The estimate on meat consumption by M. Nerlove-type dynamic model which parameters are constant over a long term period (1964-1997), was hard to suit. Because the consumption behavior have gradually changed among those period. In this paper, M. Nerlove-type dynamic model was improved so that parameter itself was set as the function of the time variable. The problem of multicollinearity was arisen in this case. Therefore the best model avoided multicollinearity was found by calculating the Pearson correlation coefficient for variables. The results estimated by this model are following. Income and price elasticities of meat were decreasing tendency every year. The habit formation effect increased every year little by little. These are theoretically suitable results, so the change of meat consumption behavior was able to be shown clearly.
