This paper is mainly the dynamic input-output model that the time lag is one, which is base on the above models. After studying, we consider stochastic factor step by step in it, namely when consumption coefficient matrix is stochastic (when investment matrix is stochastic, it is almost same. So we dont research it), and they are both stochastic, then we research the stable increase solution. We utilize the means of the modern stochastic analysis and Markov process, that the stochastic dynamic input-output model don not exist the stable solution is proved. Namely, economic system must is adjusted constantly. The probability that the collapse time of the economic system is o is one.

本文对在上述基础上构造的一类时滞为1的动态投入产出模型，进行了深入研究，将随机因素逐步考虑进去，即对投入产出消耗系数矩阵为随机的情况(投资系数矩阵为随机的情况与投入产出消耗系数矩阵为随机的情况大致相同，这里就不再证明)，以及二者同时为随机矩阵时所得到的动态投入产出模型的稳定增长解问题，利用现代概率分析及马氏过程的工具，证明了不存在随机动态投入产出模型的稳定增长解；即投入产出模型反映的经济系统必须经常进行调整，其崩溃时间为无穷大的概率为零。

By employing the local Lipschitz condition and Picard sequence, the local existence-uniqueness of solutions of stochastic functional differential equations of Ito-type is firstly obtained. Furthermore, a continuation theorem for stochastic functional differential equations of Ito-type is given by using stochastic analysis technique and the quasi-boundedness condition. Finally, by establishing some delay differential inequalities and using properties of H_m-functions, a stochastic version of Wintner theorem and the global existence-uniqueness of solutions of stochastic functional differential equations of Ito-type are given. The results generalize the earlier publications.

The thesis selects the American constitutional protection on private property law history from the establishment of the United States to the New Deal as study theme, and applies the theory of increasing returns path dependence and evolutionary path dependence from Oona A. Hathaway to normatively analyze this law history. Furthermore, it draws some useful conclusions on characteristics of increasing returns path dependence and evolutionary path dependence on the changing history of American constitutional protection on private property law in a Common Law System, and it also takes a few steps on applying path dependence theory on studying law history in a continental law system in our country.

In the background dependence of political civilization,from the mercy and bounty of governor to the enjoyment and request of own rights embodies the efforts and struggles of the proletariat in order to constitute the socail assistance legal institutions,which offers the room of political system where the social assistance legal institutions are able to exist and develop and strengthen;In the background dependence of economic system,the simple truth which the economic foundation determines the superstructure exerts its advancing logic concretely and really,where the gap between the poor and the rich will be widened continuely in the condition of market economy,and the dependence on the social assistance legal institutions for the poor will be more rainforced,and the request of rights for social assistance will become intense increasingly;In the background dependence of cultural tradition,the relief ideology such as Great Harmony Society,the ideality of equal wealth and the pursuit of the idea that those who have no kin and cann't support themselves can all be cultivated and so on which goes back to ancient times has been depositted into a luscious cultural tradition and Confucianism allegates implementing the humanity politics and sparkplugs cultivating and compensating people,which results in the thoughts of taking civilian as the foundation that occupy the inrooted station in Chinese culture,and the arrangements of social assistance legal institutions response the continue of renation in Chinese traditional culture;In the background dependence of internationalization,the ideaistic assimilation and the spread of arterial values quicken the speed of civilized fusion,and the social assistance legal institutions should response positively the relative legislative concept and methods which the world has achieved the common understanding on the base of using initialively the legislative experiences in the developed country and the ones where the relative institutions reach a better performance for reference.

政治文明背景依赖方面，由统治者怜悯、恩赐到自己权利的享有和诉求，本身就体现出无产阶级为建立社会救助法律制度所付出的努力和奋斗，因此社会救助法律制度完全具有自己存在、发展和壮大的政治体制空间；经济体制背景依赖方面，经济基础决定上层建筑的朴实真理具体而实在地发挥着自己的演进逻辑，市场经济条件下贫富差距会继续扩大，贫困居民对社会救助法律制度的依赖会进一步加强，其社会救助权诉求也将会变得日益强烈；文化传统背景依赖方面，大同社会、均贫富理想、鳏寡孤独废疾者皆有所养的追求等中国源源流长的救济思想都已经沉淀为一种浓厚的文化传统，儒家思想主张实施仁政，倡导养民、恤民，民本思想在中国文化中占据着根深蒂固的地位，社会救助法律制度安排回应了中国传统文化脉络的延续；国际化背景依赖方面，观念的同化和主流价值观的流播，使文明的互融速度加快，社会救助法律制度需要主动借鉴发达国家以及相关制度具有较好绩效国家的立法经验，积极回应全球已达成共识的社会救助立法理念和方法。

Firstly, an empirical approximation model of stochastic programming is obtained by replacing the probability measure of original program with empirical probability measure. Sequentially, the constrained stochastic programming is transformed into an equivalent unconstrained stochastic programming. Finally, using the epi-convergence theory, the almost everywhere upper semiconvergence of optimal solution set of empirical approximations for stochastic programming is obtained.
