Bucharest is the top business center in Romania, producing 24% of the country's GDP while being home to only about 9% of the country's population. After the collapse of communism, the city's solid economic development has revitalised infrastructure and led to the construction of shopping centers, residential units, and multi-storeyed office buildings. Currently, the local economy is centred on services and industry, with services being significantly important during the last decade. The HQs of 186,000 firms are located in the city. These include the representatives of practically all of Romania’s businesses. Bucharest, as the business center, is often chosen as an event destination, as it hosts numerous conference facilities and convention centers, historical and unique venues. The city's commercial real estate market also boasts a range of serviced office solutions, highly-valued among starting and developing companies. In recent years, Romania's capital has established itself as an IT outsourcing hub; that's why the majority of the business centers in Bucharest accommodate technology firms and corporations. Transport accessibility is another perk of the location. The area is served by two international transport corridors - Pan European IV and IX. Also, Bucharest has the most-extensive public transport network in the country. Two airfields ensure air connections.
