數字水印是一種新的數字媒體保護技術,它是將特定的信息(如版權信息、秘密消息等)嵌入到圖象、語音、視頻等各種數字媒體中,以達到版權保護等目的,同時,這種信息對宿主媒體的影響不足以引起人們的注意且有特定的恢復方法,此信息對非法接收者應該是不可見的,本文主要對數字水印的一般框架,靜止圖象dct系數的理論容量,圖象水印的嵌入和檢測,數字媒體防篡改以及數字水印的攻擊等問題進行了研究,提出了兩個新的水印算演算法。The model of this paper explores the links between the following factors and the credit rationing in china. the change of banks " attitude to credit risk may lead to credit rationing ; banks give much more emphasis on the trade cost and the payable value of collateral, which may give rise to credit rationing ; the decreasing of asset price during economic stagnation produces credit rationing ; the bias of banks " objective function from the maximization of profit and the transformation of the function relating to the reform of the financial system cause credit rationing ; if different parts of the whole markets are not integrated, the credit in the part with low capital return ratio will be rationed. during economic recession, banks tend to ration the credit in the high - risk market ; the removing of interest ceiling will narrow down the interest spread of deposit and credit at least during a period, which may strengthen credit rationing ; meanwhile, the vulnerable borrowers, including small and middle - sized enterprises, will get more credit from banks even though they have to pay a higher interest rate
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。At last, we have some advises about how to bellowing human capital gini coefficient : region a should let the high rank human capital to flow out, cultivate the middle rank human capital, support and ensure the low rank human capital and make the structure of college education more rational. region b should reduce human capital gini coefficient basing on improving the level of people been educated. region c should strengthen the support of nine years duty education, develop the career technique education and whole life education, reduce the human capital being
