法經濟學視野下版權合理使用與技術保護措施之衝突與協調

The Conlfiction and Coordination of Copyright Fair Use and Copyright Technical Protection Measures in the Internet Age Which Based on the Economics

隨著數字和網絡技術的發展，合理使用制度面臨著嚴峻的挑戰。技術保護措施侵蝕了合理使用的空間，基於交易成本的市場失靈和價格區分理論也被用來作為否定合理使用的工具。基於交易成本的市場失靈和價格區分理論的運用有利於版權交易，但是，這不意味著合理使用制度已不再重要。在技術保護措施盛行的今天，合理使用制度可以確保作品正外部性的充分發揮，防止版權過於膨脹。未來網絡時代的版權法需尋求技術保護措施與合理使用制度之間的協調，探索合理使用制度在網絡環境中新的適用方式。

With the development of digital and network technologies, fair use doctrine is facing severe challenges. Technological protection measures eroded the space of fair use, market failure based on the trade costs and price discrimination theory is also used as a tool to negate the fair use doctrine. Market failures based on the trade costs and price discrimination theory has some values to copyright trade, but this does not mean that the fair use doctrine is no longer important. As the technical protection measures more popular nowadays, more needs should be paid to the fair use doctrine to ensuring that works can fully play its positive externalities, preventing over-expansion of copyright. In the internet age, the future of copyright law need to coordinating between technical protection measures and fair use, exploring the new forms of fair use doctrine in a network environment.
