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.

Welfare effects of rural-urban land conversion on different aged land-lost farmers:exemplified in Wuhan city

Rural-urban land conversion is a universal phenomenon in the rapid process of economic development and urban growth.The welfare of farmers who lost their farmland attracted a widespread concern within the society and academia.However,further research about differentiated policies according to the characteristics of different farmer groups is still need to be conducted.This article divides the land-lost farmers into three age groups:younger than 45,45-65,and more than 65.It proposes a welfare index system including eight functional areas based on different age groups of affected farmers,taking four districts of Wuhan City as case study area.Fuzzy mathematics method is used to derive the aggregated welfare effect index.Our analysis show that the overall welfare levels of land-lost farmers of all age groups declined,but with a varying degree,with the level of welfare in those farmers who are 45-65 years old,younger than 45 years old,and older than 65 years old decreased by 18.7%,16.6%,and 12.7%,respectively.The direction and degree of effects on the functional activity index varies among different groups.Economic conditions,living environment,health,and social participation of all age groups decrease while social security and housing conditions increase.On the other hand,development opportunities,social communication,and leisure have different changing directions in different age stages.These results call for differentiated and tailor-made compensation policies for land-lost farmers,towards improving the welfare levels of all farmers and reduce the disparity among them.

Rural-urban Migration, Rural Household Income and Local Geographical Contexts——A Case of Northwestern Guangxi, China

This paper aims to examine New Economics of Labor Migration (NELM) in the northwestern Guangxi, China and investigate the relationships among rural-urban migration, rural household income and local geographical contexts. Stratified sampling and typical case study were adopted and 236 questionnaires were collected from four vil- lages, Daxin, Lixin, Longhe and Yongchang. We analyzed the rural-urban migration rate, household income and local geographical factors, focusing on the ratio of remittance income to total household income. Data descriptions and sta- tistical methods, such as Pearson Chi-square test, Contingency coefficient, Eta, Pearson correlation coefficient, t-test, multiple comparisons (LSD test, Tamhane T2, Dunnett T3 and Dunnet C test) were used. The results are as follows. Rural households’ income is diversified in survey villages so the motivation of rural-urban migration in the study area can be partly explained by NELM. The migration rate of households (the percentage of households with migrants in survey households) in survey villages varies from 50% to 86%, while the proportion of remittance income to house- hold income is in the range of 30% to 80%. In the village of Yongchang, with the least average arable land area per household, the remittance income plays a vital role in household income (80%). And the statistical findings show that the proportion is significantly and negatively correlated with arable land area per household. The conclusion is that di- rect effect of migration, i.e., the contribution of remittance to household income, is negatively correlated with the con- tribution of resources to local income.

Economic Growth, Demographic Change and Rural-Urban Migration in China

Is China able to maintain fast growth after three decades？ This paper tries to answer this question by： 1） arguing that factors contributed to sustained long-run growth at supply side;2） focusing on contributions of demographic dividend especially that of rural-urban migration;and 3） analyzing rural demographic change with information collected through village-wide household survey.Policy alternatives to realize remaining potential demographic dividend are proposed based on the analysis of changing rural demographic structure.

Rural-urban Migration,Rural Household Income and Sustainable Development in Rural Areas of China

The objective of this paper is to investigate the rela- tionships among rural-urban migration,rural household income and sustainable development in rural areas of China.The typical case study is done and 288 questionnaires are collected from five villages in Hebei and Guangxi provinces,China.The migration and remittance status,household income and sustainable devel- opment of rural areas are analyzed on the basis of questionnaires. Rural-urban migration is becoming a part of routine life in rural areas.And remittance is an important component in rural house- hold income.Rural-urban migration increases the arable land area per labor,which releases the tight human-land relationship in villages.In total,the migration increases the rural household in- come and accelerates the sustainable development of rural areas.

NEW RURAL SPACES: THE IMPACT OF RURAL INDUSTRIALIZATION ON RURAL-URBAN TRANSITION IN CHINA

Since the 1980s, rural-urban transition has been becoming one of the most important aspects in China’s fast transformation from traditional to modern modes. From the perspective of change of rural space, this paper examines the impact of rural industrialization on the rural-urban transition. After an introduction to the issue of rural-urban transition in rural-urban continuum, a historical overview of the transformations of China’s rural space in economic, social and geographical structure is presented. This is followed by an analysis of regiotal uneven development among provinces in rural industrialization and rural-urban transition. It is concluded that the fast industrialization of rural area has brought on many radical transformations of rural space in China, especially on the formation of new rural economic, social and geographical spaces and the uneven development of rural-urban trgnsition among the eastern, central and westem areas.

