Abstract: Taking Shandong Province as an example, seven major vegetable producing provinces including Henan, Hebei, Jiangsu, Hunan, Hubei, Sichuan and Guangdong were selected to calculate and compare the comparative advantages of vegetable production between Shandong Province and these seven provinces from 2003 to 2018, and on this basis, the influencing factors of the comparative advantages of major vegetable producing provinces were analyzed. The study found that the comparative advantage of vegetable production scale in Shandong Province needed to be expanded urgently, the comparative advantage of efficiency continued to increase, and the comprehensive comparative advantage needed to make progress while maintaining stability. The factors influencing the production advantage were quite different. The production advantage was significantly positively related to natural resource conditions and agricultural capital investment, and was significantly negatively related to the level of economic development, market environment and agricultural labor input. Based on this, some suggestions were put forward to ensure the sustainable development of vegetable industry in Shandong Province.
