This is a work on consumer society theory addressing the issue of social stratification.
Literal
Stratification-problem [toward-に対する], consumer-society-theory [possessive-の] work [copula-である].
Academic catalogue-style description. 階層問題 ('stratification problem') and 消費社会論 ('consumer society theory') are heavy kango compounds. The formal copula である closes the sentence as a definitional statement. 著 ('work, publication') is the terse academic shorthand for a published book.
