【广发宏观郭磊】继续改善的价格弹性

Core Viewpoint - The article discusses the trends in CPI and PPI for December 2025, highlighting a month-on-month increase of 0.2% for both indices, with PPI marking its fifth consecutive month of positive growth. Year-on-year, CPI and PPI are reported at 0.8% and -1.9%, respectively, exceeding previous model predictions [1][4]. CPI Analysis - The month-on-month CPI increase of 0.2% is attributed to various sectors, with negative growth observed in pork, alcoholic beverages, rent, fuel, and traditional Chinese medicine. Positive growth is noted in fresh vegetables, fruits, medical services, gold jewelry, and durable goods [6][7]. - Durable goods prices showed significant improvement, particularly in household appliances, which saw a historical high month-on-month increase of 1.4% in December, likely influenced by seasonal factors and PPI transmission [6][8]. - Transportation tools experienced a month-on-month increase of 0.1%, above the ten-year average of -0.15%, possibly due to stabilization in car prices amid a "de-involution" context [6][8]. PPI Analysis - The month-on-month PPI increase of 0.2% is driven by a 0.8% rise in the mining industry, marking its fifth consecutive month of positive growth. Raw materials and processing industries also saw increases of 0.6% and 0.2%, respectively, the fastest rates of the year [2][9]. - In the living goods category, while food and durable goods continued to show negative growth, clothing and general daily necessities recorded increases of 0.2% and 0.5%, respectively, marking the second-highest points of the year [2][9]. - Specific industries showed price differentiation, with rising prices in coal mining and processing, contributing significantly to PPI growth. Additionally, prices in lithium-ion battery manufacturing and cement production increased by 1.0% and 0.5%, respectively [10][9]. Future Outlook - The article suggests that the simulated deflation index is expected to rise gradually after hitting a low in July 2025, correlating with the timing of increased "de-involution" efforts. The central economic work conference indicates that addressing "involution" will be a key focus for 2026 [3][11]. - Historical economic cycles indicate that periods of nominal growth elasticity, such as 2006-2007 and 2010-2011, are characterized by strong internal demand stimulation. The outlook for 2026 suggests potential benefits from external demand due to fiscal expansions in developed economies and industrialization in developing countries [3][11].
