In 2017，proprietary asset of the trust industry kept a steady expansion，and proprietary business revenue regains a positive growth. However，there is no significant change in the proprietary asset structure. Due to the market condition and the faster growth of net asset，the return on proprietary equity continues to decline.

Proprietary business has an increasing support to the trust business and hence generally losses its independence.
