According to the study conducted by international real estate consultancy JLL, the national capital Delhi is placed at 24th.

Two Indian cities -- Delhi and Mumbai -- have made it to a top-30 list of the world's most powerful, productive and connected cities.According to the study conducted by international real estate consultancy JLL, India's financial capital Mumbai has been ranked 22nd while the national capital Delhi is placed at 24th.The list is topped by Tokyo, which along with New York, London and Paris, make the top four 'super cities'. These four were the destination of over 50 per cent of all foreign capital invested in the Global Top 30 cities.JLL said its Top-30 global cities account for 64 per cent of the total cross-border investment into the 'Global300' - an expanded index of the cities in terms of their "commercial attraction" or economic and real estate power and status.Mumbai is also on the top-10 "improvers" list. Top-10 improvers are cities whose scores in the index of "commercial attraction" have improved the most over the past year.Other cities where commercial attraction has improved significantly include Milan (Italy), Istanbul (Turkey), Tehran (Iran), Madrid (Spain), Cairo (Egypt), Riyadh (Saudi Arabia), Lagos (Nigeria), Jakarta (Indonesia) and Jeddah (Saudi Arabia)."With growth exceeding 7 per cent in the city over each of the last three years, it is no wonder that Mumbai made a strong presence in the top list," JLL said, adding that reforms being undertaken by the national government are boosting confidence in the national and metro area economy.JLL further said Mumbai is enhancing its position as a hub for global corporations, with firms among the world's 2,000 largest companies headquartered in the city - rising by 50 per cent over the last 10 years.The index of commercial attraction is JLL's primary benchmark of the size and strength of a city's economy and real estate market.
