Aging Populations Pull RCEP Nations Closer in Medical Device Trade Network

Population aging is quietly reshaping the geography of medical device commerce across the Asia-Pacific. A new study of the Regional Comprehensive Economic Partnership (RCEP) finds that as member countries grow older, they become more deeply embedded in the region's medical device trade network, a shift driven mainly by sharper export specialization and more consolidated import sources. Researchers from Shandong University at Weihai and Shandong University analyzed trade data covering all 15 RCEP member countries from 2004 to 2023.

They constructed a regional medical device trade network and computed a network embeddedness index for each member, then examined how rising shares of elderly populations affected that index over time. The structural picture that emerges is of a dense, tightly connected and decentralized network. The authors report that the RCEP medical device trade network exhibits high density, strong connectivity and low centralization, meaning that trade linkages are spread broadly across members rather than funneled through a few dominant hubs.

Those linkages, they find, have continued to deepen over the two decades studied. Against that backdrop, the central result is clear: population aging significantly increases a member country's embeddedness in the network. In other words, countries with faster-growing elderly populations tend to occupy more central, more interconnected positions in the regional web of medical device trade.

The mechanism analyses point to two channels behind this effect. At the same time, it consolidates import sources, as aging economies streamline and concentrate where they buy devices from. Both processes knit a country more tightly into the regional network.

The effect is not uniform across the region. Heterogeneity analyses show the positive impact of aging on embeddedness is more pronounced among non-ASEAN members, among developing countries, and among economies already at advanced stages of population aging. These findings provide important policy insights for RCEP member countries seeking to respond to population aging, strengthen public health security capacity, and advance trade cooperation in the health and medical device sectors.

The authors frame the results as policy insights for RCEP members seeking to respond to population aging while advancing trade cooperation in the health and medical device sectors. The study is published in Frontiers in Public Health in the Health Economics section, authored by Xinyi Li, Leran Ge and Wen Liu.
