Companies in this industry act as agents in the buying, leasing, and selling of commercial real estate. Major companies include CBRE Group, Colliers International, Cushman & Wakefield, Jones Lang LaSalle (JLL), and Newmark Grubb Knight Frank (all US-based), as well as Countrywide and Savills (both in the UK) and E-House China Holdings.
Demand, which is driven by the volume of commercial real estate transactions, is heavily influenced by real estate vacancy rates. The profitability of individual companies depends on efficient operations. Large companies have advantages in performing a range of services in multiple markets. Small companies can compete effectively by specializing in local markets. The US industry is concentrated: the 50 largest companies account for about half of industry revenue.
