Abstract: China's tourism industry has become the most active one in tertiary industries. This paper analyzes the economic growth effects of tourism, and makes a comprehensive evaluation on the domestic tourism development strength in provinces and cities by means of factor analysis method. The results show that there is two-way causal relationship between economic growth and domestic tourism, economic development level of regional tourism in general has great consistency with the overall level of regional economic development, and the scale of tourism economy plays a very important role in tourism economic performance.

Abstract: The former researches referring to inflation and real estate prices concentrated mainly on the stock prices rather than the real estate prices. Owing to the enlarging ratio of real estate industry in national economy with each passing day, as well as the overheating real estate prices in recent years, the relationship between real estate prices and inflation is particularly vital to the monetary policy making for the monetary authorities. According to the test analysis of data from 2001 to 2009, it is found that real estate prices is Granger Cause of inflation while inflation is not the Granger Cause of real estate prices in this paper. Through the Effects of Wealth, Credit and Tobin, real estate prices drive the growth of social consumption and investments and expand the total social demand which possess an positive effect on inflation; nevertheless the rising of real estate prices causes the rising of currency for real estate purchasing, which, under the circumstance of that currency supply remains, will inevitably bring about the reduction of currency for other consumption and investments and restrain the total social demand which would mean a suppression of continuous rising of prices of other commodity and labor service. All these show that real estate also has a negative effect on inflation. The cancellations between the two effects make the long-term influence real estate bearing on inflation is not obvious. The experimental results indicate that when the price of real estate rises 1%, inflation only rises 0.058%. Consequently, a strict controlling of the amount of money issued is the key factor for keeping the over rapid rising of real estate prices from leading to inflation.

Abstract: This text finds that the concentration ratio of automobile industry market in China overall takes on rising trend, which is based on the calculation of automobile industry market's concentration ratio in China between 2001 and 2008, the characteristics of market structure is similar to oligarch competition since 2008. According to industrial organization theory, people come up with the theoretical model of automobile industrial performance, including the variables of industry concentration ratio, profit ratio, research and development intensity, product differentiation, entry barriers and so on. Empirical evidence shows that the relation between profit ratio and the concentration ratio of automobile industry market is remarkably positive, while it is negatively related with research and development density and product differentiation. It also finds that the key point to improve profit ratio of China's automobile industry is enhancing central technical level.

Abstract: This paper analyzes the current development of industry clusters of the industrial parks in Jiangxi. It is found that most of the industrial parks are in the stage of agglomeration, others are in the transitional phase from agglomeration to cluster and the remaining, namely about the one-third industrial parks, are still in the concentrated phase. There is a large gap between the development of the industrial parks in Jiangxi and the requirements of industry clusters, which is embodied in the fact that the industrial structures converge, the growth of industrial chain is incomplete and the supporting system of production is imperfect. Finally, the countermeasures are proposed from the perspective of the government to promote the development of industry clusters of the industrial parks in Jiangxi. These countermeasures mainly are to make the industrial orientation clear, to plan a good industrial layout, to develop the industrial parks based on the mechanism of industriy clusters, to actively explore appropriate development models, to strengthen the construction of industrial supporting system and to create an innovation environment for industry clusters in the industrial parks.

Abstract: Biomedical titanium alloys can be used for replacement and repair surgeries of human hard tissues. In recent years, the new b type titanium alloys with low elastic moduli and excellent biocompatibility have been developed by choosing low cytotoxic elements. Furthermore, new type of porous titanium alloys can lower elastic modulus effectively and contribute to the ingrowth of tissues. The present research status of new b type titanium alloys and porous titanium alloys have been introduced in this literature, the future research trend has also been discussed.

Abstract: This article discusses the correlation between market structure and value GetCapabilities of major procedures of the PV industry, from the results we can find: As the number of enterprises involved in four procedures of the industrial chain increases, the degree of monopoly of market structure in all procedures are becoming more and more weaker, increasing the level of competition, which resulting in decreasing order of the corresponding distribution of profits, demonstrated as a "inverted pyramid" structure. Market structure of value chain in every procedure determines its ability to obtain the profits. That the industrial organization of PV industry can be explained by the SCP paradigm of Harvard School.

Abstract: A mathematical model is created, and the algorithm is designed according to the fuzzy clustering. The main indices of the soy sauce samples are detected, and the data are analyzed using fuzzy clustering. As a result, many classes including different soy sauce sample can be obtained, and the quality within the same class is similar. The mathematical model and algorithm provide a method to identification the soy sauce. And in the others, it provides a new method to evaluate the quality of the soy sauce.

Abstract: Vibration analysis of steel truss bridge is required by promotion in the speed of train. The train and the truss girder bridge are coupled together as one composite system. Truss girder bridge is idealized as an assemblage of finite truss element. The vehicle space vibration model of two-stage suspension is used, which has 26-degrees of freedom. The equations of the train and truss girder bridges time varying system are set up by using the principle of total potential energy with stationary value in elastic system dynamics and the“set-in-right-position”rule for forming structural matrices. This method is more convenient than the finite elements. The vibration responses of train and bridge are calculated when the trains pass through a truss girder bridge at different speeds. The results show that the bridge has sufficient lateral and vertical stiffness.

Abstract: Under the contemporary development of economic development of economic globalization, the advantages that large-scale enterprises have in technology and scale make the presence of large-scale multinational group of companies have become a symbol that can measure the comprehensive strength and status of a nation. It is imperative to develop the large-scale multinational enterprises for their important and active role in the competition between nations, especially for private enterprises in China to improve their international competitiveness.

Abstract: With Chinese automobile industry in its infancy, the model of its development will play a leading role to remain invincible in an increasingly competitive market. Based on the status analysis of automobile manufacturing development, this paper adopts the fundamental principles of symbiosis theory to dissect the symbiotic relationship between Chinese automobile manufacturing enterprises and small and medium-sized supporting enterprises and demonstrate its symbiotic form in detail, referred to enterprise network, and thus put forward the symbiotic mode suited for Chinese automobile manufacturing enterprises and small and medium-sized supporting enterprises.
