\section{Introduction}
Namely, in the case of competition between the PTP and the PSA, where the two ports locate at the closer proximity and the intervention of both governments are critical. The government use the port as the strategic trade policy is questioning. In this similar case, \cite{Minjuetal2011} have
\section{Model}

The port user costs depend on the port capacity, $K$, and volume of total traded good, $X$.
\begin{equation}\label{port user cost}
\tau_m = S_m(\omega_i/K_i)+t,\: i,m=1,2,\: i\neq m
