3.3. Exogenous parameters in the model
When setting the exogenous parameters, we reference government plans including the comprehensive work plan for ABT199 conservation and emission reduction during the Twelfth Five-Year Plan period ( State Council, 2011a) and the Twelfth Five-Year Plan for the national economic and social development of Beijing ( Beijing Municipal Commission of Developement and Reform, 2011). Table 2 shows the settings of all exogenous parameters in the model.
4. Result analysis and discussions
Based on the optimization model, the adjusted structures of Beijing with the five objectives in 2020 are obtained. In addition, the initial industrial structure in 2010 is chosen as baseline as usual (BAU). In BAU scenario, geological time is supposed that the GDP is the same as Objective 1 (maximization of GDP). Fig. 4 shows the results of adjusted structures and initial structure in 2020 in Beijing.

Energy intensity and carbon intensity are measured by right coordinate axis.)Figure optionsDownload full-size imageDownload as PowerPoint slide
