Abstract
In 1955, the LDP government introduced “Jizen-Shinsasei” or a decision making procedure in which its government bills have to be approved by the LDP before being submitted to the Diet. When and how did the LDP adjust to the new procedure? This paper quantitatively clarifies, using data of “ ShuginKohou”, that the LDP adjusted to the new procedure in 1959. This is demonstrated by the fact that the government bills have been smoothly approved in the procedure since 1959. This paper also points out two factors which helped the bills to be approved smoothly. First, the Seimu Chosakai, the Policy Affair Research Council （PARC） within the party, started being deeply involved in governmental budget making process in 1958. Second, in the late 1950’s, the LDP’s lawmakers were widely allowed to get into the PARC’s decision making process through greatly in creased the PARC’s apparatns.
