Purpose of this study is to analyze the relationship between Gyeonggi-do's major policy tasks and Gyeonggi-do's Sustainable Development Goals(G-SDGs) using causal loop diagram, and to find policy paths and policy entry points. For this purpose, policy tasks of Gyeonggi-do were linked to the goals and targets of the G-SDGs, and the causal structure of the policies was examined using causal loop diagram. Where link is missed, the National Sustainable Development Goals (K-SDGs) was suggested to complement the missing linkage to improve policy in this area. Study result shows that the Gyeonggi-do policy tasks are closely linked with G-SDGs, forming virtuous cycles. Based on these study results, some suggestions were made for Gyeonggi-do's policy tasks and sustainable development.
