| Summary: | 碩士 === 國立彰化師範大學 === 商業教育學系 === 86 === In this paper, stock price, dividend, earning per
share and shareholders* equity return rate are used to
build the simultaneous financial model of industry. Two
stage least squares and three stage least squares are
applied on the estimation of simultaneous financial
model. The optimal control theory will be applied to build
the optimal financial control model, and the optimal control
solution will serve as a guide for business managers to make
financial decisions. Two major points are found in
this research: 1.Three stage least squares is better than
two stage least squares in R-square and the
significance of variables. Therefore, in this paper,
the simultaneous model estimated by three stage least
squares will be used to build the optimal control model.
2.Depending on the optimal control model, we suggest that
Taiwan Liton electronic co.ltd can enhance it*s liabilities-
assets ratio. It should set the turnover of fixed assets to
2.96, and the net profit rate to 1.41%.
Keywords: simultaneous model, optimal control
