Abstract: 【Objective】To provide theoretical basis for sustainable and efficient development of yam industry in Guangxi, surveys and analysis on development status and existing problems of Guangxi yam industry were conducted, and countermeasures were put forward.【Method】Based on the field survey investigation and data collection(2018-2020) of main yam producing areas in 14 prefecture-level cities at Guangxi, the development status and main problems of yam industry in Guangxi were analyzed through the perspectives of planting area, major varieties, planting methods, scientific research current situation, selling mode, processing, etc. The suggestion for development were proposed.【Conclusion】At present, Guangxi has become one of the main yam producing areas in China. The planting area was about 18336 ha.The main planting areas were mainly located in Guilin, Hezhou, Guigang, Naning. The main cultivars were Guihuai No.2, Guihuai No.5, Guiahuai No.7 and local varieties. And the planting modes were directional cultivation, making hole cultivation, and machine ditch cultivation. Yam in Guangxi was mainly used for local consumption, exporting and processing.The processing of yam in Guangxi was primary processing, and the main processing products were yamdry slice, yam dry particles, which the processing quantity of yam dry slices in Jintian Town of Guiping was in the front rank of China. Yam industry development momentum was good in Guangxi, because there were three nationalagri cultural products geographical indications registrations and certifications, four pollution-free agricultural products certifications, and three green food certificationsin yam region. But there were also many problems in yam industry. Small processing scale and low added value made it difficult to form a dominant industry. Low brand recognition and insufficient management ability made it lack of influential brands. Insufficient investment in scientific research made research progress slow and further affect the industry-university-research association. These problems seriously restricted the sustainable development of yam industry in Guangxi.【Suggestion】Focus on developing regional competitive producing areas, supporting the development of small enterprises, cultivating and strengthening leading enterprises;implementing the brand strategy, cultivating and strengthening local brands, building Guangxi brands. Attach importance to basic research, promote joint efforts by the industry, universities and research institutes tackle key problems, and then strengthen the integrated development of industrial chains.
