摘　　要：研究不同收入群体进口价格指数对衡量各收入群体生活成本变动和揭示国际贸易价格效应至关重要。通过构建异质性视角下特定收入群体进口价格指数的结构性理论框架,并结合替代弹性混合估计方法,利用CEPII-BACI进口产品数据和城镇住户调查数据,首次测算了中国不同收入群体的进口价格指数,分析了不同收入群体进口价格通胀程度。研究结果表明:各收入群体进口价格指数整体处于上升趋势;中等收入群体和低收入群体经历了更高的进口价格通胀,工业制成品进口价格指数的快速增长是低收入和中等收入群体经历更高进口价格通胀的主要原因。在实施扩大进口战略和构建双循环新发展格局的同时,需要防止进口价格上涨对低收入和中等收入群体生活成本造成较大负面冲击和加剧其脆弱性,实施相应的公共福利政策,增强其应对贸易冲击的能力。Studying the import price index of different income groups is crucial for the measurement of the changes in the living costs of different income groups and for the revelation of the price effect of international trade. By constructing the structural theoretical framework of import price index for specific income groups from the heterogeneity perspective and combining the alternative elastic hybrid estimation method, this paper makes use of the data of import products from CEPII-BACI database and the data of Chinese Urban Household Survey to measure the import price index of different income groups and analyze the degree of import price inflation of different income groups in China for the first time. The findings show that the import price indexes of different income groups have an upward trend. The middle-income groups and the low-income groups have suffered the highest import price inflation, and the rapid increase of the import price index of manufactured goods is the main reason forthe low-and middle-income groups suffering higher import price inflation. While implementing the strategy of expanding imports and building a new dual-cycle development pattern, it is necessary to prevent the rise in import prices from causing a greater negative impact on the cost of living of the low-and middle-income groups and aggravating their vulnerability;and the corresponding public welfare policies should be implemented, so as to strengthen their ability of response to trade shocks.
