大西部的开发与美国的现代化

西部大开发对美国历史的影响是全局性的。它不仅涉及6.5倍于美国宣布独立时的领土和2倍于东部的联邦成员,而且其过程几乎贯穿于美国的整个成年时期。大批处女地的拓殖及三大农业“王国”的建立,极大地增强了美国的经济基础:五大湖重工业区的建立,则使美国的产业升级,从而加快了美国工业化和现代化的进程。另成千上万独立的农场主在西部的成长,不仅直接为1861年爆发的内战提供了战斗力量,也为19世纪末和20世纪初的“进步主义”改革准备了社会基础。但美国的西部大开发也引发了大量只顾眼前利益而不顾长远利益的短期行为,其建设性和破坏性相伴而行。直到西奥多.罗斯福总统上台时,才采取以有序开发取代无序开发的新型开发模式。

China’s Western Development Strategy for Modernization Drive

The Western Development Strategy(WDS)is a key aspect of China’s coordinated regional development strategy and effort to build a modern country.The world is undergoing profound changes that have not been witnessed in a century.This paper discusses the WDS’s importance in regards to China’s modernization drive and the great rejuvenation of the Chinese nation.First,this paper identifies the WDS’s mission to improve people’s livelihood in China’s western regions,promote common prosperity for the Eurasian continent,and support the green transition of China’s and Eurasian energy economic and environmental systems,and safeguard ecological security in Asia at large.Second,this paper suggests that the key to the WDS is to reshape the geographical layout of economic activity in the western regions to avoid inefficiency.Specifically,China should develop a compact geographical layout of economic activity in the western regions,introduce a unique competition strategy,as well as find solutions for coordinated regional development based on key river basins.Finally,develop smart internet and inland free ports within the western regions.

Key technologies for the construction of the Xiluodu high arch dam on the Jinsha River in the development of hydropower in western China

Hydropower development in China is concentrated in the country's western regions.Among all the rivers in China,the lower course of the Jinsha River contains the richest hydro-energy resource,and therefore,4 mammoth hydropower plants are under construction on this particular section of the river at Wudongde,Baihetan,Xiluodu,and Xiangjiaba.The water-blocking structures of the hydropower facilities at Wudongde,Baihetan and Xiluodu are all arch dams of around 300 m high.In view of changes in the geological conditions at the foundation of the Xiluodu dam on the riverbed after excavation started,the designs of expanding foundation surface excavation and dovetailing the dam body and foundation rock on both upstream and downstream sides were introduced,allowing the arch dam and foundation to fit each other and improving the stress conditions of the dam body and foundation.By dividing the dam body into various concrete sections,the dynamic properties of concrete were adequately adjusted to the distribution of stress in the dam body.In addition,the use of the most optimal concrete material and mixture ratio allowed thermodynamics of concrete to satisfy the requirements of the strength,durability,temperature control and crack prevention of the concrete.Moreover,rigorous temperature control measures were introduced to prevent harmful cracking,thus enhancing the integrity of the arch dam.Furthermore,sophisticated construction machinery,scientific testing methods,and sound construction techniques were employed to ensure the uniformity and reliability of concrete placement.The "Digital Dam" for the Xiluodu project,which is based on the theory of total life cycle,has supplied strong support for construction process control and decision-making.

Influence of moisture content on shearing strength of unsaturated undisturbed quaternary system middle pleistocene

