讲座摘要：
经合组织支柱一方案：OECD/G20针对跨国公司税基侵蚀和利润转移的措施（2015年）在重新定义国际税法的规则和规范方面相当成功。然而，对大型科技公司的有效征税只在后续行为中通过第一支柱方案（2019年）得到解决。尽管该方案被扩大到包括所有最大的跨国企业（2020年），但此种做法仍有争议。争议中最有趣的部分是有人主张这背离了独立交易原则—而这正是公司跨境征税的长期基础。
经合组织支柱二方案：OECD/G20 税基侵蚀和利润转移措施（2015年）在增强跨国公司税收的有效性方面做了很多工作，例如混合错配规则和受控外国公司规则都依赖于这种方法，即"如果你不征税，就由我来征"。这种方法是务实的，因为它不需要就税基定义达成国际共识，并降低了对反滥用原则的依赖，支柱二方案（2019年）正是这种实用主义的普遍应用。但是，同时它也带来了新的困难和挑战，特别是难以就衡量有效税率问题达成国际共识。
OECD Pillar 1 proposal. The OECD/G20 measures against Base Erosion and Profit Shifting by multinational firms (2015) were quite successful in redefining the rules and norms of international tax law. However, effective taxation of Big Tech firms was only addressed in the follow-up: the Pillar 1 proposal (2019). The proposal is still controversial, despite its being broadened to include all the largest MNEs (2020). The most interesting element in the debate is the departure from the arm’s length principle – the longtime foundation of cross-border taxation of companies.
OECD Pillar 2 proposal. The OECD/G20 BEPS measures(2015) have done much to restore the effectiveness of taxation regarding multinational firms. E.g., both hybrid mismatch rules and Controlled Foreign Corporation rules rely on the approach: “if you don’t tax it, I will”. This approach is pragmatic, as it does not require international consensus on tax base definition, and reduces the need to rely on anti-abuse doctrine. The Pillar 2 proposal (2019) is a more general application of this pragmatism. It does, however, create new and difficult challenges, esp. reaching an international consensus on the measurement of effective tax rates.
