Small Industries Development Corporations (SIDCOs) are state-owned agencies established in Indian states to promote small-scale industries. SIDCOs aim to stimulate growth in small industries by providing infrastructure like roads, electricity, and water, as well as developing industrial estates with production sheds and facilities. They also offer technical training and help establish skills training institutes. SIDCOs undertake activities from industry installation to production start-up, such as supplying raw materials, marketing assistance, export help, and financing. Their assistance has helped develop previously backward areas and spread industry throughout states.
