In this study, by carrying on the spot investigation to the seven coal cities in Northeast China and interviewing with the local authority and the residents, the authors definite the vulnerability that is closed to exposure, sensitivity and resilience, and set up vulnerability model of coal cities in Northeast China. At the same time, the authors broadly illustrate how the components of natural-social-economic system act in the coal area, so as to probe the ways to reduce vulnerability more effectively, such as preferential national policy and so on. Furthermore, the article studies the relationship between vulnerability and sustainable development. Vulnerability is a spatio-temporal function of sustainable development. The regional sustainable development refrains the spiral ascending of vulnerability. And the regional vulnerability and sustainable development appear in turn. Then the article analyzes the natural vulnerability, social vulnerability and economic vulnerability of coal cities in Northeast China. At last, combing vulnerability model and situation of coal cities in Northeast China, the authors put forward regional technology innovation mode, multi-dimension structure transformation mode, attracting investment mode and recycling economy mode to reduce vulnerability.
Winning the battle against pollution and strengthening ecological protection in all respects are vital for promoting green development and building a moderately prosperous ecological civilization in China. Using the entropy weight method, this paper establishes and evaluates a comprehensive industrial pollution index that contains and synthesizes six major industrial pollutants (wastewater, COD, waste gas, SO2, NOx, and solid waste) in the 2006–2015 period. Subsequently, this paper studies the spatiotemporal characteristics and influencing factors of industrial pollution via the Moran index and spatial econometric analysis. The empirical results indicate that (1) the temporal evolution of the industrial pollution index is characterized by an overall trend of first decreasing and then increasing. (2) The industrial pollution index of each county has certain geographical disparities and significant spatially polarized characteristics in 2006, 2009, 2012, and 2015. (3) The Moran test shows that there is a relatively significant spatial autocorrelation of the industrial pollution index among counties and that the geographical distribution of the industrial pollution index tends to show clustering. (4) Spatial regression models that incorporate spatial factors better explain the influencing factors of industrial pollution. The economic development level, technological progress, and industrialization are negatively correlated with industrial pollution, while population density and industrial production capacity are positively correlated. (5) Consequently, as relevant policy recommendations, this paper proposes that environmental cooperation linkage mechanisms, environmental protection credit systems, and green technology innovation systems should be established in different geographical locations to achieve the goals of green county construction and sustainable development.
In order to explore the economic-environment harmony development rule, panel data were used to calculate the harmony degrees of each province from 1996. The main results could be summarized as follows: ① As a whole, the harmony degree, which was influenced by economy development distinctly, improved evidently with rising from 0.399 to 0.617, although it had been in a U shape curve since 1996. ②The harmony degree decreased from east to west. Furthermore, the gaps among the three zones were widening. ③ The economy is the main factor to promote harmony development, whose contribution was twice more than environment. Among the economic system, the contribution of development elements to the harmony degree was more than stock elements. ④All limiting factors were from environment system,whereas,their restriction were limited. ⑤There was a very significant negative correlation between the harmony degree and Thiel indices. It was to say that the higher the harmony degree was, the smaller the regional difference was. ⑥ The difference among three zones had most contribution (66.6% ) to the regional difference of harmony development level. And the level in the inner provinces of every zone was relative equilibrium.
Sustainable development is the topic of world research nowadays.Developing eco-economy is an essential way to achieve sustainable development.Jilin province,according to its status quo of society,economy and environment,formulated the developmental strategies for the realization of eco-economic province in 1999,intended to develop eco-economy of the whole province so as to improve Jilin province's competitiveness and realize sustainable development.In China,Jilin province is the second one after Hainan province which put forward the developmental strategies for the accomplishment of eco-economic province. Jilin Province,located in the middle part in Northeast China,is one of the oldest industrial areas,governing 9 districts: Changchun,Jilin,Siping,Liaoyuan,Baishan,Tonghua,Songyuan,Baicheng and Yanbian.Although it had contributed much to the national economic development,yet its previous economic development pattern was only focused on the utilization of resources while neglecting the protection of eco-environment,hence leading to serious deterioration of eco-environment and damage of natural resources.Now the regional competitiveness,with decreasing resources and degraded environment,declined quickly.So in order to improve integrated competitiveness of the whole province,it is quite important to sustain and restore eco-environment and realize sustainable development.Based on the analysis of economic,social and ecological conditions and characteristics,the strategic goals were designated,aiming to improve eco-environment,accelerate economic development,improve competitiveness and realize sustainable development of Jilin Province.It planned to take 30 years to achieve an eco-economic province. This paper explains the connotation of eco-economic and regional competitiveness,and establishes the assessment indexes system and methods,with which to evaluate eco-ecological competitiveness of eco-economic district,including 9 districts.The assessment result shows that the best region is in the middle,and then is the east region,the region between the east and the middle,and the worst is the west region.At last some advices based on the research result are proposed for constructing Jilin eco-economic province.
Improving comprehensive agricultural productivity is an important measure to realize agricultural modernization. Based on the data from Jilin Statistical Yearbook, this study analyzed the spatial and temporal characteristics of comprehensive agricultural productivity discrepancy in the main agricultural production areas of Jilin Province, China. The comprehensive agricultural productivity of 25 county-level administrative units were evaluated by a comprehensive index system based on five aspects which included 20 indicators from 2004 to 2017. The pattern of the discrepancy was analyzed by the spatial differentiation indices and spatial convergence theory. The results were as follows: 1) the overall comprehensive agricultural productivity was in a ‘W-type’ rising trend; 2) the discrepancy was in ‘inverted W-type’ trend; 3) the spatial distribution characteristics were mainly discrete plaque and ‘inverted V-type’; 4) the formation of differences was forced by a combination of internal and external driving forces. Our study demonstrates the effectiveness of rising agricultural productivity and the level of economic and social developments in different counties in Jilin Province.
