Construction of Social Credit System and Commercial Reform of Development Bank of China
Credit investigation system is an important part of construction of social credit system. With the economic development,credit investigation system plays increasing role in preventing credit risk. China Development Bank,focusing on China’s features,with the help of development finance,has developed construction of credit system,improved systematical defects,and contributed greatly to the construction of credit investigation and social credit system.
Channel estimation based on multiple-model adaptive technique
A new channel estimation method based on the multiple-model and adaptive technique was proposed. This method covers the state changes of unknown channels through designing the dynamic channel model bank, uses the dynamic program to detect model changes, and uses the model changing technique to estimate the channel parameters, so it combines several simple estimation algorithms to one channel estimator in the varying channel environment, which has the high robust performance in a big channel range. The results of the simulation experiment shows that the new method has the advantage comparing the adaptive channel estimator.

Petrogenesis and implications of the volcanic rocks in Zabuye salt lake area,western Lhasa terrane,Tibet,China
The postcollisional potassic and ultrapotassic rocks have been found recently in southern Tibetan plateau,which are important clues in studying the deep processes since India collided with Asia.The volcanic rocks located in the east bank of Zabuye salt lake in western Lhasa terrane were dated to be ~16 Ma,with an area of ~ 400 km2.The volcano erupted in ~0.45 Ma with an eruption rate of 0.26×10-3km3/year.Three types of rock were found in the Zabuye volcanics.Type one(~16 Ma) are ultrapotassic trachyan-desite,with lower SiO2(55%-58%),high Fe2O3,MgO,and TiO2.Type two(~27 Ma) are shoshonitic phonolite and trachyte.Typethree are shoshonitic and ultrapotassic trachyte(SiO2=59%-64%) and rhyolites(SiO2=69%),with high Sr lower Y adakite-affinity.The rocks,as a whole,show enrichment of light rare earth elements(REEs) and large ion lithosphile elements(LILE),and are low in some high field strength elements(HFSEs).The Sr-Nd-Pb-O isotopic composition of the Zabuye rocks differed from the typical ultrapotassic rocks in southern Tibet.Instead,they show similar nature to the rocks from the northern Tibet geochemical province.The Zabuye rocks imply that,they originated from partial melting of different depth of the lithospheric mantle and thickened lower crust that caused by the thinning process in southern Tibet.
Study on Screening Identification and Properities of Debranching Enzyme Producing Bacteria
Objective: The bacteria of producing debranching enzyme were screened from CICIM-CU,identified,and studied the characteristics of debranching enzyme. Method:Screened debranching enzyme producing strain,identified taxonomic status,determine debranching enzyme properties by iodine solution coloration plate and 16S rDNA sequence alignment method.Result:45 strains which can produce debranching enzyme were screened from 4005 strains and the bacteria bank capable to produce debranching enzyme was set up finally.The results showed that the debranching enzyme from CICIM B272 and CICIM B1-30 performed the maximal activity at 70℃,pH 6.0 and 60℃ pH 5.5,respectively.The enzyme had thermostability between 30℃ and 70℃ and pH stability from 4.5 to 8.5.The enzymes were strongly activated by Li+,Na+,K+,Mg2+,Mn2+,whereas inhibited by Cu2+,Fe3+ and EDTA.Mn2+,Ca2+ significantly increased their thermostability,respectively.The kinetic constants of the enzyme was obtained,their Km for amylopectin were 352.883mg/mL and 4.5814mg/mL,Vmax were 30.03 mg/min·mL and 0.4575 mg/min·mL,respectively.Conclusion: The difference in the enzymatic property of debranching enzyme was significant between different genera.
Financial Crisis Impact on Bank Credit Risk
China’s enterprises,especially SMEs,have been seriously affected since the outbreak of the financial crisis.In order to ensure the healthy development of SMEs,the central government and all levels of local governments and commercial banks have introduced a number of measures to help SEMs to finance.Some of the measures will virtually increase the commercial banks in SME credit risk in the implementation process.According to the background of the current financial crisis,this paper analyzed the credit risk of commercial banks that the policy brought and how to control the credit risk from different angles.
The Choice of Financing Mode for Technological Innovation
In the fields of technological innovation,firms and banks have incentives to lower down risk and pursue short-term profit,which makes bank’s loan a fundamental mode in financing firms’ incremental innovation.The mature leaders in an industry are more likely to choose this kind of funding.As for new comers,they prefer long-term investment for radical innovation with both high risk and high returns in order to get a firm foothold and more market share,venture capitalists in the stock market can effectively provide funds for their need.Those startups that own new technology or plan to implement radical innovation are more likely to use venture capitals.This paper will analyze these two financing modes theoretically.
On Impulse Effect of Short-run Economic Shocks on Zhejiang Export
Under the centralized influence from a series of domestic and oversea factors:slow-down of world economy owing to American subprime mortgage crisis,declining in foreign demand,rising price of domestic producing materials,RMB appreciation and so on,Zhejiang export faces the declining trend on growth rate.By using impulse-response function based on VAR theory and setting up a shock-response model of the main short-run effect factors on Zhejiang export,this paper uses monthly data to analyze empirically the impulse effect of these factors on Zhejiang export and their contribution through variance decomposition technology.The result shows that bank loan and income of trading partners have a notable impact on Zhejiang export.Basic methods dealing with these issues are enhancing international economic cooperation for getting through financial crisis together,dispersing market risk,increasing financial support for medium and small sized private-run export enterprises and expanding exports appropriately.
Scientific and technical innovation: the prime driving force for economic development
This year, the World Bank invited several experts and scholars led by two Nobel Prize winners to analyze 11 countries whose economy grew fast in the past years, which resulted in the release of the Growth Report. The report said that the main five factors led to the 7% growth rate of per-capita income of the 11 countries during the past 20 years conclude economic openness, Macro-economic Stabilization, high save, market-oriented economy and Government Promotes. In the Z-Park forum 2009, Mr. Lin Yifu, Senior Vice-President and Chief Economist of the World Bank, told us something about this, the following is what he said.
The Re-examination of PPP in China—-Based on ESTAR and ARB-STR Models
Based on monthly Renminbi-Dollar real exchange rate data since Apr 1994,this paper studies the nonlinear mean reversion adjustment of PPP towards its long-run equilibrium employing ESTAR and ARB-STR models which contain the second polynomial time trends serves as the empirical proxy for B-S effects.The B-S effects in the models show that the real equilibrium exchange rate depreciated continuously during 1994-2000,and appreciated continuously since 2001,but the appreciated tendency has been slow down recently.The impulse response function analysis shows that the bigger the shocks,the faster the mean reversion speed of the real exchange rate,and the adjustment behavior is unsymmetrical when faces to positive or negative different shocks,and the mean reversion speed is faster when Renminbi is undervalued than it be overvalued.Also,due to the different informative mechanism of Renminbi exchange rate and the frequent intervention of central bank,it has longer half lives of shocks compared with those in west developed countries.Lastly,some policy suggestions are proposed briefly.