Coordinating rural-urban education and institution innovation

In order to implement the spirit of the Sixteenth National People＇s Congress to accelerate development of rural education, deepen reform of rural education, guarantee a well-off society, and harmonize rural and urban development, coordinating ruralurban education is the key to China＇s development. At present, the rural-urban coordinating education is influenced by many factors, including rural-urban income difference, rural-urban educational resources difference, rural-urban background difference, and rural- urban institutional difference. In order to realize the coordinating development of rural-urban education, we need innovation in ＂Hukou＂ institution, land institution, financial institution and rural education institution. Institution innovation would be the guarantee to the coordinating rural-urban education.

Welfare Balance of Different Interest Groups During Rural-urban Land Conversion

Rural-urban land conversion is currently a common social economic phenomenon during the process of economic development and rural urbanization in China. Rural-urban land conversion is positively effective as far as social and economic benefits are concerned (Yang, 2002), but its negative effect is also evident, resulting in such problems as low efficiency of rural land configuration and loss of social welfare. Consequently, farm-ers should also have an equal chance to enjoy the social welfare enhanced by land conversion. Based on the theories of welfare economy, this paper puts forward policy suggestions by discussing the welfare changes of various interest groups, builds the model of welfare distribution, and analyzes the conditions of maximizing social welfare. The absolute and opposite value of social welfare is closely related with the speed of rural-urban land conversion, and governments should give farmers and collectives fair compensa-tion to make up for the utility loss caused by land expropriation, which are conclusions drawn from this paper. This study aims to provide a theoretical basis for regulating targets and evaluation criteria, realizing the mechanism and implementation of public po-lices during rural-urban land conversion.

Path Choice on Rural Industrial Upgrading in the Process of Rural-urban Integration in Binhai New Area

With methods of reference research and field research, the current situations of rural industrialization in the process of rural-urban integration in Binhai new area are analyzed and some problems in the process of integration in the new area are pointed out, such as difficulties in breaking dual economic structure in urban and rural areas, imbalanced economic development in the area and inadequate development of the third industry. And relevant countermeasures are proposed: optimizing agriculture industrial structure and promoting agricultural industrialization to form urban agricultural model of Binhai new area focusing on facility agriculture, park agriculture and high-end agriculture and to realize the intensive growth of agriculture; rationally distributing rural industrial structure to form regional leading industry and playing the guiding role of industry to achieve industrial adjustment improvement; quickening the construction of the third industry centering on service to form the service system of modern countryside and the leading role of modern service industry so as to achieve rapid development of the third industry.

Effect of Digital Economy Development on Rural-Urban Income Disparity: Evidence from China

Promoting income equality between urban and rural residents is one of the main goals of China’s social progress and economic development.It is also a necessary means to achieve“common prosperity.”Digital economy can effectively promote economic development,the adjustment of industry structure and industry upgrading,as well as increase the disposable income of urban and rural residents,which is theoretically beneficial to rural-urban income disparity.An empirical analysis is conducted based on the data of 30 provinces,municipalities,and autonomous regions in China from 2013 to 2020.The findings demonstrate that the growth of digital economy helps lessen rural-urban income disparity and has a significant effect in East China and North China.

What Influences The Family Migration Decision of China’s New Generation Rural-urban Migrants? A Multilevel Logistic Regression Analysis

The massive scale of new-generation rural-urban migrants in China has attracted extensive scholarly attention in recent years.While previous studies on China’s rural migrant workers focus on migrants’settlement intentions,migrants’family migration decision-making and the intergenerational differences between the old-generation migrants and new-generation migrants are underexplored.Based on the data of the 2017 China Migrants Dynamic Survey,this paper adopts a multilevel logistic regression approach to explore family and destination factors influencing the family migration decisions of China’s new generation of rural migrant workers.The empirical results reveal that both the migrants’family and destination attributes significantly influence their family migration decision.The demographic and socioeconomic characteristics of the family have been pivotal factors underlying the family migration decision of China’s new generation rural-urban migrants,while 16.9%of the chances are explained by between-destination differences.Self-employed migrants with housing properties in host cities,long migration duration and high-income levels are more likely to migrate with their family members.Yet,the possibility of family migration is found to be significantly and negatively correlated with the age,education level,number of children and inter-provincial mobility of the new generation of migrant workers.In addition,new-generation rural-urban migrants’family migration is more likely to be found in cities with service-oriented industry structures,better environmental quality,and higher hukou barriers which is possibly related to more job opportunities.These research findings not only complement the existing literature on China’s new generation of rural urban migrants,but also have important policy implications for reforming the hukou system and enhancing social integration of the rural-to-urban migrant population.

