Its important agricultural produces include cotton, rice, cocoon, corona oil, etc. Sufficient supplies and produces of sea foods and veges harvested from oceanic water and its shadow beaches have given the county a remarkable wealth.

The economic expansion over years has added numerous new sectors to the county’s industry, including texture, biomedical, mechanic and electronic industries. The fishing industry relies on the East China Sea and even wider Pacific Ocean. The fast development of Yangkou Port would further enhance the county’s oceanic transportation capability. The city has been ranked at 86th on the list of China’s Top 100 Counties (county-level cities) for its comprehensive economic strength.

Rudong has established two industrial zones, Rudong Economic Development Zone and Yangkou Port Development Zone, to attract more investment funding.

In 2007 Singapore RGM International signed an agreement with the city to invest $1.33 billion USD in total for a renovation project for the port.

The local municipal government has been putting stiff environmental rules into practice over years and has spent substantial funds to protect its environment. The city has been honored as one of the green cities in China.

Dubbed a "Pearl of Southern East Sea", Rudong is a land formed by the enoumous sand deposit brought by the Yangtze River in a history of more than 2,000 years. The Rudong Yangkou Port would be one of the most prestigious seaports in the East China Sea in the coming decade.
