We study the decay width of the inclusive process b --> s g g in the two Higgs doublet model with three level flavor changing neutral currents (model III). We analyse the dependencies of the differential decay width to the s quark energy E_s and model III parameters, charged Higgs mass m_{H^{\pm}} and Yukawa coupling \bar{\xi}_{N,bb}^D. We observe that there exist a considerable enhancement in the decay width for the relevant process. This enhancement can be reduced by choosing C_7^{eff} as negative and increasing the lower bound of m_{H^{\pm}} to the large values, such as 800 GeV . This is an interesting result which gives an idea on the mass m_{H^{\pm}} and sign of C_7^{eff}.
