Improving the cultivated land use ecological efficiency (CLUE) to obtain greater agricultural output at a lower environmental cost, is an important part of effective management resources and sustainable intensification (SI). However, when evaluating CLUE, existing research ignores heterogeneity production environment different units, which leads "distortion effect". To address this, this study focuses on Yangtze River Economic Belt (YREB) in China as area uses three-stage super-efficiency...

Migrant relocation (MR) is an important way to solve social and ecological problems. Current studies have mainly used the sample survey method analyze economic benefits of migrant from a micro perspective but less global impact on cropland abandonment (CA). Therefore, in order balance regional utilization poverty alleviation, this paper aimed MR program (CA) macro scale. The results showed that during 2011–2020, scale resettlement Pingli County were 10.691 km2 4.535 km2, respectively....

Abstract With the importance of sustainable development widely accepted, relationship between natural capital utilization and economic has become a global focus. This study analyzes in countries along China's “Belt Road” initiative using panel regression model. The results show that labor force, rural urban populations, exports imports have significant impact on both consumption development. However, here is contrary to theory experience. We also find there still resource dependence long‐run...

Silica fiber under high pressure increases the risk of breakage or permanent deformation, which may cause sensor failure due to mechanical strength limitations. High can also induce birefringence in optical fiber. In this study, we present a simple design and low-cost using polymer (POF) based on intensity-variation technique. A side-coupling mechanism structure is adopted, varies intensity with applied pressure. Two POFs are twisted together create sensing region where light launched first...

Climate change has gained widespread attention, and the rapid growth of economy in China generated a considerable amount carbon emissions. Zhejiang Province was selected as study area. First, energy-related emissions from 2000 to 2014 were accounted for, then Logarithmic Mean Divisia Index (LMDI) decomposition model applied analyse driving factors underlying Finally, three scenarios (inertia, comparative decoupling absolute decoupling) for 2020 2030 simulated based on low-carbon city Human...

New-type urbanization is a dynamic process composed of numerous elements and multiple subsystems. Coordination coherence various subsystems are critical for promoting urban-rural integration regional synergistic development will have complicated impact on sustainable in the trade-off between socioeconomic growth environmental conservation. This paper theorized interconnected mutually influential coupling coordination relationship population-land-economic (PLEU) mechanism by which this...

Metrorail accessibility is an important indicator that influences urban spatial form. For this article, we created a 3SFCA method to analyze the of Shanghai covering four levels: traffic analysis zones (TAZs), stations, metrorail network, and regions. The floor area ratio (FAR) was used reflect form, coordination model introduced examine balance between forms. Results revealed distribution form are characterized by monocentric structure, while values both variables decrease gradually from...

Internal migration in China has resulted large numbers of left-behind children. Despite growing attention paid to this population, existing research not systematically addressed the mediating mechanisms linking parental children's health. The present study examines influences on health children and channels, using data from a new nationally representative survey. We compare three groups rural aged 3–15 years ( N = 2473): those who were left behind by both parents, one parent living with...

Summary The results of this analysis show that, while the mechanism forgaining opportunities to access higher education is complex, thebasic thread that runs through it can be clearly seen: Though dif-ferences in nature among various types educationhave determined for them are governed by dif-ferent models, scarcity such social and thediffering effects social-class background status wereclearly present throughout 1978–2003 period, while, at sametime, different senior high level...

Although local government has played an important role in rural China’s development, some disadvantages of government-led construction have gradually emerged with changes socioeconomic structure, which negative impacts on development. To solve the problems traditional pattern, introduction market mechanisms into became consensus theory and practice. Extant studies emphasize importance a market-driven pattern; however, they do not discuss how to practice this pattern detail. Thus, paper uses...

Individual education performance is usually influenced jointly by ability and background (family background). The relative share of these two factors forms the basic grounds for judgments educational equity. Using sheaf coefficients, we compare influence mechanisms on distribution access to regular first degree higher opportunities institutions at different levels. Our findings show that both family have a marked influence. level institution, greater demanded its students. effect also...

Abstract With the data from 2003 National General Social Survey (GSS2003), present article focuses on discussing consequences and influences of objective stratum positions in related social fields urban China. Residential space, interaction, lifestyle, identification constitute four dimensions analysis. The basic conclusion is: residence, identification, especially both ends structure, stratification is primary trend, whereas trend dimension lifestyle rather unclear. Lack correspondence...

Abstract In previous studies on social stratification and mobility in China, education is considered as the core mediatory factor reproduction mobility. This paper, however, investigates how childhood health affects stratification. Using data from Urbanization Labor Migrant National Survey (2012), this study examines effects of nutrition, hygiene, before age 14 adult socioeconomic status attainment, including education, international indexes first job current job, family income per head. The...
