This study adopts a mixed-methods research design, using the coffee industry in Yunnan, China, as a case study to reveal the micro-level mechanisms by which domestic demand drives industrial upgrading. Building on these case-derived mechanisms, it then uses panel data from 96 major coffee-producing and coffee-consuming economies from 2012 to 2024 to examine their macro-level implications, including national-level relationships, nonlinear patterns, and cross-country heterogeneity. The study shows that both factors generally drive export upgrading and exhibit a \u201cpromotion\u2014inhibition\u2014re-promotion\u201d pattern characterized by a dual-threshold nonlinearity. The case study reveals that the inhibition phase stems from a mismatch between market expansion and demand structure upgrading, where homogeneous capacity growth temporarily offsets the effects of quality upgrading. Heterogeneity manifests in three distinct patterns: producing countries exhibit only a significant domestic market absorption effect; traditional consuming countries are primarily characterized by path dependence; and emerging consuming countries achieve dual-driven growth in both scale and quality. By bridging macroeconomic effects and microeconomic logic, this study clarifies the conditions under which domestic demand drives product-end upgrading along the value chain, providing a reference for different economies to formulate differentiated upgrading strategies.<\/jats:p>","DOI":"10.3390\/foods15183240","type":"journal-article","created":{"date-parts":[[2026,9,14]],"date-time":"2026-09-14T09:34:01Z","timestamp":1789378441000},"page":"3240","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["How Domestic Demand Drives Coffee Export-Basket Upgrading: Pathways to Agri-Food System Transformation"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-6877-9359","authenticated-orcid":false,"given":"Ying","family":"Hu","sequence":"first","affiliation":[{"name":"School of Economics, Yunnan University, Kunming 650504, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"software","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]},{"given":"Yongle","family":"Xie","sequence":"additional","affiliation":[{"name":"School of Economics, Yunnan University, Kunming 650504, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"validation","vocabulary":"credit"},{"role":"software","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"117","DOI":"10.1080\/713600071","article-title":"Globalisation and unequalisation: What can be learned from value chain analysis?","volume":"37","author":"Kaplinsky","year":"2000","journal-title":"J.
