Strategic Study on Integration of Port and City Development in Rizhao

agglomeration of the Yangtze Delta （UAYD）, one of the most developed regions of China, has witnessed an increasing prevalence in building ecological cities when the ecological cities are pursued by many modern cities, and great achievements have been made in this regard. It is inevitable, however, that certain problems exist during the construction of ecological city, which include but not limited to non-harmonious development of urban complex ecosystem, and the difficulty in quantifying eco-city construction or incomplete quantification in assessing the con- structiori of present and future eco-city. Based on the analysis on social-economic conditions and regional conditions of the UAYD, this paper attempts to set up an index system of eco-cities combining with local characteristics, and to adopt the indices of eco-city, urban harmony, and eco-city colligate to evaluate the ecological level, urban harmonious development and eco-city construction of cities within the UAYD. Results indicate that among 15 cities in UAYD, Suzhou City ranks the highest in terms of eco-city construction, whereas Nantong ranks relatively lower; sustainable eco-city construction is possible only when cities are developed in every respect of harmony.     

Employment and structural impacts of material efficiency strategies: results from five case studies

In order to come up with a sound assessment of the effects of material efficiency innovations on growth, employment and competitiveness, different economic mechanisms have to be considered. From a methodological point of view, the analysis must be able to account for technology specific aspects. The employment impacts of five innovations are analyzed: plastic and paper recycling, increased life span of automobiles, car sharing, and bio-based products. Time horizons for all strategies are scenarios until 2020.The economic impacts are context specific with regard to innovation, technology and country. The economic impacts highlight substantial structural adjustments. The overall economic net impact on employment tends to be neutral to positive. Stronger positive economic impacts result if first mover advantages can be established.
