(Yicai Global) Dec. 18 -- The finance arm under Chinese e-commerce giant JD.com Inc. [NASDAQ:JD] has struck a deal to offer its technology and services to Guoyuan Securities Co. [SHE:000728] .

The pair penned an agreement to create a 'finance + technology' ecosystem, the securities brokerage said on Dec. 15.

Under the deal, the two firms will develop the content and functions of JD Finance's platforms and use Big Data, artificial intelligence and cloud computing to apply its fintech where needed, the statement said. Such applications include risk control, credit data and payment services.

The biggest source of debt for China's residents comes from mortgages, but the rise of consumer spending cannot be ignored. The desire to spend more on non-necessities has seen an array of fintech companies setting up shop over the past 18 months and four of them going public in the US this year, although their questionable business ethics have seen sharp declines in their stock prices.

The partnership will help Guoyuan offer a better range of financial services, improve customer service levels and enhance brand influence, the brokerage added.