The unsaturated undisturbed quaternary system middle pleistocene loess,a typical unsaturated soil,often occurs in the implementation of western development strategy.To obtain the shearing strength characteristics of this unsaturated undisturbed loess,based on the analysis of mineral composition,the triaxial shear test of undisturbed quaternary system middle pleistocene loess under different moisture contents is conducted with the specialized triaxial instrument for unsaturated soil.The test results show that the mainly mineral composition of undisturbed quaternary system middle pleistocene loess is quartz and albite.Under the same confining pressure,the matric suction increases with the decrease of moisture content.The smaller the moisture content,the larger the matric suction;the higher the moisture content,the lower the matric suction.Under the same moisture content,the matric suction increases with the confining pressure and reaches a maximum when the confining pressure is 100 kPa,and then decreases with the increase of confining pressure.This phenomenon is closely related to the grain contact tightness of soil mass under high confining pressure.According to the triaxial test of loess,the sample of loess experiences 4 stages from loading to failure:1) compaction stage;2) compression stage;3) microcrack developing stage;4) shear failure stage.The test sample is of brittle failure(weak softening)under low moisture content and confining pressure.With the decrease of matric suction and the increase of consolidated confining pressure,the stress-strain curve changes from softening type to ideal plastic type.In the shearing strength parameters of unsaturated undisturbed loess,the influence of moisture content on internal friction angle is small,but that on cohesive force is obvious.Therefore,the shearing strength of unsaturated undisturbed loess is higher than that of saturated undisturbed loess and varies with the moisture content.

China＇s Regional Policy Scenarios for 2011-2015 Period

In pursuit of more balanced regional development, China should base its regional policy during the period of the 12th Five-Year Plan on the principle of fairness, and tailor it to the specific characteristics of needy areas and development priority zones. The country ＂s master plan of developing the western region, revitalizing the northeast, supporting the rise of central China, and upgrading the east should continue.

The Drive to Develop China＇s West： An Inclusive Perspective

Since the launching of the western regional development program in 1999, the Chinese government has implemented a series of policy measures related to finance, taxation, investment, banking, and other related fields. This combination of policies has stimulated socioeconomic growth and ecological improvement in China＇s western regions and has effectively curbed the runaway gap between the east and west, even causing the gap to begin shrinking gradually. However, it should be noted that the development gap between China＇s eastern and western regions remains significant, as demonstrated by the west＇s low level of industrial^commercial development, local governments＇ limited capacity to provide public services, and endemic rural poverty. Thus, achieving the targets outlined in the western regional development program remains a challenging task. In the future, China＇s western development program should emphasize a higher standard of living and coordinated, inclusive growth across regions.

An Evaluation on the Effects of the Policy of the Great Campaign of Western Development of China in the First 10 Years Based on the Kuznets Regional Inverted-U Theory

In order to reduce the regional differentials or narrow the gap in economic development between eastern and western areas and prevent the intensification of contradictions resulting from the regional inequality during the development process, the government of China launched the Great Campaign of Western Development （GCWD） in 2000. In this paper, we will evaluate the effects of the first 10 years＇ GCWD and use the latest Chinese annual data from 1978 to 2010 to investigate the problem of regional differentials in the development process, evaluate the effects of GCWD policy and test whether there is a regional Kuznets inverted-U curve in the regional development of China. The result shows that there are both good and bad news： the good news is that the inverted U-shaped curve of absolute differential between eastern and western areas finally emerges （the previous studies showed that the inverted-U curve did not appear and the differentials between eastern and western areas became worse） and the bad news is that the differential is in the first half of the inverted U-shaped curve in our choice of time span （1978-2010）, that is, it is still in the situation of deterioration, and the turning better point will emerge in 2025. Although the western areas have benefitted from GCWD, the absolute gap has been still widened. To narrow the gap, the western areas should accelerate the industrial development and the government should adjust the policy and make more efforts to support the development of the industry in the western areas, especially cultivate and support the development of the western characteristic and advantageous industry rather than just supporting the construction of infrastructure in the western areas.

Discussion on Cultivating the Idea of the Western Rural Market Economy

Along with the deepening of the economic system reform, the quickening of our country＇s steps joining WTO, and the enlarging of the discrepancies among different regions, how to promptly change the sense of the western rural areas to resolve the ＂the three problems connected with agriculture, peasants, and countryside＂ and utilize the market economy regulation and taking market as the direction has become the initial problem of the economic development in western countryside in order to push the smooth implement of the western development. This thesis starts with the essence, function, and other influential factors of this idea, systematically elaborates the current idea characteristics of each stratum in western countryside, discovers the reason that the sense of western rural areas falls behind the times, and definitely puts forward with new idea characteristics which is suitable for the economic development of the western rural areas, and also offer some policy suggestions on how to realize this change of the sense in western rural areas.
