建筑物区分所有权案件是伴随着我国《物权法》对建筑物区分所有权的确立而产生的。由于该类型案件的诉讼主体广泛,诉讼类型多样,我国理论与实务界对该类型案件的当事人适格问题尚存在争议。本文拟通过分析现行制度的缺陷以及借鉴域外学说和立法例,以民事一体化为进路,提出对我国建筑物区分所有权案件当事人适格制度的完善建议。 Building ownership ownership cases are accompanied by China's “Property Law” arising from the establishment of building ownership. Due to the wide range of litigation cases and litigation types in this type of cases, there is still controversy over the issue of the eligibility of parties involved in this type of cases in China's theory and practice circles. Based on the analysis of the defects of the current system and drawing lessons from extra-territorial theories and legislation, this article intends to take the civil integration as the path, and puts forward some suggestions on how to perfect the system of ownership of buildings in our country.
