The purpose of the research is to analyze positively actual conditions that the councilor use the legislative information, to reveal the factors witch influences on the legislative information use, and to seek the way of improving the legislative information use. The datas used in this research are council records of Kyong-Sang-Book-Doo(1995: 97th, 98th, 99th, 100th), questionnaire, and councilor`s memorandums. The analysis was made by simple statistics which verified the relationship between variables. There was a wide difference between the levels where the council used the legislative information. The actual state is basically due to legislative orientation or duty recognition of councilor are more active in their region than in the council and use not so much the objective and scientific information of policy as the political information related to the ideological, moral, and ethical. When we group the councilor`s type of law-making into two classes, that is, council-oriented and region-oriented, the former is relatively using policy information much more than the latter and is on the higher level in using legislative information than the latter. The way to improve the legislative information use is to convert the legislation orientations of the councilor. To convert the legislation orientation is impossible without the overall approach of councilor`s activities. In orther Words, we should try to convert the political environment of the council beyond the structural approach of council until now. One of the alternatives, that is, the way of converting the constituency to the major constituency requires active examination.
