Dholera Special Investment Region (DSIR) is one of the first and the biggest of the eight manufacturing cities to be developed under Phase-I of the Delhi Mumbai Industrial Corridor and is planned to be the first and largest smart, sustainable “Greenfield industrial smart city” located approximately 100 kms south of Ahmedabad to cater to a population of two million, employing over 8,00,000 by 2042. Dholera SIR spanning approximately 920 sq km, encompassing 22 villages of the Dholera Taluka in the District of Ahmedabad, is envisaged to be bigger than the city of Ahmedabad. It is strategically located between the industrial cities of Ahmedabad, Baroda, Rajkot and Bhavnagar​.
It has been notified under the National Investment and Manufacturing Zone policy and obtained environmental clearance in August 2014.​
The 920 sq km of the Dholera Industrial City area has a total developable area of about 580 sq km since one third of the area falls within the Coastal Regulation Zone (CRZ) boundary where development is restricted and is as per CRZ norms. Out of the 580 sq km the prime agricultural land has been preserved and a total area of about 422 sq km has been set for urban development, which has been translated into six town-planning schemes and will be developed in three phases over a period of 30 years.​
Dholera’s city development area of approximately 5600 acres is under immediate development.​
The Dholera Special Investment Region Development Authority (DSIRDA) has the responsibility of planning and development of DSIR and will encompass the function of administering government land within DSIR. An SPV named Dholera Industrial City Development Limited (DICDL) has been created between the Central Government (DMICDC Trust) and the State Government (DSIRDA) of Gujarat to implement the project.​
Defence, Aviation, Electronics, High-Tech emerging technologies, Pharmaceuticals & Biotechnology, Heavy engineering, Auto & Auto ancillary, General Manufacturing, Agro & Food processing, Metals & Metallurgical products, etc. are the sectors identified with a high potential for Dholera Industrial City among other sectors. DSIR will be home to non-polluting industries, promoting a clean, green and sustainable urban development, which can contribute to the growth of the region and India.​
