Primorsky Krai's economy, the most balanced in the Russian Far East, is also the largest in absolute terms. Food production is the most important sector, represented mainly by fish processing. Annual catch exceeds two million tonnes, or one half of the Russian Far East total. Second is machine building, where half of the output is geared toward the fishing industry and shipyards. Defense is another important sector, producing naval vessels and military aircraft. The construction materials industry here provides for the whole Russian Far East. Lead smelting is conducted in the coastal town of Rudnaya Pristan.

The timber industry, though in recession, is still second only to Khabarovsk Krai's with an annual yield of about 3 million cubic meters of timber. Primorsky Krai is the largest coal producer in the Russian Far East and generates more electricity than any other Russian Far East administrative division, but power shortages are common. Agriculture is also important; the Krai produces rice, milk, eggs, and vegetables.

Primorsky Krai is the Russian Far East's banking and finance center. It has more than 100 banks and affiliates and well-developed futures and stock exchanges.
