YULIN, China, Aug 22 (Reuters) - At the section of the Great Wall of China that runs through Yulin, tour guide Gao Jing says she tried to learn English in expectation of the increased number of overseas visitors the city planned to attract as part of its economic transformation.

But the international tourists haven't come to Yulin, once a coal, oil and natural gas boom town in the northwestern province of Shaanxi, and in their absence she has forgotten her English.

"Sure, there's lots of talk about developing our tourism industry but walking the talk is a different matter," said Gao, who's been a tour guide there for 10 years.

"There's an immediate return on investment if you invest in energy. But you may need to wait 10, or even 100 years, if you want to see a return on investment in tourism."

The experience of Yulin carries a lesson for other Chinese cities trying to re-tool their economies - establishing a vibrant services sector takes time, and in the meantime you cannot afford to abandon your industrial strengths.

As its economy matures, China is trying to steer away from the export and investment-led model that fuelled its dizzy rise towards a more sustainable base built on domestic consumption.

Yulin has been a poster child for that attempt to move up the value chain, singled out by the national media as an example of economic transformation worthy of study by other regions.

Aside from gushing news articles about Yulin's success in diversifying its economy away from natural resources, the provincial government is notable for releasing a 27-step plan in 2013 about how this economic transformation should occur.

But since then things have not gone precisely to plan.

A slowing economy has dragged down industries such as tourism and renewable energy, handpicked by the provincial government as new drivers of Yulin's economy.

"At the peak of the coal boom we were already thinking about how to transform our economy, move it up the value chain, but it hasn't been the success we'd hoped it would be," said Zhang Changqing, Yulin investment bureau's party secretary.

GROWTH LESSONS

The goal was for Yulin to shift into services, move away from an economy dominated by state-owned enterprises (SOE) towards one with private businesses at its core, and produce higher value coal, oil and natural gas.
