2．Beijing's annoying smog（雾） seems to have hurt the city's appeal to tourists．Last year，Beijing Youth Daily reported that the number of visitors to Beijing （33）had fallen（fall） 50percent since January．It's said that the city's bad air quality was to blame for the decline．It's also more difficult （34）to attract（attract） high-end employees to work in Beijing，especially those with children．
However，the blanket of poisonous smog hasn't hurt Beijing's office market，（35）which has jumped up quickly on a global ranking to become the fourth-most-expensive location to rent office space in the world．According to a recent research，office space in Beijing's Central Business District costs （36）on average $1，412per square meter per year．
That's more expensive than No.5-rankes central Tokyo or No.6-rangked Madison & Fifth Avenues in New York．The research took into consideration both （37）published （publish） rental rates and"additional costs，"which include agent fees and （38）othercosts to make the deal happen．
London （39）remains （remain） the world's most expensive city in which to rent office space．Hong Kong，home to the priciest office space in Asia，comes in second globally．The cities （40）experiencing（experience） the highest annual growth in office rental rates are both in South Africa with 40percent rate rise for Durban and 44percent for Sandton．
