Spatiotemporal Characteristics of Rural Labor Migration in China: Evidence from the Migration Stability under New-type Urbanization

Although the factors affecting rural-to-urban migration have been discussed and analyzed in detail, few studies have examined the spatiotemporal dynamic characteristics of rural migrants’ employment and working-cities in the post-immigrate era, which is essential for the citizenization and social integration of new-type urbanization in China. This study uses survey data from rural migration laborers across the eastern, central, and western China to construct a comprehensive labor migration stability index, and compares the determinants of the migration stability of rural labor among cities and industries using Geodetector. The results are as follows: 1) Compared with the midwestern cities, eastern cities have attracted younger and more skilled rural labor, and industries with higher technical content have higher migration stability among rural laborers. 2) Rural laborers more often adapt to changes by changing employment instead of changing working-cities. 3) The individual experiences of rural laborers and urban characteristics have significant impacts on the stability of migration, and family and societal guanxi(Chinese interpersonal relationships) enhance migration stability. 4) A unified labor market and convenient transportation have somewhat slowed industrial transfers and labor backflow. This study enhances our understanding of the roles of industrial transfer and new-type urbanization in shaping the labor geography landscape and provides policy implications for the promotion of people-oriented urbanization.

Paleoenvironments Recorded in a New-Type Ferromanganese Crust fromthe East Philippine Sea

We attempt to recover the paleocnvironments recorded in the accretion of a typical newtype hydrogenetic ferromanganese crust from the deep water areas of the East Philippine Sea. From detailed geochemical and U-series chronological studies, analysis of major and minor elements performed by X-ray fluorescence spectrometry （XRF） and inductively coupled plasma-mass spectrometer （ICPMS）, three major accretion periods and corresponding paleocnvironments can be ascertained. The first period is a faster accretion period in the terminal Late Miocene to the Early Pliocene with looser structure and higher volcanic detritus content, corresponding to the active Antarctic bottom waters and depressed temperature from the intermediate Middle Miocene to the Early Pliocene. The second period is a pulse of pelagic clay deposition at the Early to Middle Pliocene, reflecting the shrinkage of the Antarctic bottom waters and the global temperature elevation of this period. The third period is a slower accretion period from the Middle Pliocene, which indicates the more violent activity of Antarctic bottom waters once again and more depressed temperature than the first period, facilitating the accretion of a more compact and pure ferromanganese zone. The paleoceanographic histories of these studied areas had not been made clear in previous research.

Dynamic changes and driving factors of land use under new-type urbanization: A case of Guiyang

With the continuous progress of new-type urbanization in Karst mountain area, how to correctly deal with the relationship between urban economy and land use are attracting much attention. Based on the land-use change data, this paper analyzes the characteristics of land use change and its driving factors in Guiyang with the method of land-use dynamic analysis, land utilization and factor correlation analysis. We get the following results:(1) the change of land use was obvious during 2004 and 2012. The area of arable land and other land were decreased, the rate of decrease are 3.89% and 8.24%. In the meantime, a series of construction land and forest area increased a lot, the rate of increase are 3.89% and 8.24%.(2) The integrated land use dynamic degree of two research stages(2004-2009 and 2009-2012) were decreased from 2.12% to 0.34%, this suggests dynamic changes of land tend to be stable.(3) Four kinds of Land use class have a great contribution to the index of land use degree respectively. The composite index of land use degree rose from 229.58 to 247.19 during 2004 and 2012; the land use is still in the development stage.(4) Economy, population, transportation and policy guidance are the main drivers of land use change.

Numerical calculation of flow and heat transfer process in the new-type external combustion swirl-flowing hot stove

It is clarified that the important method to improve the blast temperature ofthe small and the middle blast furnaces whose production is about two-thirds of total sum of Chinafrom 1000℃ to 1250-1300℃ is to preheat both their combustion-supporting air and coal gas. The airtemperature of blast furnaces can be reached to 1250-1300℃ by burning single blast furnace coal gasif high speed burner is applied to blast furnaces and new-type external combustion swirl-flowinghot stove is used to preheat their combustion-supporting air. The computational results of the flowand heat transfer processions in the hot stove prove that the surface of the bed of the thermalstorage balls there have not eccentric flow and the flow field and temperature field distribution iseven. The computational results of the blast temperature distribution are similar to thosedetermination experiment data. The numerical results also provide references for developing anddesigning the new-type external combustion swirl-flowing hot stoves.

