The research concluded peasants' willingness on homestead exiting and influential factors by questionnaire survey and interviewing in two villages with varied levels of economic development in Anhui Province.Comparisons were performed on subjective factors and objective factors were explored by Logistic regression.The results showed that both of education background and homestead use have positive correlation with peasants' willingness on homestead exit;the number of family members has negative effects on peasants in advanced village but the number of migrant workers or members living in cities has positive effects;the area of homestead has positive effects on peasants in underdeveloped village.Therefore,the emphasis should be varied on homestead exit upon village economy and it is necessary to reinforce homestead exit promotion at improving immigrants' reception work,social security,employment,and education. 展开更多

The research reviewed the development trend of vertical greening industry and divided it into four stages as follows: demand exploring phase, theory and technology development and application phases, and ripening phase of vertical greening system. The characteristics in different phases were detailed, providing ref- erences for development of vertical greening industry in future. 展开更多

This paper reveals that agricultural growth trend in China is strongly correlated with the growth of off-farm industries-the curve of net income from off-farm industries reflects the general characteristics of net income of households. That means the increase of net income of farm households is chiefly from off-farm industries,more than from agriculture. The authors therefore conclude that the "poverty" in mountain areas or the gap between mountain areas and plain areas lies in the underdevelopment of off-farm industries in mountain areas. Finally,the authors make suggestions of strategic adjustment of economic structure: 1) present situation of mountain areas in China should be fully considered; 2) a full industrial system is not our desire; 3) advantageous industries should be promoted to create famous products; 4) industrialization and urbanization in mountain areas should be promoted and so on. 展开更多

This study constructs a theoretical framework to analyze the impact of local governmentled construction land supply(LGCLS)strategies on urban innovation.It uses data related to 265 cities in China from 2005 to 2019 for empirical analysis.Its conclusions are as follows.For development stage differences,the impact of LGCLS strategies on urban innovation exhibited an inverted U shape with economic growth.The inflection point occurred when the per capita GDP equaled approximately RMB23,101 in 2008.For regional diferences,the inflection point in eastern China is higher and earlier than that in central and western China;before the inflection point,the positive infuence was more obvious in the central and western regions,whereas after the inflection point,the negative influence was more obvious in the eastern region.For the eastern Yangtze River Delta urban agglomerations and the northwestern resource-based urban agglomerations with relatively high per capita GDP,the negative impact of LGCLS strategies on urban innovation occurred earlier and showed spatial agglomeration characteristics. 展开更多

Unbalanced economic growth is a ubiquitous phenomenon while investigating the regional development at a large spatial scale.Therefore,it is of great significance to analyze the spatio-temporal pattern of regional economic growth and the drivers to understand and facilitate the economic development of low development areas.Taking a county as a fundamental study unit,we used the county-level per capita GDP data on the Loess Plateau from 2005 to 2017,and geographic variables such as slope,elevation,and population density to analyze the spatio-temporal differences and the driving factors of the county-level economic development in the Loess Plateau by employing both conventional and advanced quantitative methods including Exploratory Spatial Data Analysis(ESDA)and the geographic detector model.Our results suggested that:(1)The selected indicators,including absolute difference,the fluctuation of relative difference and total difference of economic development on the Loess Plateau,all show steady increasing trends,respectively.(2)There are 64.5%of the counties with economic development being below the average level of the whole Loss Plateau region.The relatively high developed counties are distributed in the"A"-shaped regions in Inner Mongolia Autonomous Region,Shaanxi,and Henan provinces,however,the low development counties are mainly located in the"V"-shaped regions in Gansu and Shanxi provinces.(3)GDP,investment in fixed assets and urbanization rate are the major driving factors influencing the regional economic development,and the combined effects are far greater than that of any individual factor. 展开更多
