  32. 32. Changing relationship between city and periphery New strategies of economic development for Beijing suburban areas 1) High and New Technologies will be actively promoted through structural adjustment of the second industry sector: electronic communication, new materials, ecological engineering, new medication and so on. 2) The third industry sector of suburban area will be developed, with emphasis on fostering new types of services: cultural heritages and natural sights, landscape, production process and village culture, tourism integrated with restaurants, hotels, recreation and shopping as a industrial system. 3) Urbanization of countryside independent from the central urban area will be considered as an alternative way of urban growth. Satellite towns are the future economic centralities to be promoted, to partake urban functions like science and technology, education, culture, logistics and so on.
