The purpose of this study is to elucidate the implications of industrial development policy for revitalizing the marginalized industry in the region. In particular, I would like to discuss how to develop the packaging industry that can be categorized as the non - alcoholic and non - alcoholic industries in Daejeon. To do this, we analyzed the industry analysis of the Daejeon and the current status of the packaging industry and analyzed the specificity of the packaging industry based on it. In order to analyze the regional industry, the analysis of industry specialization revealed that the packaging industry in the region is competitive, but it is lacking in terms of industry specialization. Based on this, the implications for fostering and developing the packaging industry, a marginalized industry in Daejeon area, were derived. As a result of the study, it was concluded that Daejeon needs to revitalize the plastics - related industry, which occupies a large portion of the in - house manufacturing industry, in order to revitalize the local economy and to support balanced enterprises and industries. The plastic packaging industry, which occupies a large portion of the manufacturing industry in the Daejeon area, will be developed to develop the industrial structure of the region and make the industrial sector focused on the service industry active in the manufacturing sector. In addition, by providing infrastructure necessary for joint growth of the value chain side, it will be possible to develop a sound industry development plan.
