In recent years, the rapid development of Marine economy in Guangdong Province has become one of the main pillar industries. Therefore, it is particularly important to study the sustainable development of Marine economy in Guangdong Province. This paper is based on the 2030 Sustainable Development Goals (SDGs) proposed by the United Nations Commission on Sustainable Development. The vulnerability index system of the Marine economic system of Guangdong Province was constructed from four aspects: coercion (P), sensitivity (S), elasticity (E) and adaptability (A). TOPSIS model and obstacle degree model were used to analyze the vulnerability and obstacle factors of the Marine economic system of Guangdong Province from 2007 to 2018.The results show that compared with 2014, the transformation of Marine economy optimization in Guangdong Province is the most obvious in 2015. In the criterion layer, sensitivity proximity showed an upward trend. Sensitivity had the greatest impact on the vulnerability of the system from 2014 to 2018, elasticity had the greatest impact on the vulnerability of the system in 2011, and stress had the greatest impact on the vulnerability of the system in the remaining years. The order of obstacle degree in each criterion layer from high to low is: stress, elasticity, adaptability and sensitivity. The main obstacle factors in the index layer are the import and export value of goods in the coastal area according to the location of the business unit, and the area of Marine nature reserves.
