以产业演进推动进城农民工就业转型和稳态城镇化

稳态式城镇化需要协同推进进城农民工就业转型与产业结构优化升级。研究发现,产业演进、农民工就业转型和城镇化稳态之间存在协同统一性,产业升级不会必然造成农民工失业。协同推进进城农民工就业转型与产业结构优化升级需要构建基于主体间不完全信息动态博弈的DLM治理机制,即以大数据统计分析为基础的科学决策机制、以利益公平分配为导向的动力机制、以交互影响为主体的动态学习机制。为提高协同治理成效,应加快科技成果产业化,开展前置性技能培训,完善城市经营管理体系和农民工工资发放制度再设计等。

The Empirical Analysis on the Dynamic Effect of Rural-urban Migration on the Consumption Growth of Residents in China——Based on Varying Parameter State-space Model

The research constructed varying parameter state-space model and per- formed estimation on dynamic relationship between urban-rural migration and aggre- gate consumption expenditure on basis of dual economic structure. The results showed that urban consumption growth made the most contribution to aggregate consumption growth, followed by urban-rural migration caused consumption. The role of rural consumption growth kept stable, but consumption caused by population growth was decreasing. Therefore, China consumption growth mainly relies on urban consumption expenditure and urban-rural migration.

Planning and Designing of Small Towns in Underdeveloped Areas from Perspective of Ecocivilization——A Case Study of Shuinan Town,Jishui County,Jiangxi Province

Small towns are important carriers of rural economy development, and center promoting rural advancement in a specific region. However, many environ- mental problems are emerging with rapid urbanization and expansion of small town scale. The research analyzed existing problems of small town planning and con- struction domestically in the context of the 18th Party Congress and proposed coun- termeasures in terms of scale prediction, intensive use of lands, ＂pastoral＂ land- scape pattern, protection and up-gradation of human ecology with a case study of Shuinan Town, Jishui County, Jiangxi Province.

Development of the eco-community planning studies under the concept of low-carbon

Universality of low-carbon eco- city planning measures, Government regulation, as an important planning means to guide urban development urban; it is an allocation mechanism for land and space resource. Low-carbon eco- city planning is especially important for China as it is in a state of rapid economic growth, urbanization acceleration, carbon emissions increase, ecological environment deterioration and intensifying economic transformation. During the process of low-carbon eco-city planning, we must consider the whole range of temporal and spatial distribution of the city and grasp the overall coordination system of time and space. We should regard it as a system of the entire biosphere and regulate urban according to true features of ecosystems, that is in a basically a three-dimensional, integrative compound patterns. We need consider the natural ecological system factors, technological physics factors, economic assets factors, social and cultural factors as well as various humanitarian factors among the urban system structure; consider the impact of the internal and external urban environmental systems; make them interact and influence each other and restrict each other through the planning of the urban system material flow, energy flow, information flow and capital flow; insists the evaluation basic of the healthy development of urbanization and the of exercise macro -control on the dynamic representation＂ of the city development, the ＂qualityrepresentatiou＂ ofthecity＇ s connotation and the air representation＂ of the city state in order to overcome the ＂ urban disease ＂ by development, to reduce the ＂ urban disease ＂ by planning, to treat the ＂ urban disease ＂ by management. Only by bringing the design and control into the scope of long-term planning and governing can we effectively monitor and guide the development and construction of low-carbon eco- towns.

Analysis of Urban Morphology in Core Towns＇ Neighborhoods of Mexico： Santa Barbara＇s Neighborhood as a Case Study

Cities＇ urban morphology is the result of historic, cultural, political and social processes. The historical cores in Mexican cities have high cultural diversity, which also intermingle pre-Hispanic cultures with colonial forms, as well with modernity and post-modernity irruption. The case study is Santa Barbara＇s neighborhood in Toluca City, which was founded in 1524, and the case study was the first neighborhood in Toluca＇s historical core. At present time, this neighborhood is considered as one of the most dangerous places in the city＇s historical core, therefore, it has been abandoned. This paper will display the changes in urban morphology of the neighborhood through the years from 1877 to 2010. For site evaluation, the methodologies of Ashihara （1982） and Lynch＇s （1961） were used in order to analyze positive and negative spaces, as well as main street visual features, street and avenue directions, street circulation and street circulation path configuration. The results show that the focal nodes are a key factor for economic and social reactivation, with which, through urban activation of vacant lots and the traditional use of the streets as public space, is possible to generate centripetal development to restructure the neighborhood.

