The set of 9yearoldheight data of 24 provenances of masson pine (Pinus massoniana Lamb,) from 9 regional trial locations with good growth was used to establish height response function for each provenance grown at different latitudes.

This paper analyses the long-term effectiveness impacted by the carryover of selling effort,and improves the response function of the control units used in the size deciding.

The estimation of the reaction function of firms, the equilibrium solution and the equilibrium time are also provided.

By analyzing the profit distributing of the managers and accounting units with probability and optimization theories,reaction function of managers and accounting units is present,and the math model of the accounting supervision is established.

By introduction of rivals reaction function the strategic decisions of mergered firms are discussed,from which some interesting conclusions are drawn.
