Green trends drive tech boom

Emerging and high-tech industries are prospering as the world progresses toward a greener economy, and Central China's Hunan province is no exception.

Last year, Hunan experienced a crucial period of development for its strategic emerging industries like alternative energy, new materials and high-end equipment manufacturing. The revenue of these industries increased by 31 percent year-on-year.

In addition, the number of companies involved in new and advanced technology has grown in this favorable environment, and they now account for 33 percent of all companies with an annual income of more than 20 million yuan ($3.2 million).
