高緯環球諮詢公司歐洲研究小組合夥人兼負責人戴維·哈欽斯（David Hutchings）在報告中說：“佔領者對優質空間有著明顯的偏好，但是在越來越多的城市中，許多人都遇到了供應限制。” “這推動了租金的增長，而佔用者將不得不比預期更快地採取行動，以確保在可用的優質空間數量減少的情況下達成交易。”
The office market in Jakarta is forecast to witness the highest rental rate growth through 2015, with rents on track to increase almost 30 percent, according to Cushman & Wakefield.
The Indonesia capital leads the global office market growth forecast for the second year in a row, with rates more than double the level in 2011. The growth already seen in Jakarta has positioned it as Asia's hottest market
The Dublin and Boston office markets rank second and third, respectively, and join Jakarta as the regional leaders among the top cities forecast for highest rental rate growth in the next two years.
San Francisco ranks fourth, with London, Singapore, Tokyo, Seattle, Manila and New York rounding out the top 10 global markets.
As a whole, the global office market is expected to record steady growth in 2014, with a more robust market in 2015 with continued recovery and renewed confidence in business gains, according to the report.
"Reduced occupancy footprints and an upgrade to better quality space are two global trends that show no sign of letting up anytime soon," said Carlo Barel di Sant'Albano, executive chairman of Cushman & Wakefield. "The workplace is becoming more complex and inter-related with business performance and objectives, with modern efficient space seen as promoting increased productivity and workplace satisfaction. In certain instances, new construction can achieve both goals."
In the Americas, technology and energy continue to be main drivers for the U.S. real estate recovery, with Boston forecast for 22 percent increase in prime asking rents. On the other hand, Canada, Mexico and Brazil are expected to witness an oversupply of office space, with widespread rental growth in Brazil not expected until 2016.
Cities such as London, Stockholm and Frankfurt have led the European leasing recovery, but are now joined by the formerly distressed margin. Dublin, one of the hardest hit markets, has recovered with double-digit rental growth anticipated.
"Occupiers have a clear preference for quality space but many are encountering supply constraints in an increasing number of cities," David Hutchings, partner and head of Cushman & Wakefield's European research group, said in the report. "This is pushing rental growth and occupiers will have to move sooner than expected to secure deals on the decreasing amount of quality space that is available."
More subdued growth is forecast for Asia Pacific, with rents expected to grow by 1 to 2 percent over the next year. As rents reach high marks in central business districts, businesses are looking for low-cost options outside, while upgrading to new construction at the same time, the report says.
"With the abundance of new supply especially in the emerging markets, it remains a great time to be an occupier," Sigrid Zialcita, managing director of research for Asia Pacific, said in the report.
