Space-borne gravitational wave detectors like TianQin are expected to detectGW signals emitted by the mergers of massive black hole binaries. Luminositydistance information can be obtained from GW observations, and one can performcosmological inference if redshift information can also be extracted, whichwould be straightforward if an electromagnetic counterpart exists. In thispaper, we concentrate on the conservative scenario where the EM counterpartsare not available, and comprehensively study if cosmological parameters can beinferred through a statistical approach, utilizing the non-uniform distributionof galaxies as well as the black hole mass-host galaxy bulge luminosityrelationship. By adopting different massive black hole binary merger models,and assuming different detector configurations, we conclude that thestatistical inference of cosmological parameters is indeed possible. TianQin isexpected to constrain the Hubble constant to a relative error of about 4%-7%,depending on the underlying model. The multidetector network of TianQin andLISA can significantly improve the precision of cosmological parameters. In themost favorable model, it is possible to achieve a level of 1.7% with a networkof TianQin and LISA. We find that without EM counterparts, constraints on allother parameters need a larger number of events or more precise skylocalization of GW sources, which can be achieved by the multidetector networkor under a favorable model for massive black hole mergers. However, in theoptimistic case, where EM counterparts are available, one can obtain usefulconstraints on all cosmological parameters in the Lambda-CDM cosmology,regardless of the population model. Moreover, we can also constrain theequation of state of the dark energy without the EM counterparts, and it iseven possible to study the evolution of EoS of the DE when the EM counterpartsare observed.
