Productivity growth depends not only on technological innovation but also on production networks that amplify its impact. Theory and cross-country evidence indicate a positive relationship between productivity growth and the use of intermediate inputs, a measure of network connectedness. We find that Chile’s intermediate input utilization is significantly lower than that of OECD peers, such as Korea and the Czech Republic, and declined during 2008-21. This is primarily due to weak domestic producer connections and the smaller presence of the manufacturing sector. We argue that diversifying exports from mining, reducing trade costs, and improving contract enforcement could strengthen network linkages and boost growth.
