Shenzhen, a southern coastal city neighboring Hong Kong, marked its 30th anniversary as China's first economic reform zone Monday.

Chinese President Hu Jintao told a celebratory rally held in Shenzhen Monday morning the central government will always support the country's special economic zones (SEZ) embarking on "brave exploration" in their roles as "first movers."

"The SEZs will not only continue, but should work better," Hu said. Xiamen, Shantou, Zhuhai and Hainan are the country's other SEZs.

Hu, also general secretary of the Communist Party of China (CPC) Central Committee, said the Shenzhen SEZ has been the scene of miracles in industrialization, urbanization and modernization.

He said the SEZ has made important contributions to the country's reform and opening-up.

Once a small fishing village, the Shenzhen SEZ has evolved into a metropolis over the past three decades. It is home to the Shenzhen Stock Exchange as well as headquarters of many high-tech companies.

Hu called on SEZs to become the spearheads in accelerating the transformation of economic growth model, which was a "significant, strategic task concerning the country's overall economic and social development."

A technological innovation system should be built to combine enterprises, market, production and research to enhance innovative capability of core technologies, so as to drive economic development with innovation, Hu said.

He called for accelerating the adjustment of the economic structure and boosting consumption, especially household consumption.

Efforts should be made to develop the advanced manufacturing industry and high-end service industry and seize the commanding position of emerging industries of strategic importance, he said.

The development of urban and rural areas should be well coordinated and the construction of the "new countryside" should be combined with urbanization, with cities playing a leading role, Hu said.

He also called for developing modern agriculture and increasing farmers' income, developing human resources, enhancing energy conservation and environmental protection, promoting low-carbon technologies and developing green economy.