Between plaza and peak: a montological perspective on verticality and urbanization in highland Peru

Under the influence of concentrated and extended urbanization,Andean cities and the different altitudinal zones of their“hinterlands”are experiencing profound changes in land cover—from the central plazas up to the highest peaks.The complex regional-geographic characteristics of these socioecological systems,such as the vertical complementarity of land use,require a montological perspective on verticality and urbanization:it transcends disciplinary approaches and can be crucial to properly interpret the trajectories of land cover change and formulate hypotheses for future practiceoriented research.Which trajectories of land cover change characterized altitudinal zones of Andean cities and their surroundings over the last three decades?Are there similarities that allow for the formulation of more general hypotheses?Using the Peruvian cases of Cusco and Huaraz,and combining a traditional altitudinal zonation model of land use in Peru with direct field observations and GIS-based analyses of remotely sensed data from 1991,2001,2011,and 2021,this study identifies the main trajectories of land cover change in the Quechua(>2300–3500 m),Suni(>3500–4000 m),and Puna(>4000–4800 m)regions—and finds insightful similarities between Cusco and Huaraz:(1)an impressive area of built-up land substitutes grassland in the Quechua,which,following regional altitudinal zonation models,is characterized by irrigated and rain-fed cropland;(2)an unexpected expansion of irrigated cropland takes place in the Suni,which,in theory,often lacks irrigation infrastructure and is mostly used for rain-fed tuber cultivation;and(3)a clear change from“other land”to grassland occurs in the Puna—where grassland is thought to predominate,anyway,since pre-Hispanic times.Hypothesizing that these changes reflect the interplay between speculative fallow,agricultural intensification,and ecological restoration,the results can be read as vertically complementary,local manifestations of concentrated and extended urbanization in a formerly peripheral mountain region of the Global South—and they underscore the need to overcome mental city-mountain dichotomies for a socially inclusive and ecologically balanced Andean development between plaza and peak.

Effects of population aging on the mortality burden of related cancers in urban and rural areas of China, 2004–2017: a population-based study

Objective:China is a developing country with urban–rural disparities and accelerating population aging.Therefore,quantifying the effects of population aging on the cancer mortality burden is urgently needed.Methods:Using data from China’s death surveillance datasets(2004–2017),we decomposed and quantified the effects of population aging and factor variations on cancer mortality rates in urban and rural China during 2004–2017 through a decomposition method.R ratios were used to assess the extent of the mortality decreases attributable to factor variations offsetting the increases attributable to population aging for 4 aging-related cancers(lung,colorectal,esophageal,and stomach cancer).Results:Overall,population aging has led to continued increases in cancer mortality rates in China during 2004–2017(mortality rates attributable to population aging:8.63/100,000 for urban men,4.21/100,000 for urban women,11.95/100,000 for rural men,and 5.66/100,000 for rural women).The 4 cancers displayed 3 patterns.The mortality rates from lung cancer in rural China and from colorectal cancer nationwide increased because of both population aging and factor variations.Population aging was primarily responsible for the growing mortality due to lung cancer in urban areas.However,for esophageal and stomach cancer,the effect of population aging was not dominant,thus resulting in decreases in mortality rates.Conclusions:Health resource allocation should prioritize areas or cancers more adversely affected by population aging.The burden of cancer will continue to increase in the future,because of rapid population aging,but can still be offset or even reversed with enhanced cancer control and prevention.

Fiscal Expenditure and Income Gap between Urban and Rural Residents: An Empirical Study Based on Malmquist Index and Spatial Econometrics

Based on the analysis methods of non-parametric Malmquist index and spatial econometrics as well as the provincial panel data in 2007-2010, this paper estimates the efficiency of fiscal expenditure from local governments in china in terms of reducing the income gap between urban and rural residents for the first time and evaluates the spatial correlation and heterogeneity of this efficiency. The results have shown that the fiscal expenditure of most provinces is of low efficiency in reducing the income gap between urban and rural residents, and the expenditure efficiency of local governments is not relevant to their levels of economic development. Besides, the efficiency on reducing the urban-rural income gap between different regions of China has a tendency of convergence. But this is mainly reflected inside the regional economic belt. There is significant difference between the efficiency of each economic belt. The central region has the highest efficiency in a rising trend, the western region has the lowest efficiency in a downward trend, while the eastern region is relatively stable.

