Is there a finite vs. nonfinite distinction in Chinese?

Some special devices are designed to test the existence of the finiteness of a Chinese clause, though Chinese evidently fails to meet the general conditions on finiteness. These tests include the occurrence of aspectual markers and modals as A UX in finite but not in nonfinite clauses, the obligatory nullness of the subject of the nonfinite clause (Huang 1988 [1982],(1) 1984, 1987, 1989), the cooccurrence constraint, and the licensing of negative polarity items (Y.-H. A. Li 1985, 1990), as well as C-C. Tang's (1990) criteria, which are not much discussed in the literature. In this paper ive make a careful study of all these criteria specially, devised for Chinese and find that none of them can make a valid distinction between finiteness and nonfiniteness. Since, as far as ve know, there is no independent evidence to support such a distinction, ive conclude that it in fact does not exist in Chinese.