Global energy transition revolution and the connotation and pathway of the green and intelligent energy system

The essence of energy system transition is the"energy revolution':The development of the"resource-dominated"energy system with fossil energy as the mainstay has promoted human progress,but it has also triggered energy crisis and ecological environment crisis,which is not compatible with the new demands of the new round of scientific and technological revolution,industrial transformation,and sustainable human development.It is in urgent need to research and develop a new-type energy system in the context of carbon neutrality.In the framework of"technique-dominated"new green and intelligent energy system with"three new"of new energy,new power and new energy storage as the mainstay,the"super energy basin"concepts with the Ordos Basin,Nw China as a representative will reshape the concept and model of future energy exploration and development.In view of the"six inequalities"in global energy and the resource conditions of"abundant coal,insufficient oil and gas and infinite new energy"in China,it is suggested to deeply boost"China energy revolution',sticking to the six principles of independent energy production,green energy supply,secure energy reserve,efficient energy consumption,intelligent energy management,economical energy cost;enhance"energy scientific and technological innovation"by implementing technique-dominated"four major science and technology innovation projects',namely,clean coal project,oil production stabilization and gas production increasing project,new energy acceleration project,and green-intelligent energy project;implement"energy transition"by accelerating the green-dominated"four-modernization development',namely,fossil energy cleaning,large-scale new energy,coordinated centralized energy distribution,intelligent multi-energy management,so as to promote the exchange of two 80%s"in China's energy structure and construct the new green and intelligent energy system.

New-type urbanization in China： Predicted trends and investment demand for 2015-2030

The future development of new-type urbanization has drawn great attention from both the government and public alike. In this context, the present study had three related research aims. Firstly, it sought to predict the urbanization and population dynamics in China at both national and provincial levels for the period of 2015 to 2030. Secondly, on this basis, it sought to examine the spatial variation of urbanization given the predicted national urbaniza- tion rate of 70.12%. Thirdly, it sought to estimate and evaluate the national and provincial demands of investment in the development of new-type urbanization. The main conclusions from this study were as follows： （1） The population size and urbanization rate will reach 1.445 billion and 70.12%, respectively, from 2015 to 2030. （2） The demographic dividend will vanish when the population pressure reaches its maximum. During this period, there will be 70.16 million urban population born. The suburban population that becomes urbanized will be 316.7 million, and thus the net increase in urban population will reach 386 million. （3） Although the urbanization rate of every Chinese province will increase during 2015-2030, it will do so un- equally, while differences in urbanization quality among provinces will also be substantial. In some provinces, moreover, the urbanization quality is not compatible with their eco-social development. （4）A total of 4,105,380 billion yuan is required to fund new-type urbanization and the investment demand for each province varies greatly; for example, Guangdong prov- ince requires the most funding, amounting to approximately 148 times that required by Tibet, the province in least need of funding. In the final part of this study, policy suggestions con- cerning the investment of the new-type urbanization are put forward and discussed.

Paleoenvironment evolution of the East Philippine Sea recorded in the new-type ferromanganese crust since the terminal Late Miocene

From systemic research of microstructure, geochemistry, uranium-series and 10Be isotope dating on a new-type deepwater ferromanganese crust from the East Philippine Sea, the paleoenvironment evolu-tion of the target area since the terminal Late Miocene was recovered. The vertical section changes of microstructure and chemical composition are consistent in the studied crust, which indicate three major accretion periods and corresponding paleoenvironment evolution of the crust. The bottom crust zone was formed in the terminal Late Miocene (5.6 Ma) with loose microstructure, high detritus content and high growth rate. Reductions of mineral element content, accretion rate and positive Ce-anomaly degree at 4.6 Ma indicate temporal warming, which went against the crust accretion and finally formed an accretion gap in the terminal Middle Pliocene (2.8―2.7 Ma). The more active Antarctic bottom sea-waters in the Late Pliocene (2.7 Ma) facilitated the fast transfer to the top pure crust zone. Hereafter, with the further apart of volcanic source and the keeping increase of eolian material (1.0 Ma), although surrounding conditions were still favorable, mineral element content still shows an obvious reducing trend. It thereby offers new carrier and data for the unclear paleoceanographic research of the target area since the terminal Late Miocene.

Supply modes for renewable-based distributed energy systems and their applications:case studies in China

Distributed energy systems(DES),as an integrated energy system with coupled distributed energy resources,have great potential in reducing carbon dioxide emissions and improving energy efficiencies.Considering the background of urbanization and the energy revolution in China,the study investigates the renewable-based DESs supply modes and their application in China.A new method is proposed to classify DESs supply modes into three categories considering the renewable resource in domination,and their application domains are discussed.A comprehensive model is given for economic and environmental evaluation.Typical case studies show that the renewable-based DES systems can supply the energy in a cost-effective and environment-friendly way.Among them,the biomass waste dominated supply mode can not only achieve"zero"carbon emissions but also"zero"energy consumption,even though not yet economically attractive under the present policy and market conditions.Thus,recommendations are given to promote the further deployment of renewable-based DESs,regarding their supply modes,policy requirements,and issues to be addressed.

