[Industrial ecological development of Jilin Province, Northeast China based on structure optimization vision.] / 基于结构调整视角的吉林省产业生态化发展.

Based on the interactive coercing mechanism between the industrial system and the ecosystem, we evaluated Jilin's ecologicalization of industrial structure, employing the systematic ana-lysis method and the comprehensive index evaluation method, and explored the spatio-temporal cha-racteristics.The result showed that the ecological level of industrial structure as well as the industrial structure optimization and resource-environmental efficiency had been significantly improved in 2000-2013. The regional difference showed a trend of resource-environmental efficiency > industrial structure optimization > ecologicalization of industrial structure. Spatially, it demonstrated a "higher in west, lower in east" pattern, and at city scale, it showed a decreasing trend from the core (Changchun) to outside. According to the coordination of industrial structure optimization and resource-environmental efficiency, we categorized the nine cities in Jilin Province into four ecologica-lization types: high coordination type, low coordination type, economic development ahead, and ecological development ahead.

[Dynamic coupling and spatial disparity of economic development and water environmental quality in Songhua River Basin of Jilin Province, Northeast China].

By using coupling model, this paper analyzed the relationships between the economic development and water environment quality in Songhua River Basin of Jilin Province from 1991 to 2010. During the study period, both the economic development index and the water environment index in the Basin showed an uptrend, basically in a coordination state. From the perspective of coupling coordination degree, the economic development and the water environment system were in interactive coupling, with the features of complexity, nonlinearity, and time-variation. As a whole, the coupling experienced three stages, i.e., low level stage, antagonistic stage, and breaking-in stage. As for the coupling degree, the coupling of the economic development and the water environment system was in the first quadrant, i.e., at a development stage of basic coordination. From the perspective of spatial disparity, the coupling degree of the economic development and the water environment system was higher in the upper reaches of the Songhua River Basin, including Changchun and Jilin, than in the lower reaches, including Songyuan and Baicheng. The coupling degree was not only significantly positively correlated with regional economic development, but also affected by the links between the regions as well as the industrial structure within the regions. The economic development of the cities in the upper reaches of the Songhua River Basin was obviously higher than that in the lower reaches, and, due to the adopting of more strict and effective measures for environmental protection and pollution emissions reduction, the water environment quality in the upper reaches of the Songhua River Basin was better.

[Coordinated evolvement of dynamic coupling between economic and environmental systems in Shenyang Metropolitan area].

By using coupling coordinated degree model, scissors difference methods, and coupling degree model, this paper analyzed the coupling coordinated status, development speed difference, and coupling development trend between economic and environmental systems in Shenyang Metropolitan Area in 1990-2009. In the study period, the coupling level of the relations between economic and environmental development was ascending, with the coupling degree increased from 0.42 to 0.89, which reflected the more and more harmonious relationships between economy and environment. The decrease of economic development speed and the increase of environmental construction speed reduced the scissor difference of the two systems from 0.63 degrees to 0.22 degrees, demonstrating the contribution of the economic development speed to the coupling coordinated status. The coupling degree between the economic and environmental systems stretched across in a [45 degrees, 90 degrees] region, which meant that the two systems were in a co-developing status. As the discrepancy between the development speeds of the two systems became smaller, the coupling degree was closer to 45 degrees, and the two systems were becoming better coordinated.

[Shift-share analysis on regional industrial pollution growth].

Based on the statistical calculation of industrial pollution charge, an extended shift share analysis method was employed to study the regional industrial pollution growth in Jilin Province, and the preferred action for regional industrial ecological transition was discussed from a view point of pollution treatment. The results could be summarized as follows: 1) Proportional shift could suggest some ways to promote industrial ecological transition from the aspect of industrial organization, while differential shift can provide some enlightenment for pollution treatment in terms of technology. The variation coefficients of proportional shift and differential shift at regional scale are 15.78 and 34.05 respectively, and the difference between them implies that production technology plays a much more important role than that of industrial organization in the course of regional industrial ecological transition. 2) Comparing the corresponding components at regional scale and neighborhood scale is meaningful to discover the area which has a dominant effect on regional pollution. As to Jilin Province, it should pay more attention on the pollution reducing in Changchun City and Jilin City. 3) By means of identifying sectoral linkage influence and non-linkage influence on pollutants output, regional pollution types can be grouped into compound category and monomial category, and relevant countermeasures could be adopted to control industrial pollution through industrial organization. 4) The spatial structure of industrial ecological transition in Jilin Province can be divided into four regions which are central area, southeast area, western area and eastern area.

[Factor decomposition and reduction effect on the changes of industrial wastewater discharge].

After describing the volume of industrial wastewater discharge, economic growth, economic space structure and industrial wastewater discharge intensity, the non-residue complete decomposition model was applied to analyze the effects of three economically factors, which were economic scale, discharge intensity and space structure, on the changes of industrial wastewater discharge quantitatively from 1981 to 2006 in China. Then industrial wastewater reduction effect was computed by use of H-P filter method. The main results could be summarized as follows: (1) The average annual growth of industrial wastewater discharge is 0.25 x 10(8) t, and the scale of economic development, the space structure and the industrial wastewater discharge intensity have different contributions to the change, being 25.9 x 10(8) t, - 25.5 x 10(8) t, -0.16 x 10(8) t respectively. (2) Accumulative quantity of industrial wastewater discharge reduction is 641.8 x 10(8) t from 1981 to 2006 in China. During this period, with the impact of macroeconomic policies, reduction gap has been fluctuating; however, total reduction gap is a positive number. It is to say that actual reduction volume is more than potential reduction one. (3) With the shift of time, potential reduction efficiency tends to increase firstly and then decline. (4) During 1982-1990 and 1997-2006, industry is high-pollution, while during 1991-1996, industry is low-pollution correspondingly.
