The subsidies - to be at least 500,000 yuan but no more than 30% of the total project investment - must be issued by the end of 2020, the National Development and Reform Commission (NDRC) said in a statement on its website.
They can also be issued to farms seeking to expand, with the funds aimed at helping producers cover the cost of equipment for disease prevention, waste treatment, environmental controls and automated feeding.
The move comes as official figures show China’s hog herd, the world’s largest, has shrunk by almost a third since a year ago, after deadly African swine fever swept across the country.
Many people believe the losses to be much higher, however, at about half the herd.
Pork prices began rising sharply in June in response to the reduced supplies, reaching a fresh record last month, and Beijing has warned that they will go higher, threatening to become a serious concern for low-income consumers.
“The top 40 or 50 producers will take advantage of this for sure,” said Ron Lane, sales director at Big Dutchman, a German farm equipment firm with operations in China.
Construction of a modern farm costs between 10,000 yuan and 12,000 yuan per sow, he said, without including the costs for the pigs themselves or the land.
That means about 20% of the construction costs for a 2,000-sow farm could be covered, he added, although for the larger 5,000-sow farms more common among the leading producers, the subsidy would cover a smaller percentage of the costs.
China’s vice premier has repeatedly urged provincial authorities to ensure sufficient pork supplies and boost a recovery in hog production.
But despite a series of new policies issued by ministries, including an easing of restrictions on land permits and offering farmers low-interest loans, risks remain high, say experts, with African swine fever still spreading in the country.
There is no vaccine and no cure for the disease, which kills almost all pigs it infects.
