Is the Global Economy Deglobalizing? If So, Why? And What Is Next?
分析2008年金融危机后全球化放缓但未逆转的趋势，探讨贸易政策、疫情和地缘政治对全球化的影响，指出新政策可能减缓全球增长、创新和减贫。
ABSTRACT: Data on global trade as well as capital and labor flows indicate a slowdown, but not reversal, of globalization since the 2008–2009 financial crisis. Yet profound changes in the policy environment and public sentiment in the largest economies over the past five years suggest the beginning of a new era. Increasing anxiety about the labor market effects of import competition from low-wage countries, especially China, laid the groundwork but was not the catalyst for the reversal in attitudes toward globalization. Similarly, the COVID-19 pandemic provided novel arguments against free trade based on global supply chain resilience, but neither the pandemic nor short-run policy response had enduring effects on trade flows. We demonstrate that global trade was remarkably resilient during the pandemic and that supply shortages would likely have been more severe in the absence of international trade. After a temporary decline in 2020, global trade in goods and services increased sharply in 2021. Russia's invasion of Ukraine raised new concerns about national security and the exposure of supply chains to geopolitical risk. This was followed by demands to diversify away from "non-friendly" countries and toward the employment of trade policy, export restrictions in particular, to halt China's technological development. The future of globalization is highly uncertain at this point, but these new policies will likely slow global growth, innovation, and poverty reduction even if they benefit certain industries in certain countries. Regarding resilience, the main goal of recent trade policy changes, measures of trade volatility or concentration can be helpful, but resilience will be elusive as long as we lack benchmarks against which policy performance can be measured.
