港澳回归后，粤港澳大湾区利用其独特的地理优势，三地之间合作不断深化，各种社会、政治、经济交往的频繁进行，形成了复杂的区际社会、经济、法律关系。港澳拥有相对独立的立法权和司法管辖权，可以制定和执行相关的知识产权法律。三地不同的立法风格以及历史因素的影响，造成三地的知识产权实体法律存在较大差异。其次，港澳政府还可以用中国香港、中国澳门名义与不同国家地区或者组织之间，在经济、文化、科技、贸易等非国防外交领域开展交流合作，也可以加入或者签订相关的条约协议。对于中国政府加入的国际公约、协议等，在向特区政府征询意见后，根据实际发展需求，再决定是否对港澳生效。对于中国政府原来没有参加的，而港澳已经参加的国际条约、协议可以继续生效保留，这就为三地参加不同条约之间的冲突埋下了伏笔。通过借鉴国际湾区法律冲突解决经验，结合我国实际国情，从观念层面差异、实体层面法律差异以及条约冲突三方面展开论证，以期望为我国大湾区解决知识产权法律冲突纠纷提供解决思路。

After the return of Hong Kong and Macao, the Guangdong-Hong Kong-Macao Greater Bay Area has taken advantage of its unique geographical advantages to deepen cooperation between the three places, and various social, political and economic exchanges have been frequently carried out, forming complex inter-regional social, economic and legal relations. Hong Kong and Macao have relatively independent legislative power and jurisdiction, and can formulate and enforce relevant intellectual property laws. The different legislative styles and historical factors of the three places have caused great differences in the substantive laws of intellectual property rights in the three places. Secondly, the Hong Kong and Macao governments can also use the name of Hong Kong, China, and Macao to carry out exchanges and cooperation with different countries, regions or organizations in non-defense diplomatic fields such as economy, culture, science and technology, and trade, and may also join or sign relevant treaties and agreements. With regard to international conventions and agreements to which the Chinese Government is a party, after consulting with the Hong Kong and Macao’s Government, it will decide whether to take effect for Hong Kong and Macao on the basis of actual development needs. For international treaties and agreements to which the Chinese Government did not participate in the past, but to which Hong Kong and Macao have already participated, they can continue to enter into force and reserve, which lays the groundwork for the three places to participate in conflicts between different treaties. By drawing on the experience of conflict-of-law resolution in the international Bay Area and combining China's actual national conditions, we will carry out arguments from three aspects: differences in concepts, legal differences at the substantive level, and conflicts of treaties, in order to provide solutions for the resolution of intellectual property legal conflicts disputes in China's Greater Bay Area.
