平臺經濟領域的反壟斷法實施，以經濟效率目標為出發點

在平臺經濟領域，歐盟和美國反壟斷法實施力度有很大差異，中國也明顯呈現出兩個階段。這種差異需要解釋，而經濟效率目標構成了理解的出發點。通過福利標準，經濟效率目標建立了統一、確定的分析框架。但這一分析框架也受到諸多因素的約束，並面臨平臺經濟的挑戰。《反壟斷法》雖然明確了經濟效率目標，但沒有清晰的福利標準。當前對平臺企業的高強度執法，更多是追求非經濟效率目標的結果。作為多目標法律，非經濟效率目標使得《反壟斷法》更具現實回應性。不過，要實現更好的實施效果，仍需要完善的反壟斷法制度，並在個案中進行更充分地說理。

"In platform economy, there are great differences between the EU and the US interms of the enforcement of antitrust laws. China has experienced two stages as well. The differences need to be further explained. Considering the importance of goal for antitrust law, the goal of efficiency becomes a proper starting point. By the welfare standard, a unified and definite framework can be created for the goal of efficiency. Meanwhile, this analytical framework is also determined by many factors, and faces the challenge of platform economy. Although the Anti-Monopoly Law upholds the goal of efficiency, it does not have a clearly defined welfare standard. Currently, the active law enforcement targeting the platforms is the result of pursuing the goal of non-efficiency, which makes the Anti-Monopoly Law aiming to achieve multiple goals, become more responsive to reality. However, to achieve better implementation, it is required to improve anti-monopoly law and to make more thorough reasoning in specific cases."
