Numerical Simulation On Blasting Cavity And Experimental Study Of Grouting For Supporting In Soil

Along with the global economic integration degree deepening, the various countries economy relation is more and more tight. Therefore, the various countries are also facing the opportunity and the challenge what the opening brings. The international payment balance is most complete record that reflected a country foreign economical transaction and the economical opening developmental strategy and the policy, and is worth more attention and more thorough research.Since 1990s, our country national economy rapidly develop, the checking account favorable balance and the capital and the financial account favorable balance's scale has increased in large amount for successive years, which brings our country international reserve in large scale growth, enhances the government internationally to pay off the strength, promotes our country economy to develop, raises the lives of the people level and so on a series of advantage. But which also causes our country to suffer the trade friction to increase, the import resources degree of dependency raises, the trade condition worsening and so on a series of inevitable questions. The double favorable balance of our country is whether the revenue and expenditure structure can maintain, which stage can maintain, which stage can't maintain, and how to deal with the question, is twining Chinese Political circle and the academic circles continuously.The former international payment balance research embarked from the overall situation, but has neglected the international payment balance constitutive question. This article draws up from international payment balance theory neglecting structure obtaining, and divides five chapters that analyze the double favorable balance of our country may maintain and the improvement countermeasure. First chapter is the introduction. First section has analyzed the selected topic background and the research significance, pointed out the double favorable balance of our country in the short-term (5 to 10 years) may maintain, and the internal structure of double favorable balance can have the change along with our country economy development: The cargo trade surplus scale will be slow drops, the service trade deficit scale will drop even transfers the jot favorable balance, the investment income trade deficit scale also rises the small scale, but the foreign direct investment scale had the drop still to maintain the favorable balance, the negotiable securities investment and other investment trade deficit scale drops; Long-term the double favorable balance of our country cannot maintain.

Second chapter is the summary of correlation theories. First, second limits the concept of international payment balance structure and the international payment balance organization's maintenance separately, and proposed the international payment balance structure's maintenance divides into the international payment balance organization in short-term to be possible to maintain and the international payment balance organization may maintain for a long time. Third section was limiting the double favorable balance and in the concept foundation commenting correlation theories. Third chapter to double favorable balance of the present situation has carried on the analysis. First section, from structure obtaining, has analyzed between various levels account and the secondary account relations. Second section, third, fourth using the graph analytic method separately from our country international payment balance and the foreign exchange reserve overall situation, the checking account structure situation, the capital and the financial account structure situation three aspects summarizes the condition of the double favorable balance in detail. Fourth chapter analyzes that the double favorable balance may maintain. First section gave the model of double favorable balance to be possible to maintain. Second section analyzed our country in this model foundation from the checking account and the capital and the financial account diagnoses the double favorable balance to be possible to maintain in the short-term. The third tubercle from the model as well as the maintenance of the double favorable balance's the weak foundation, and the maintenance of the double favorable balance's the price greatly analyzes the double favorable balance not to be possible to maintain for a long time. Fifth chapter, from the three facts of the international payment balance adjustment policy, the foreign trade foreign capital policy, and the industrial policy, realizes our country international payment balance structure to be possible to maintain the countermeasure for a long time, and emphasized emphatically the promotion industrial structure promoted the special operational policy measures, the transformation of economy growth way, the expansion needs.
