Yuzhou is not the only place that boosted the local economy through industry clusters.

About 300 kilometers away from Yunzhou, Kelan county in Xinzhou city of Shanxi province is stepping up efforts to promote a sea buckthorn plantation and related businesses to create new momentum for local economic development.

Kelan's development of the sea buckthorn business benefited from its abundant natural sea buckthorn resources. To date, Kelan has 490,000 mu of wild sea buckthorns in the county for local companies to process into various products.

Kelan-based Shanxi Songjiagou Functional Foods Co Ltd is harnessing 200,000 mu of local wild sea buckthorns to create more value from the nutritious fruit.

"Sea buckthorn has an impressive nutritional profile, including various vitamins, anti-oxidants, anti-inflammation properties and many other nutrients. The fruit is good for health in many ways, and our company is stepping up efforts to research and develop more of its uses, with joint efforts from research labs in various institutes," said Zhang Yanfeng, general manager of Shanxi Songjiagou Functional Foods.

The company is making sea buckthorns into herbal tea, functional drinks and dietary supplements. The value of sea buckthorns per metric ton will increase about 10 times after being processed into functional products, Zhang said.

"China has over 90 percent of the world's sea buckthorns, and 70 percent of the wild sea buckthorns in China are from Shanxi. We hope to fully leverage the regional resources," Zhang said.

"The local government has rolled out a series of supportive measures, such as improved infrastructure, implemented tax cuts, and gave us 1 million yuan in research subsidies per year for three consecutive years to support our business," Zhang said.

While making a fortune through Kelan's sea buckthorn resources, Shanxi Songjiagou Functional Foods is also contributing to poverty alleviation. It offered help to over 717 local families, the company said.

Sea buckthorn businesses are just one part of Kelan's concerted efforts in poverty alleviation.

The county has been promoting businesses in six traditional industries including planting potatoes, herding goats and sheep, and developing new businesses like photovoltaic, Chinese traditional medicine herbs, and tourism to help boost employment and reduce poverty.

In 2019, the annual disposable income for people who used to live in poverty hit 11,042 yuan per person, much higher compared with the 2,989 yuan in 2014.

Zhou Minliang, a senior researcher at the Institute of Industrial Economics of the Chinese Academy of Social Sciences, said with the gathering of labor, capital and natural resources in villages, counties and small-sized cities, those places are likely to nurture industries based on their natural resources.

Zhou said an industry boom helps attract downstream industries and thus forms a relatively complete industry cluster, which is important in boosting the local economy. But companies still need to build brands and develop value-added services to move up the global value chain.
