The use rights of 340 million mu (22.7 million hectares) of farmland had been transferred to larger farming entities as of the end of 2013, the Ministry of Agriculture said on Sunday.

The transferred land accounts for[Hong Kong Company Registration Guide] 26 percent of the farmland under "the household contract responsibility system", said Zhang Hongyu, a senior official of the ministry.

The transferred acreage tripled the size at the end of 2008, he added.

The use rights of the majority of China's collectively-owned farmland were split and allocated to farmers under the household contract responsibility system introduced in 1978, when the country started a sweeping rural reform ending communal farming.

Over 2.87 million farmers operated farmland larger than 50 mu, and more than 870,000 family farms [Businesses Registration]had been established nationwide as of the end of last year, according to Zhang.

He said that the transfer of farmland went too fast in some areas, and need to be carried out more steadily.
