the development and utilization of tea germplasm resources, promote industrial integration and development of the tea industry, strengthen the brand building, enhance the competitiveness of Jiangxi tea market, build a tea industry talent highland, deepen the charm of Ganpo tea, create a characteristic Jiangxi tea culture, and promote tea education and other measures. These measures can significantly improve the quality of Jiangxi tea, enhance market competitiveness, and enrich the connotations and development of the tea industry. The Jiangxi tea industry will achieve high-quality development under the guidance of the new quality productivity.