Relationship between Industrialization, Urbanization and Industrial Ecology in Western China: A Panel Vector Auto-Regression Model Analysis

As the foundation of modern economic development, industry is the engine of industrialized and urbanized development. Industrial ecology is a high-level form of industry that is achieved after it has reached a certain stage, which guides the coordinated industrial development balancing mankind and nature. The implementation of industrial ecology is an important method and effective approach to realize the sustainable development of industrialization and urbanization. In this article, based on the inter-provincial panel data of western China during 2003-2018, the spatial development trends of industrialization, urbanization and industrial ecology are analyzed, and an empirical method is employed to conduct a robustness test based on the Panel Vector Auto-Regression(PVAR) model to determine the long-term interactions among these three aspects. The results show that it is difficult to manifest the short-term causal relationships among industrialization, urbanization and industrial ecology. After lagging for three periods, they present the Granger causality, the industrial ecology and industrialization have promoted urbanization, and the coefficient for the influence of industrial ecology on urbanization is 0.4612. However, industrialization and urbanization have negative impacts on industrial ecology, and with a 1% increase in industrialization or urbanization, the industrial ecology will decline by 0.2261% or 0.2850%, respectively. With the continuation of the lagging period, industrial ecology will have better interpretability than industrialization and urbanization, and industrialization and eco-friendly development have strong self-accumulation development mechanisms, while the self-accumulation mechanism of urbanization is not obvious, and it might even have a decline. By fulfilling the role of the regional leading industry, the state of unbalanced internal development can be improved, so as to realize mutual promotion between industrialization and urbanization. By improving the utilization rates of resources and energy, efforts should be made to implement green production, significantly promote industrial ecology, and boost high-quality development of both the regional economy and society.

Analysis of emergy-based metabolic efficiency and environmental pressure on the local coupling and telecoupling between urbanization and the eco-environment in the Beijing-Tianjin-Hebei urban agglomeration

We use emergy-based urban metabolism analysis in this study to investigate the local coupling and telecoupling between urbanization and the eco-environment in the Beijing-Tianjin-Hebei urban agglomeration. Our analysis encompasses the last 35 years spanning the period between 1980 and 2014. In addition, we analyze urban metabolic efficiency and environmental pressure in these couplings. There are three main conclusions of this study. First, we show that the total metabolic emergy value of the Beijing-Tianjin-Hebei urban agglomeration has increased over the last 35 years, and that external elements have replaced internal ones as the leading contributors to urban metabolism in this region. The proportion of metabolic emergy derived from external elements increased from 30.87% in 1980 to 67.43% in 2014. The emergy extroversion ratio has continued to increase over our study period, while the development of this urban agglomeration had become progressively and more heavily reliant on external elements. Second, over the study period, the metabolic emergy intensity of elements of local coupling and telecoupling in the Beijing-Tianjin-Hebei urban agglomeration has declined at an accelerating rate, from 1.15×10^(21) Sej/100 million RMB in1980 to 9.69×10^(19) Sej/100 million RMB in 2014. This reflects a continuous increase in the economic efficiency of this area.Correspondingly, emergy use per capita increased from 7.8×10^(15) Sej/person in 1980 to 5.83×10^(16) Sej/person in 2014, suggesting a gradual rise in the level of social welfare in this urban agglomeration. However, we also observed a consistently elevated environmental loading ratio(ELR) in our analysis in terms of metabolism of local coupling and telecoupling elements. This result indicates that environmental pressure has also increased constantly within the Beijing-Tianjin-Hebei urban agglomeration. Third,our analysis shows that the ELR of metabolic emergy from internal elements increased from 8.30 in 1980 to 43.46 in 2014, while the ratio from external elements increased from 4.15 to 92.03. Thus, we quantitatively investigated the dependency of development within this urban agglomeration on external elements as well as the resultant environmental load. The conclusions of this study provide the basis for quantitative policy-making in the Beijing-Tianjin-Hebei region, optimizing economic structures, improving economic efficiency, controlling environmental pollution, and promoting the coordinated development of this region.
