摘要:
With the rapid development of China's economy, the agricultural industry chain has a new mode of operation. The rise of big data technology can collect the relevant information of the agricultural industry chain in all aspects more rapidly, accurately and comprehensively, so that the agricultural production, logistics and information flow can be unified, so as to realize the optimization of the resource structure of the industrial chain, and the operation efficiency is higher. In this paper, the analysis method combined with big data was used to construct the industrial chain of ecological agriculture. The ecological agriculture industry in Wuwei was regarded as the specific research object, and a large amount of empirical data was collected by means of consulting literatures and field surveys. The input analysis and output analysis of the agricultural production in Wuwei were carried out and the original industrial chain model was evaluated, and the deficiency of the influence factors was improved. The agricultural industry chain was the developmental situation of a dynamic organization, which had important methodological significances. This paper attempted to put forward some suggestions for the rational development of the agricultural industry chain.

摘要:
With the continuous development of economy and the integration of the Internet information network, the network language is playing an increasingly important role in people's lives. Since the economists put forward the linguistic economics in 1965, the economic value of language has become the consensus of the people of all countries, and now it is a new and hot topic to study and analyze the English network language. In this paper, a system for evaluating the economic value of English network language was designed. Analytic hierarchy process (AHP) and qualitative methods were used, and the economic value of network language was quantified.

摘要:
This paper develops an incomplete-markets model of investment timing by a firm's controlling shareholder, who is exposed to idiosyncratic risk and pursues private benefits at the expense of outside shareholders. We show that the timing of investment selected by the controlling shareholder reflects a tradeoff between his incentives to pursue private benefits and the costs of nondiversification. The firm may overinvest or underinvest depending on the magnitude of the agency conflicts. Moreover, our theoretical model predicts that increasing the cash flow ownership of the controlling shareholder will decease the total social welfare, which provides novel testable empirical implications for investment.

Social capital;Water user group (WUG);Water use efficiency
摘要:
Using group-level and household-level data collected in 2006-2007 in two districts in Hubei Province of China, we investigate social capital and water source variables and assess the factors influencing the formation of a sub-group, which is a sub-set of the original water user group (WUG). We use a probit model and regression analysis to examine the impact of sub-group formation on the adoption of alternate wetting and drying (AWD). Results show that when social capital is strong, farmers tend not to form sub-groups because strong social capital can prevent overuse of water. However, when social capital in a group is weak, farmers need to avoid overuse of water by forming a sub-group. Therefore, if farmers in the group of weak social capital are physically constrained and thus fail to form a sub-group, overuse of water is more likely. Such failure occurs when the existence of many water sources physically prevents farmers from forming a sub-group. We also found that when social capital is strong, farmers adopt the AWD practice even without forming a sub-group. ©2010 Elsevier B.V. All rights reserved.

摘要:
Few studies of the pig production efficiency are from the perspective of animal welfare. Therefore, this study conducted a comprehensive evaluation of pig welfare levels based on survey data from 773 pig farmers from 23 counties in the Chinese provinces of Hunan, Zhejiang, Guangdong, Guizhou, and Shanxi. This study used the Delphi method, Analytic Hierarchy Process (AHP), and Data Envelopment Analysis (DEA)-Tobit regression model to analyze farmers’ pig production efficiency and its influencing factors. This paper found that most farmers’ pig production efficiency is low, and the DEA is invalid. Only 2.9% of pig farmers’ who breed pigs are at the optimal level in terms of welfare, and their production efficiency is relatively high. In contrast, 49.34% of the farmers are at the medium welfare level, and compared with the farmers at the optimal welfare level, these farmers’ pig production efficiency is low. Additionally, the farmers’ age, gender, and number of years of experience with pig breeding have a significant effect. Furthermore, the scale of pig breeding and feeding type, the agriculture facilities for the central treatment of waste in local areas, and the availability of local agricultural science and technology personnel have a considerable influence on pig production efficiency. © 2017 Li et al.