Disparities in colonoscopy utilization for lower gastrointestinal bleeding in rural vs urban settings in the United States

BACKGROUND Lower gastrointestinal bleeds(LGIB)is a very common inpatient condition in the United States.Gastrointestinal bleeds have a variety of presentations,from minor bleeding to severe hemorrhage and shock.Although previous studies investigated the efficacy of colonoscopy in hospitalized patients with LGIB,there is limited research that discusses disparities in colonoscopy utilization in patients with LGIB in urban and rural settings.AIM To investigate the difference in utilization of colonoscopy in lower gastrointestinal bleeding between patients hospitalized in urban and rural hospitals.METHODS This is a retrospective cohort study of 157748 patients using National Inpatient Sample data and the Healthcare Cost and Utilization Project provided by the Agency for Healthcare Research and Quality.It includes patients 18 years and older hospitalized with LGIB admitted between 2010 and 2016.This study does not differentiate between acute and chronic LGIB and both are included in this study.The primary outcome measure of this study was the utilization of colonoscopy among patients in rural and urban hospitals admitted for lower gastrointestinal bleeds;the secondary outcome measures were in-hospital mortality,length of stay,and costs involved in those receiving colonoscopy for LGIB.Statistical analyses were all performed using STATA software.Logistic regression was used to analyze the utilization of colonoscopy and mortality,and a generalized linear model was used to analyze the length of stay and cost.RESULTS Our study found that 37.9%of LGIB patients at rural hospitals compared to approximately 45.1%at urban hospitals received colonoscopy,(OR=0.730,95%CI:0.705-0.7,P>0.0001).After controlling for covariates,colonoscopies were found to have a protective association with lower inhospital mortality[OR=0.498,95%CI:0.446-0.557,P<0.0001],but a longer length of stay by 0.72 d(95%CI:0.677-0.759 d,P<0.0001)and approximately$2199 in increased costs.CONCLUSION Although there was a lower percentage of LGIB patients that received colonoscopies in rural hospitals compared to urban hospitals,patients in both urban and rural hospitals with LGIB undergoing colonoscopy had decreased in-hospital mortality.In both settings,benefit came at a cost of extended stay,and higher total costs.

On the Process of Peasant Workers' Transformation to Urban Residents

The unique two-stage "Chinese path" of China’s ru-ral-urban migration, which cannot be fully explained by classical theories of economic development, makes us to give peasant workers’ transformation to urban residents a top priority. On the basis of fully explaining peasant workers’ transformation to urban residents, a method for measuring its process has been advanced and then confirmed with the data of March in 2005 from surveys to peasant workers in Wuhan. Finally, the suggestions of acceler-ating peasant workers’ transformation to urban residents to pro-mote the construction of a harmonious society have been drawn from the analysis.

Correlates of first dose of measles vaccination delivery and uptake in Indonesia

Objective:To determine health systems-related,familial,and cultural factors which influence the delivery and uptake of measles vaccination in Indonesia.Methods:Logistic regression analysis of data collected during the 2007 Indonesian Demographic and Health Survey was undertaken by the authors to investigate these factors.The 2007 Indonesian Demographic and Health Survey dataset is a nationally representative,randomly sampled survey containing 15 065 children aged between 9 and 59 months.Results:72.8%of children had received the measles vaccine.Vaccination coverage was similar for males and females;however,coverage was higher amongst urban children,80.1%,compared to 68.5%in rural areas.The key findings of the regression analysis were congruent with the results of previous research targeting vaccination coverage.After controlling for all other factors,maternal age,maternal education,wealth, the use of a skilled birth attendant,and postnatal check-ups were positively and significantly (P【 0.01) correlated with measles vaccination.The number of children per household was negatively correlated(P【0.01).Conclusions:In order to enhance measles vaccination coverage in Indonesia,delivery to,and uptake by,rural and low socio-economic populations require substantial improvements.Mass health education and health systems improvements are also required.
