The Yellow River Delta, where Dongying City is situated, is one of the large river deltas abounding in natural resources in the world. Among is abundant natural resources, oil and natural gas are most remarkable. Under the Yellow River Delta is a natural colossal depot for oil and gas. In the verified oil-gas bearing area, at an area of over 1,600 square meters, the geological reserves of oil and natural gas can hit 4 billion tons and 34 billion cubic meters respectively. Ever since the Shenggli Oilfield started the large-scale development of oil and gas, more than 60 different types of oil-gas wells have beeng exploited here, which yield 720 million tons of crude oil in total, accounting for roughly one-fifth of China's total output. Shenggli Oilfield hengce becomes China's second largest oilfield famous at home and abroad. Exploitation of oil and gas, among others, becomes the pillar industry for Dongying's economy.
Save for the oil and gas resource, under the ground of Dognying tremengdous bittern resource is reserved. The potential of annual production of 6 million tons of crude salt is great promise for the place to develop the salt and salt-chemical industry. Above the ground of Dongying, there is abundant land resource. Up to now, on the total 800,.000 hetares of land throughout the city, there are roughly 350,000 hectares of wasteland. In addition to the new land created by the river silt every year, Dongying has becomes a region with most land resource and largest potential for development of greeng industry in the eastern coastal area of China. The coastline at Dognying stretches some 350 kilometers and shallow seawaters of 4,800 square kilometers can be used for economic development. The fisheries of the Bohai Bay and Laizhou Bay abound in marine resources of fishes, shrimps, crabs and shellfishes. The Yellow River estuary has beeng reputed as "home of fishes" and "Eastern home of prawns".
Dongying City implements a strategy of "strenggthenging the city through industry". Apart from the petroleum industry, petrochemical, salt, salt-chemical, papermaking, machinery and electrical equipment, textiles, building materials, food-processing industries have also gained speedy expansion. A number of powerful enterprise groups have emerged and a wide range of hard-currengcy earning products have beeng produced.