Research on Financial Support for the New Types of Agricultural Management Entities from the Perspective of the Rural Revitalization Strategy

Both the escape from the predicament of traditional financial support in rural areas and the cultivation of new types of agricultural management entities underlie,at a micro level,the improvement of a new-type of agricultural management system,and offer an important guarantee for the implementation of a rural revitalization strategy.In reference to the demands of carrying out reform,activating factors,invigorating entities and stimulating markets during the implementation of this rural revitalization strategy,we are applying a financing preference theory that infers and analyzes the excessive preference for new-type agricultural management entities(family farms,specialized farmer cooperatives,specialized large family farms,and modern agricultural enterprises)regarding government subsidies(quasi-equity financing).Our analysis has identified crucial factors in the issue and predicts that government subsidies(quasi-equity financing)will crowd out financial support funding(quasi-debt financing),and we offer empirical proof obtained through statistical modeling.As our results indicate,financing costs,free cash flows,and the perceived income adequacy(PIA)of new-type agricultural management entities all have significant influence upon decision-making for debt financing by such entities.Therefore,with the concrete contents of the formulation of policies concerning the financial support for rural agricultural strategy,one not only needs to consider the further decrease of financing costs,but also should take into account both the designing of cash flow mechanism in the process of paying both principal and interest,and the improvement of bankruptcy rules for agricultural management entities to accelerate the transformation of family farms,specialized farmer cooperatives,and specialized large family farms,towards modern agricultural enterprises.Meanwhile,upgrades to the supply chains of the agriculture industry,improvements to the construction of the rural financial information system,building an accounting system that meets the requirements of the rural revitalization strategy,and giving full play to the policies for financial support,which assume an important role in activating factors and markets during the implementation of the rural revitalization strategy,are also anticipated.

Research on challenges and strategies for China's green economy development

The last 20 years have been the fastest economic developing period of China,and China has made great economic achievements through undertaking international industrial transfer.However,undertaking international industrial transfer has brought about severe environmental problems to China and the process of undertaking international industry transfer is also a process of undertaking international transfer of natural resource consumption and environmental pollution.Nowadays,China has the heaviest ecological burden and highest environmental risk in the world,and is gradually losing international competitive advantages among traditional industries.China is facing unprecedented pressure of economic transformation.Besides the advantages like huge domestic demands and abundant civil capital,China faces more challenges in its green economy development.First,China is still in the middle of industrialization and urbanization processes,hence the huge demands for traditional industries will only last 10-15 more years.Meanwhile,China lacks core technologies for transforming traditional industries,which means these industries will have high shut-down risks.Second,the domestic market share for new green industries is limited,since the market is dominated by traditional energy industries.Third,the value of land,water,mineral,and other natural resources is extremely underestimated because the environmental cost is excluded from the enterprises'cost-benefit calculation.China should foster and expand green industries based on domestic demands,and then strive for competitive advantages in the international market in the future.Therefore,China should focus on the following four points in order to promote green industry development:establishing a forced-upgrading-mechanism for traditional industries,an incentive-development-mechanism for new green industries and a TFP-based(total factor productivity based)economic development evaluation system;promoting the integration of new-type urbanization,new emerging industries,and new employments;taking the model of"technology innovating-patent formulating-standard establishing-market guiding"to enhance the global competitiveness of China's new emerging industries;and building green consumption patterns in the whole society.

A bi-level optimal scheduling model for new-type power systems integrating large-scale renewable energy

The construction of a new type of power system is a key way to achieve the goal of‘carbon peaking and carbon neutrality’.In the process of developing renewable energy,large-scale wind and photovoltaic power systems replace conventional units,which will have an impact on the stability of the power grid.To eliminate these concerns,this paper proposes a bi-level optimal scheduling model for new-type power systems.The upper level aims to minimize fluctuation of net load,with the consideration of demand response,to smooth the load curve.The lower level takes the minimum operating cost of the new-type power system as the objective function and the most economical scheduling strategy is established.To deal with the uncertainty of renewable energy integrated within the system,the lower model is transformed into a two-stage robust optimization model and solved by applying a column-and-constraint generation method.Finally,a regional power system is selected to conduct a case study comprising 760 MW thermal power,50 MW·h energy storage,200 MW wind turbine and 150 MW photovoltaic power.The results show that the constructed two-stage robust optimization model is conducive to establishing the most economical scheduling scheme of the system with an uncertain budget and the minimum operation cost is$45,9031.In addition,demand response and energy storage can reduce peak-to-valley differences in the power system.
