Optimal Mode of Agricultural Moderate Scale Management Based on Measurement of Moderate Scale of Wugang City in Henan Province

The issue of agricultural moderate scale management is always a hot spot. In 2016,the No. 1 document of the central government once again set forth the requirement of bringing into play leading role of moderate scale management in various forms of agriculture. In the economic new normal,the solution to this issue is of great significance to promoting agricultural modernization. However,there are still problems such as unsmooth transfer of rural labor force,fragmentation of rural land management and low benefit of land scale management. Taking Wugang City in Henan Province as an example,this paper attempts to find out the optimal land management scale in accordance with the actual situation in Henan Province. It is concluded that small family farm is the optimal mode for agricultural moderate scale management.

Literature Review of Agricultural Scale Management and Efficiency

Scale management remains the core position in entire development process of the economics and is a major issue of academic research and government concern. Focusing on related problems of agricultural scale management,this paper explored 4 aspects of past literature.( i) It defined the agricultural scale management based on economies of scale theory and changes in returns to scale.( ii) From the perspective of the returns to scale of grain production,there are changes in returns to scale of China's grain production,but the measured changes are not significant.( iii) Existing analysis on factors influencing agricultural scale management mainly includes factors influencing farmers' willingness of scale management and restrictive factors of implementation of scale management.( iv) In studies of the relationship between land management scale and production efficiency,many scholars made qualitative and quantitative analysis on land scale efficiency on the basis of economic indicators they defined,but they reached different conclusions. Finally,it summarized literature and pointed out several issues needing special attention in this field.

Coupling Relationship between Integrated Land Consolidation and Farmland Scale Management in Villages over Coal Resources:A Case Study of Zezhou County in Shanxi Province

Through field sampling survey of 18 villages over coal resources in 3 townships and towns in Zezhou County,Jincheng City,Shanxi Province,this paper analyzed the favorable conditions and obstacles for villages over coal resources to carry out farmland scale management.On this basis,combined with the integrated land consolidation measures in villages over coal resources and their effectiveness,and using the principles of system dynamics,it studied the coupling relationship between integrated land consolidation in villages over coal resources and farmland scale management and built a coupling model.It found that the integrated land consolidation system of villages over coal resources has a coupling relationship with the external and internal conditions of the farmland scale management system at the regional and project scales.The two systems interact with and influence each other through the"bridge"of"agricultural modernization condition".The study indicates that at the same time of integrated land consolidation of villages over coal resources caring about the improvement of internal conditions,it is also necessary to improve the external conditions of farmland scale management through regional scale measures such as laws and policies,to support the implementation of land consolidation projects,and realize farmland scale management.

Do large-scale farmers use more pesticides? Empirical evidence from rice farmers in five Chinese provinces

It is of great theoretical and practical significance to understand the rules of the differences in pesticide use behaviors between large-scale and small-scale farmers,so as to regulate the behavior of farmers differently and improve the quality and safety of rice.The overall pesticide use behavior of large-scale farmers was characterized by large doses and high application frequency,while that of small-scale farmers was characterized by small doses and low application frequency.The econometric test showed that(i)the proportion of staple food ration has a significant negative impact on the single dose exceeding the standard and pesticide application frequency of small-scale farmers,and the increase of the proportion of staple food ration will reduce the demand among small-scale farmers for pesticides;(ii)yield effect has a greater impact on the frequency of pesticide application by large-scale farmers,and the large yield effect will increase the frequency of pesticide application among large-scale farmers.Therefore,in pesticide use behaviors,large-scale farmers should reduce pesticide quantity and increase efficiency,while small-scale farmers improve the level of plant protection.

论高等学校大型仪器设备的开放与共享

大型精密仪器设备是高等学校优质的教学资源,是进行高水平实验教学和科学研究的重要工具,也是高等学校办学实力和科研水平的重要标志。但由于高等学校大型仪器设备封闭式管理,导致重复购置;购置可行性论证不足,造成严重的资源浪费;购入后维护经费不足,造成大量仪器设备闲置等原因,是高等学校大型仪器设备利用率不高的主要原因。这些因素制约了高等学校大型仪器设备的开放与共享,因此,高等学校建立开放共享的管理机制,形成组织保障、经济保障和设备效益评估机制,建立大型仪器共享平台,设立大型仪器设备使用基金,鼓励大型仪器设备对外开放,服务社会。提高高等学校仪器设备利用率,保障教学科研工作正常进行,促进高等学校的可持续发展。

Large Scale Infrastructure Projects: The Art of Project or Change Management?

Although it is generally understood that change is a fundamental component of managing projects in the construction industry in general and an inevitable challenge for large scale infrastructure project in particular, there has been little to no attention in the literature to understand change in this context from a more holistic perspective. For this purpose, this work looks at change through the eyes of a framework of six batteries of change that seem essential to charge an organization's capabilities for change. The framework brings together the expertise of four specialists that all have developed their insights over many years of study and practice, and has been validated through an extensive review of the management literature on organization development and change. Reflections on the application of this model in the construction industry and in large scale infrastructure projects demonstrate that energizing organizations to successfully deal with change goes beyond the traditional techniques of managing change from a program or project management perspective. Assessing the six batteries of change in this context can help organizations to develop capabilities for change that build change energy by balancing formal/rational methods with informal/emotional interventions at both a local(department/subproject) and global(business) level.

农户的非农就业如何影响中国的土地流转?

To clarify the impact of non-agricultural employment on rural land circulation in China,we built logit models using the Chinese Household Income Project 2013 dataset,which includes 18,948 household samples over 15 provinces,126 cities and 234 counties of China in 2013.We use the proportion of non-agricultural income,the proportion of non-agricultural laborers and non-agricultural fixed operating assets to reflect the degree of the households’dependence on agriculture,the degree of the households’laborers committed to non-agricultural employment and the stability of non-agricultural employment,respectively.The results show that the stability of non-agricultural employment is an important reason for farmers to transfer out their land,and an increase in non-agricultural income is the fundamental reason.The proportion of non-agricultural assets has the greatest impact on the decision to transfer land,followed by the proportion of non-agricultural income.Per unit increase in the non-agricultural income ratio has a stronger effect on the transfer-out decision than it does on the transfer-in decision,which is a 0.09 increase of the probability of transfer-out the land and a 0.07 decrease of the probability of transfer-in the land.In terms of regional differences,when considering the impact of non-agricultural employment on the land transfer-out decision,the impacts of non-agricultural income and labor force are the greatest in the Central region.The impact of non-agricultural assets is the greatest in the Eastern region.For the Eastern region,the decision to transfer out land is mainly affected by non-agricultural assets and the non-agricultural labor force,and the decision to transfer in land is mainly affected by non-agricultural assets.In the Central and Western regions,the decision to transfer out land is mainly affected by non-agricultural assets,non-agricultural income and the non-agricultural labor force,in that order.The decision to transfer in land in the Central region is not significantly affected by non-agricultural employment.The decision to transfer in land in the Western region is mainly affected by non-agricultural assets,non-agricultural labor force and non-agricultural income,in that order.We note that non-agricultural assets have a prominent impact on land transfer,which shows that the stability of non-agricultural employment has an important impact on land transfer decision-making.Vocational training for rural labor forces may be an effective means to promote stable non-agricultural employment and simultaneously facilitate rural land circulation,especially in Central and Western China.
