BEIJING -- The annual forum marking the release of the latest TOP 500 Enterprises list in China is now under way in the southwestern city of Kunming.

The event's importance lies in the platform it has created for entrepreneurs to communicate under the current process of transformation to try to seize the pulse of China's economic activity.

CRI's Hu Jia is at the event, telling you more about what concerns and spurs on Chinese business leaders.

This year the summit is being held under the theme: "Branding and Leadership: Developments of China's Large Enterprises amid Economic Upgrading" at a time when China is facing a less welcoming external trade environment and increased internal restructuring pressures.

"For large enterprises here in China, if they have to name their main concern now, it is that they feel uncertain about the future and the economic situation, whether the weakness will continue and how long it will last."

That's Hao Yufeng, director of the research department at the China Enterprise Confederation. He says the rational growth expectation of China's economy has forced domestic firms to drop the approach of seeking extensive profits as they try to find a more sustainable business model.

"I'm interested in the forum on Green innovation driving the evolution of the industry."

That's Ji Rusheng, deputy chief engineer and director of Economic Operation Division of China Pingmei Shenma Group, one of the largest producers of coking coal and thermal coal in the country.

He says that the "Green innovation drives the evolution of the industry" forum is what he's looking into and the topic exactly tackles the needs of the company.

"We should practice green awareness after we finish the initial phase of prioritizing the accumulation of resources. We need to protect the mining ground the moment we start excavating. In the short term, the company will need to spend more investing in this, but it benefits the company in the long-term, even with regard to the brand's image and reputation."

However, export-oriented companies may disagree as to whether it is too early to discuss green innovation when difficulties still exist for shipping our traditional export products.
