A new method of two‐stage integration in collective variable phase space is proposed for the calculation of the critical part of the partition function of a ferroelectric cluster system. The recursion relations for basic distribution coefficients of consequent block structures are found, taking into consideration dipole‐dipole components of intercluster interaction. A general solution of these relations is obtained. The type of critical behaviour of the system is determind. The phase transition temperature is calculated.
