Deglobalization and elevated inflation are important features of the current world economy. Will the reversing of globalization affect the level and formation mechanism of inflation in the countries (or regions)? This paper selects 163 sample economies and constructs an index system in measurement of globalization. On such basis, it integrates the index system into the hybrid Phillips curve under the condition of open economy to study the influence of globalization on inflation and the logical mechanism and to further evaluate the driving effect of deglobalization on global inflation. The result shows a deflation effect of globalization, and the effect decreases first and then grow as the globalization level of a country (or region) improves. To further investigate the formation mechanism of inflation, the paper decomposes inflation into inflation trend and inflation cycle. As far as inflation trend is concerned, trade globalization marked by participation in global value chain is the main driver of downward inflation trend in developed economies, while globalization of information and finance is the primary driver of downward trend in emerging and developing economies. As to inflation cycle, trade globalization makes inflation cycle of the countries (or regions) more sensitive to price of international commodities and forms a linkage through trade network. Since the outbreak of the major public health emergency in 2020, the reversing of globalization drove up inflation of the countries (or regions), and those with higher participation in global value chain have higher level of inflation.
