論文的模型探討了下列因素和中國信貸配給現象之間的聯系：商業銀行對信貸風險的態度變化，在辨別和控制信貸風險上開始投入大量的成本，這一過程會導致信貸配給；商業銀行對與法治環境相關的交易成本和抵押品清償價值的日漸關注會導致信貸配給；宏觀經濟緊縮時期資產價格下降會導致信貸配給；商業銀行經營目標函數偏離利潤最大化，近幾年金融業改革過程使商業銀行目標函數發生變化，這一變化過程可能導致信貸配給；在市場分化的條件下，收益水平低的市場會遭受信貸配給；在經濟下滑時期，商業銀行尤其會對高風險市場配給信貸；利率市場化使商業銀行的存貸利差至少在一段時間內縮窄，利差縮窄可能加重信貸配給的程度：在利率市場化條件下，弱勢借款者，包括中小企業，遭受信貸配給的程度可能得到緩解，但支付的貸款利率水平將會升高。Expanding the system ' s hamiltonian to a real symmetric matrix in an appropriate orthogonal basis vector and then diagonalizing it, we get the energy spectrum of the system and calculate the energy level spacing distribution function and the spectral rigidity. then we study the statistical character of the energy spectrum under the changing of magnetic field intension and find that the system ' s motion transfers from regular to chaos gradually
