“…Previous studies, which investigated a shorter chain of the biogeochemical Hg cycle from economic activities to atmospheric Hg emissions and deposition, illustrated the spatial relocations of atmospheric Hg emissions and deposition over China, but showed ignorable net impacts of interprovincial trade on the Hg pollution over the whole of China 12,17,18,35 . In this study, we reveal that interprovincial trade not only changes the spatial distribution of Hg pollution over China but also considerably changes the Hg-related health risks across the whole country.…”

“…Investigating a longer chain of the biogeochemical Hg cycle from economic activities to human health in this study provides more scientific foundations for the reduction of Hg-related health risks than previous studies investigating a shorter chain of the biogeochemical Hg cycle from economic activities to atmospheric Hg emissions and deposition 12,17,18,35 . First, investigating a longer chain can provide a map of Hg-related health risks in China for the first time.…”

Mercury (Hg) exposure poses substantial risks to human health. Investigating a longer chain from economic activities to human health can reveal the sources and critical processes of Hg-related health risks. Thus, we develop a more comprehensive assessment method which is applied to mainland China—the largest global Hg emitter. We present a map of Hg-related health risks in China and estimate that 0.14 points of per-foetus intelligence quotient (IQ) decrements and 7,360 deaths from fatal heart attacks are related to the intake of methylmercury in 2010. This study, for the first time, reveals the significant impacts of interprovincial trade on Hg-related health risks across the whole country. For instance, interprovincial trade induced by final consumption prevents 0.39 × 10 −2 points for per-foetus IQ decrements and 194 deaths from fatal heart attacks. These findings highlight the importance of policy decisions in different stages of economic supply chains to reduce Hg-related health risks.

“…where diag(ε) represents the diagonal matrix composed of ε i , f ij stands for the IMP flow from sector i to sector j directly (i.e., sector j consumes the intermediate IMP-related products supplied by sector i) [17,29]. Thus, F j = n i=1 f ij stands for the indirect consumption of sector j, and F i = n j=1 f ij is the indirect supply of sector i.…”

Raw milk powder is one of most important raw materials for dairy processing and manufacturing. In the past decade, the rapid growth of imported raw milk powder (IMP) consumption has brought about significant impacts on China's social economy. For more in-depth analysis of such impacts, this study develops a comprehensive IMP consumption model for China covering 2007-2015 based on the input-output analysis method from the perspective of material metabolism. In detail, material flows and consumption analysis are employed to reveal the direct and indirect IMP consumption and supply of various sectors. Using an innovative hierarchy analysis and network utility analysis, the internal structure of the IMP consumption system and consumption relationships between different sectors are identified. Due to the increasing intensive production activities between the manufacture and processing of the dairy products sector and others, its downstream sectors have grown rapidly and the consumption relationships with others are mostly mutualism. The surge in IMP has caused dramatic changes in consumption relationships, which has the greatest impact on the service sectors, followed by manufacturing sectors. The rapid increase in IMP consumption has put great pressure on the supply and consumption of intermediate products of many sectors.

Environmentally Extended Input–Output Databases (EEIOs) provide an effective tool for assessing environmental impacts around the world. These databases have yielded many scientific and policy relevant insights, especially through the national accounting of impacts embodied in trade. However, most approaches average out the spatial variation in different factors, usually at the level of the nation, but sometimes at the subnational level. It is a natural next step to connect trade with local environmental impacts and local consumption. Due to investments in earth observation many new data sets are now available, offering a huge potential for coupling environmental data sets with economic models such as Multi-Region Input–Output (MRIO) models. A key tool for linking these scales are Spatially Explicit Input–Output (SIO) models, which provide both demand and supply perspectives by linking producers and consumers. Here we define an SIO model as a model having a resolution greater than the underlying input–output transaction matrix. Given the increasing interest in this approach, we present a timely review of the methods used, insights gained, and limitations of various approaches for integrating spatial data in input–output modeling. We highlight the evolution of these approaches, and review the methodological approaches used in SIO models so far. We investigate the temporal and spatial resolution of such approaches and analyze the general advantages and limitations of the modeling framework. Finally, we make suggestions for the future development of SIO models.
