Abstract:

Traditional evaluation of regional competitiveness is usually focused on economic indexes and hardly on ecological factors.However，the ecoenvironment has been converted into a basic condition in rapidly developing regions，ensuring their regional development and playing an increasingly restrictive role in the regional sustainable development.The author put forward the concept of “ecoenvironmental competitiveness” in this case of study on the area along the Yangtze River in Anhui Province.Counties (urban areas) were used as the basic units of evaluation，and an evaluating index system of ecoenvironmental competitivenesss composed of 4 factors—ecoenvironmental pressure，ecoenvironmental status，economic development demand and active coordination ability was built up.The study area was divided into five levels.The regions with high ecoenvironmental competitiveness are mainly located in the mountain areas in the south and west of the area and in Hefei urban area.The regions with low ecoenvironmental competitiveness are mainly in He CountyWuwei Plain，which is a region of traditional agriculture，and in Ma′anshanTongling region of heavy industry.The ecoenvironmental competitiveness not only concerns the quality of the natural ecological system but also is related to the level of technology and economy，the level of investment in and the ability of administration of ecological construction.The ecological problems in different regions and the possible ways for optimization were also discussed.

Key words: ecoenvironmental competitiveness, evaluating indexes system, principal component analysis, the area along the Yangtze River in Anhui Province
