The analytical method of total resource reallocation effect is an evolution of the analytical method of the factors of economic growth. Since the marketization reform in China in 1978, market mechanism has played a more and more important role in resource allocation, and Chinese economy has developed greatly, which is called "the Chinese Miracle". This paper analyzes the economic growth in China from 1978 to 2004 with the analytical method of total resource reallocation effect. The result shows that the annual growth rate of total resource reallocation effect was 0.2%, which was 5.1% of the comprehensive productivity and 0.21% of the gross output growth, i.e. the total resource allocation played a weak role in the economic growth in China. When analyzing it in Chenery's multinational model, we find that Chinese comprehensive productivity growth rate was higher than that in all the income phases of the model, but the total resource allocation effect was obviously lower than that in all the income phases of the model. It indicates that the total resource allocation in China has a great potential, and that to accelerate marketization reform is one of the important issues for Chinese economic development.

The combination of fiber optics with nano-structure technologies and sensitive thin films offers great potential for the realization of novel sensor concepts. Miniatured optical fiber sensors with thin films as sensitive elements could open new fields for optical fiber sensor applications. Thin films work as sensitive elements and transducer to get response and feedback from environments, in which optical fibers are employed to work as signal carrier. This article presents some research work conducted at the National Engineering Laboratory for Optical Fiber Sensing Technologies in recent years. Concrete examples are： Pd/WO3 co-sputtered coating as sensing material for optical hydrogen sensors shows robust mechanical stability and meanwhile good sensing performance; TbDyFe magnetostrictive coating directly deposited on fiber Bragg grating （FBG） demonstrates its possibility of miniature optical magnetic field/current sensors, and 40-pm shift of the FBG wavelength happens at a magnetic field order of 50 mT.

An improved glucose sensitive membrane(GSM)is prepared by immobilizing glucose oxidase(GOD)onto a mixture of silica mesocellular foams(SiMCFs)and SiO2 nanoparticles(SiNPs)and then trapping it in a polyvinyl alcohol(PVA)*** membrane is coated onto a gold-glass sheet to create a surface plasmon resonance(SPR)sensor.A series of experiments are conducted to determine the optimized parameters of the proposed *** a GSM with a component ratio of SiMCFs:SiNPs=7:3(mass rate),the resonance angle of the sensor decreases from 68.57°to 63.36°,and the average sensitivity is 0.026°/(mg/dL)in a glucose concentration range of 0 mg/dL‒200 mg/*** a GSM with a component ratio of SiMCFs:SiNPs=5:5(mass rate),the resonance angle of the sensor decreases from 67.93°to 63.50°,and the sensitivity is 0.028°/(mg/dL)in a glucose concentration range of 0 mg/dL‒160 mg/*** data suggest that the sensor proposed in this study is more sensitive and has a broader measurement range compared with those reported in the literature to date.

Fiber Bragg grating (FBG) array is a powerful technique for quasi-distributed sensing along the entire length of sensing fiber with fast response and high precision. It has been widely used for temperature, strain, and vibration monitoring. In this review work, an overview on the recent advances of FBG arrays is conducted. Firstly, the fabrication methods of FBG array are reviewed, which include femtosecond laser system and online writing technique. Then, the demodulation techniques for FBG arrays are presented and discussed. Distributed static sensing can be performed by demodulating wavelength shift of each FBG, while phase demodulation techniques with low noise are employed for dynamic vibration sensing. Simultaneous distributed dynamic and static sensing system based on FBG array is also outlined. Finally, possible future directions are discussed and concluded. It is believed that the FBG array has great development potential and application prospect.

Tibet is located in the high Qinghai-Tibet plateau. Surrounded by tall mountains,it, thus,forms a relatively complete inland geograph-ical unit,and is largely sealed off from the rest of the country. The climate and infrastructure condi-tions of the high plateau impede communication be-tween the Tibetan market and the national market. The development of Tibet is facing difficulties. On the one hand,the“invisible hand”of the market cannot fully play its role in promoting Tibet’s de-velopment;and,on the other hand,the sole reli-ance on the“visible hand”of the state administra-tion for the socio-economic development of Tibet lacks strong market support. In 1994,the Central Government’s Third Tibet Work Forum established a formal system regarding assistance for Tibet’s de-velopment. It is ,“taking responsibility by divid-ing the region into zones, providing assistance through complementary counterpart relationships, which were periodically rotated”. This became a method for handling this difficulty. The purpose of providing assistance through complementary coun-terpart relationships to Tibet was to promote Tibet’s self - development capability, and develop a“hematopoietic”system for socio -economic de-velopment.

取消农业税后中国农村治理结构的改革与完善是必须研究并加以解决的重大问题。本文的研究表明,取消农业税等于拆除了收费平台,农村公共产品供给、乡村债务化解和乡镇财政运行等重大社会经济问题便尖锐地摆在人们面前,从而使得乡村治理方面的矛盾日益凸现出来,倒逼着乡村治理结构改革;而实践把乡镇改革推到改革的最前沿,乡镇成为农村治理结构的关键环节;乡镇改革的最终目标是打破现有框架结构基础上的重建农村治理结构,即实现乡镇自治;要完全一步走到乡镇完全自治模式,是有一定难度的,必须有一个过渡期,在过渡期内实现乡镇政府职能转换。
