What might link these
The relationship between services value added and industrial roundwood import value may be driven by countries' overall economic development and trade activity. A careful reader should consider the potential role of urbanization, as more urbanized countries may have both higher services value added and greater demand for imported wood products. Education level could be a likely confounder.
Why this is not proof of anything
This is a correlation across countries, not an experiment. It cannot show that either indicator causes the other, and both may simply follow a third thing. This correlation could mislead by implying a direct link between the two indicators, when in fact they may both be driven by underlying factors like economic development.
The second figure above repeats the measurement with national population and income held constant. It is the more conservative number: a relationship that largely disappears there was mostly telling you that larger, richer countries have more of most things.
How this was measured
Both indicators were ranked across every country reporting each, and the two rankings compared — ranks rather than raw values, because a handful of very large countries can otherwise manufacture a relationship on their own. The calculation is arithmetic over figures already published on this site; the commentary above is drafted from the two indicator names and the resulting coefficients.
