    农业是国民经济的基础,我国农业发展长期严重滞后,造成今天城乡经济、收入差距日益拉大;农村市场狭小,难以适应工业进一步发展的要求;在我国工业已进入新型工业化中期后,增大农业投入成为解决“三农”问题及许多社会问题的关键。我国农业投入制度形成于二元经济结构时期,国家实行工业优先发展策略的大背景下,农业长期难以形成自身资金良性循环。现行农业投入制度存在着许多的弊端和问题,越来越难适应工农业协调发展、城乡协调发展,社会稳定的要求。本文针对我国农业投入制度存在的主要缺陷,运用制度变迁理论、产权理论、公共产品理论、成本——收益分析理论说明了制度、农业投入制度的本质内涵、我国农业投入制度的历史演变以及制度方面...Agriculture is the foundation of the national economy. As a result of backwards of our agricultural development, there has been an increasing gap between urban and rural economy including income. The small rural market is hard to meet the further need of industrial development. In our country, industry has entered into the new type of later middle industrialization. Increasing agricultural input h...学位:经济学硕士院系专业:经济学院经济系_政治经济学学号:X20044103

    The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in pνˉK+p\to \bar\nu K^+ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via pνˉK+p\to \bar\nu K^+ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is 9.6×10339.6 \times 10^{33} years, competitive with the current best limits on the proton lifetime in this channel

    The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the pνˉK+ p\to \bar{\nu} K^+ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via pνˉK+ p\to \bar{\nu} K^+ is 36.9% ± 4.9% with a background level of 0.2±0.05(syst)±0.2\pm 0.05({\rm syst})\pm 0.2(stat) 0.2({\rm stat}) events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is 9.6×1033 9.6 \times 10^{33} years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
