In this study, the key sectors of Turkey are determined using Input-Output
(IO) network analysis. Different centrality measures are analyzed and
compared. Accordingly, eigenvector, page rank, hub, and authority
centralities are calculated. The effects of an economic shock are also
analyzed using random walk centrality and counting betweenness. Findings
indicate that the key sectors are ?Wholesale and Retail Trade; Repair of
Motor Vehicles?, ?Transport, Storage and Communications?, ?Agriculture,
Hunting and Forestry?, ?Construction?, ?Real Estate Activities?, and
?Textiles, Textile Products, Leather and Footwear?. Furthermore, the same
sectors are determined to be vulnerable to economic shocks.
