With the expansion of the IP industry chain

film and television adaptation has become a vital component of China's cultural market. Conflicts between the adaptation right and the right of integrity now figure prominently in judicial practice

producing inconsistent standards and confusion in the application of the law. Under the Copyright Law of the People's Republic of China

the right of integrity is classified as a moral right

while the adaptation right belongs to the author's economic rights. Their divergent legal nature and protective aims have blurred the line between "reasonable adaptation" and "infringing distortion." Taking the

Nine-Layer Demon Tower

case as a point of departure

this paper argues that courts have too often overlooked the need to distinguish the legal nature of an adaptive work. "Substantial similarity" should serve as the logical starting point for infringement analysis: only where an adaptive work is substantially similar to the original in its protected expression may the right of integrity be triggered. On the standard of liability

the paper proposes replacing traditional criteria with a "disruption of work identity" model

integrating the objective degree of distortion

subjective intent

and resulting harm into a comprehensive analytical framework. On the regulatory pathway

it advocates a dual-track approach combining copyright law and anti-unfair competition law: the former applies where substantial similarity exists

while the latter governs "free-riding" conduct

that trades on the goodwill of the original work to mislead the public. This framework not only clarifies judicial reasoning but also provides institutional support for the sound development of the IP industry.
