盡管國內外經濟和人口學方面的專家與學者很早就開始了對農村勞動力問題的研究並取得了極大的進展，但是，我國在研究農村勞動力問題時，基於三點：其一，我國國情決定了國外的理論例如劉易斯理論，雖然對研究我國的農村勞動力問題具有指導意義，但卻不能照搬這些理論；其二，從國內看，我國對該問題的研究重視定性分析而定量分析明顯不足；其三，缺乏對我國占國土面積69 、人口56的山區農村這一特殊區域內的勞動力開發利用及轉移的專門性研究。為了彌補這三個缺憾，論文採用經濟計量學的數量分析方法，利用實際調查資料，藉助tsp軟體，建立了以外出勞動力數量為被解釋變量，城市化率、農村產業結構、城鄉收入差距、農村社會基礎設施建設、農村勞動力素質以及人口自然增長率六個變量為解釋變量的模型，通過對該模型進行經濟學、統計學、經濟計量學三個方面的檢驗，得出如下結果：城鄉收入差距和城市化率是影響山區農村勞動力開發利用及轉移的最重要的兩個因素；農村社會基礎設施建設和農村勞動力素質是較為重要的兩個影響因素；而農村產業結構和人口自然增長率相對來說是較不顯著的影響因素。據此，本文提出了在研究山區農村勞動力開發利用及轉移問題時，應慎重對待城鄉收入差距、城市化水平、農村勞動力素質、農村產業結構、農業機械化五個問題。A lot of areas have already become the fragile district of the ecology. the mesoscale ( mm5v3 - 5 ) model was used to simulate the change of temperature, heat flux by means of changing landuse according to the survey data about the land degradation and renewing in the west of liaoning, which used data in june, july and august, 2001

向農村發放政策性貼息小額支農貸款一直是學術界和各級政府比較公認的解決農村貧困人口，促進農村發展的有效途徑，從現有的理論上看，一定范圍內的小額貼息貸款的發放，會促進農業和農村的發展，提高農村貧困家庭的收入水平，而小額貼息貸款是不是能夠提高農戶的收入水平，貸款戶的增收情況同當地的平均增收額比較，效果怎樣，這是本文所要解決的問題，本文通過對貸款農戶的調查，在收集大量第一手材料的基礎上，將各縣市區所有被調查數據進行了匯總，統計出貸款戶收入變化情況以及與當地的平均增長額的對比情況，將被調查農戶的貸款額，投資領域進行了對比，並與當地非借款戶的當年收入增加額進行了比較。用定量比較和縱向比較的方法研究不同投資領域、不同貸款額、不縣域環境的貸款戶增收額及其相互關系。來說明財政貼息小額支農貸款對農戶收入的影響，分析政策性小額支農貸款對增收的影響因素，論述政策性貼息小額支農貸款的政策性缺陷及管理上的不足，並結合當今國內外政策性支農貸款的政策和管理方式，對我國政策性小額支農貸款的政策制定及管理模式提出了個人的一些見解，筆者認為發揮政策支農貸款的支農作用的根本是推進農村金融體制改革和政治體制改革，改善農村金融服務，創造一個競爭、規范的農村金融環境，有限的貼息貸款解決不了農民的信貸資金需求問題。Theoretical model of self - mixing interference in a linear frequency modulated laserdiode is presented by using the dynamic theory of semiconductor laser with weak external optical feedback. the characteristics of oscillation frequency shift and output power changes of the laser diode are analyzed by using the theoretical model. the absolute distance from front facet of laser diode to target can be found by measuring spectrum of output power of the laser diode