摘要:
While numerous studies have investigated the relationship between oil volatility and stock returns, it is surprising that little research has examined the quantile dependence and directional predictability from oil volatility to stock returns in BRICS (Brazil, Russia, India, China, and South Africa) countries. We address this issue by using the cross-quantilogram model proposed by Han et al. (2016). The empirical results show that, overall, oil volatility has a directional predictability for the stock returns in BRICS countries. When the oil volatility is in a low quantile (lower than its 0.1 quantiles), it is less likely to show either a large loss or a large gain in the stock market. In contrast, there is an increased likelihood of either large loss or a large gain in the stock market when the oil volatility is in a high quantile (higher than its 0.9 quantiles). The directional predictability from the oil volatility to stock returns depends on the net position of oil imports and exports of these BRICS countries in the oil market. The net oil exporters (Russia and Brazil) are less likely to have large gains and large losses in the stock market than are the net oil importers (India, China, and South Africa) when the oil volatility is in a low quantile. The net oil exporters are more likely to have large gains and large losses than are the net oil importers when the oil volatility is in a high quantile. The results are robust to change in the variable of oil volatility and the sample interval. © 2018 Elsevier B.V.

摘要:
This paper investigates the risk transmission and hedging strategies between natural gas market and stock markets. We propose a multivariate GARCH framework which combines regime switching with multivariate long memory and asymmetry GARCH. Results show that there exists granger causality from natural gas market to the Chinese stock markets in crisis regime. Dynamic correlations between these markets are vulnerable to extreme weather, government policies and financial crisis. When looking at the optimal design of a natural gas-stock portfolio, we find that investors in stock markets should have more stocks than natural gas asset in order to reduce their portfolio risk. © 2018 Elsevier Inc.

摘要:
农户种植行为的研究对农业政策的制定有重要启示作用,有利于政府采取有效措施引导农户种植行为变化符合现代农业发展要求,对促进农业现代化发展有重要意义。基于农户作为农业生产决策者的视角,采用湖南省典型灌区农户调查数据,运用普通二分类Logistic回归模型,探讨影响农户种植行为变化的因素。结果表明,灌区种植户文化素质不高,务农劳动力以中老年人为主,作物种植规模小,土地流转现象较少,田地细碎化程度较高;户主年龄、地区差异、农户家离集贸镇最近的距离、水资源是否匮乏以及土壤类型对种植行为变化有显著正向影响。基于实证研究结果,政府要因地制宜的做好种植结构调整规划,向农户推广适宜的农业栽培技术和作物品种,完善农田水利基础设施,加大农村交通基础设施建设,建立农产品交易场所,引导和规范土地流转,创新农业经营组织形式和发展适度规模经营,此外农户自身需改变传统小农生产方式,积极学习掌握现代农业知识。

摘要:
本文以湖南省家庭农场调查数据为样本,构建以企业家才能和经营环境为中介变量的结构方程模型,实证检验农业扶持政策与家庭农场经营绩效的关系。研究发现,农业扶持政策对家庭农场经营绩效的直接效果不显著,但通过两条中介路径的间接效果显著。从两条中介变量的路径系数来看,以经营环境为中介的路径能够更高效地提升家庭农场的经营绩效。据此,应完善土地流转、农业社会化服务、家庭农场经营管理培训等方面的扶持政策。

摘要:
我国从2004年开始进入增量式农村金融改革时期。文章基于历史和逻辑的分析,首先研究了我国农村金融"双线"改革思路的形成过程和基本内容,即中央银行的改革思路是通过整合民间资本发展小额信贷来实现普惠金融,而银监会的改革思路是在严格控制风险的前提下,通过增设新型农村金融机构来填补金融服务空白。在此基础上,文章分析了这种"双线"改革对农村金融改革进程和效果产生的影响,并提出了"双线"改革思路协调的基本框架和对策建议。
