Study on the Impact of Collective Commercial Construction Land Entering the Market on Rural Residents’Income:Taking Deqing County,Zhejiang Province as an Example

The entry of collective construction land for business purposes is an important measure for deepening the reform of the rural land system,promoting the flow of urban and rural factors,and realizing rural revitalization.Since the production of the first batch of pilot projects in 2015,33 county-level cities have participated in the pilot policy by 2023.Deqing County,Zhejiang Province,as the first area to participate in the pilot project,aims to achieve more fruitful results.This paper first examines how promoting farmers’income through the market entry of agricultural land can be achieved,then uses the synthetic control method to quantitatively study the impact of collective operational construction land on farmers’income using panel data from 2011 to 2019,and finally proposes relevant suggestions from the perspective of system reform.

Modelling of Wage and Income Distributions Using the Method of L-Moments

Commonly used statistical procedure to describe the observed statistical sets is to use their conventional moments or cumulants. When choosing an appropriate parametric distribution for the data set is typically that parameters of a parametric distribution are estimated using the moment method of creating a system of equations in which the sample conventional moments lay in the equality of the corresponding moments of the theoretical distribution. However, the moment method of parameter estimation is not always convenient, especially for small samples. An alternative approach is based on the use of other characteristics, which the author calls L-moments. L-moments are analogous to conventional moments, but they are based on linear combinations of order statistics, i.e., L-statistics. Using L-moments is theoretically preferable to the conventional moments and consists in the fact that L-moments characterize a wider range of distribution. When estimating from sample L-moments, L-moments are more robust to the presence of outliers in the data. Experience also shows that, compared to conventional moments, L-moments are less prone to bias of estimation. Parameter estimates obtained using L-moments are mainly in the case of small samples often even more accurate than estimates of parameters made by maximum likelihood method. Using the method of L-moments in the case of small data sets from the meteorology is primarily known in statistical literature. This paper deals with the use of L-moments in the case for large data sets of income distribution （individual data） and wage distribution （data are ordered to form of interval frequency distribution of extreme open intervals）. This paper also presents a comparison of the accuracy of the method of L-moments with an accuracy of other methods of point estimation of parameters of parametric probability distribution in the case of large data sets of individual data and data ordered to form of interval frequency distribution.

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.

Household Income and Expenditure Relationships： A Simultaneous Equation Approach

Income and expenditure are highlighted in this study as they currently affect the quality of life of the Malaysian society. In the Ninth Malaysia Plan （2006-2010） poverty eradication was emphasized as one of the socio-economic targets to uplift those poor households from the fast moving modern sectors of the economy. The primary objective of this paper is therefore to identify income and expenditure relationships among the households of the east coast of Peninsular Malaysia during the current economic downturn. Attempts to analyze household consumption as a share of total income and to identify factors contributing to household income and expenditure have become a topic of interest in literature. A substantial portion of household income devoted to productive loans characterizes the majority of Malaysians as the economy progresses to a more advance stage. A significant and strong relationship between income and types of household expenditure is explored from the socio-economic perspectives. Using primary data a system of simultaneous equations, namely the two stage least squares （2SLS） was applied. This paper identifies crucial variables associated with the income and expenditure. Some of these variables showing high correlation with the total expenditure are the housing loan, automobile loan and educational expenditure.

Intergenerational Transmission of Income Gap for Chinese Urban and Rural Households

An accurate understanding of the intergenerational transmission of income gap is the foundation for theoretical research and policy formulation to address this issue. This paper has employed the method of two sample instrumental variables to effectively integrate CHIP data and CFPS data and correct the temporal income bias, life-cycle bias and coresidence bias, which are common problems in existing studies, and investigated the tendencies of intergenerational transmission of income gap for China's urban and rural households between 2002 and 2012. Results of empirical study indicate that the intergenerational transmission of income gap for China's urban and rural households has been on the decline yet the level of intergenerational transmission is greater for urban residents than for rural residents. This level of intergenerational transmission of income gap in China is at a medium international level lower than that of countries like the United States, Brazil and Japan and higher than that of Sweden and Chinese Taiwan. Further analysis of the intergenerational mobility of various income groups suggests the following: the intergenerational solidification of the bottom and top income groups of urban residents has significantly improved, which is the source for the reduction of intergenerational transmission of income gap. Rural residents of bottom income group are vulnerable to falling into the trap of intergenerational transmission of low income. In order to mitigate the intergenerational transmission of income gap, efforts must be made to improve educational allowance policy and increase the opportunities for children from poor and underprivileged families to receive education and to eliminate the divide of labor markets to create equal job opportunities for each and every worker.

Factors Affecting the Income of Farmers

Based on the introduction of factors affecting the income level of farmers in China,a total of 31 provinces,autonomous regions and municipality cities are taken as samples to select 13 factors affecting the income level of farmers,which are arable land area(X1),disaster area(X2),effective irrigation area(X3),fertilizer application(X4),mobile phone(X5),personal computer(X6),people joining in the new rural cooperative medical care(X7),rural investment(X8),household-use machine(X9),agricultural product price(X10),proportion of labor force with above junior high school education(X11),rural delivery route(X12),and rural electricity consumption(X13).At the same time,factor analysis method is used to analyze the factors affecting the income level of farmers.Result shows that common factors affecting the income of farmers are the agricultural production factor F1,the expanded reproduction factor F2,the information use factor F3,and the output reduction factor F4.At present,education degree of farmers and ability of farmers in grasping information have relatively great impact on the income of farmers,and can effectively promote the income growth of farmers.Scores of F1 in Henan,Shandong and Hebei are generally higher;Jiangsu,Guangdong,Zhejiang and Shandong Provinces have relatively high scores of F2;Shanghai,Beijing and Guangdong have relatively high scores of F3;and Hunan,Hubei and Xinjiang have relatively high scores of F4.Finally,countermeasures are put forward to improve the income of farmers based on empirical study.

财政资金支持与低收入群体持续增收

促进欠发达地区农民持续增收是实现乡村全面振兴的经济基础。本文基于2006—2019年县级面板数据,以脱贫县农民为研究对象,使用合成控制法评估财政资金支持力度下降后欠发达地区低收入群体的收入增长情况及地区异质性。研究发现:与合成县相比,约35.48%的县的农民收入增长幅度上升,约45.16%的县下降,约19.36%的县基本无差异。财政收入端和支出端的共同挤压使得地方政府财政支出压力增大,进一步对地方政府整体财政支出产生约束,进而对不同自我发展能力的地区产生异质性影响。进一步分析表明,产业结构优化与基础设施建设提升了欠发达地区的自我发展能力,为低收入群体持续增收提供了原动力。
