對於一般自然壟斷產業,產權改革和引入競爭是克服公有壟斷低效率的兩種常用的手段;然而對于銀行這種特殊產業,特別是在中國,由於信息不對稱以及行政性壟斷的存在,因而並不能簡單地通過產權和競爭來達到這一目的。After 1989, the increase of demand slowed down and facing the complexion of low degree of industrial concentration of product market and financial strain of medi um and small - sized enterprises caused by the circulating trap of " credit squeeze - - - bad loan ", the advantageous enterprises " " wallow in money ", specifically, those listed companies that could finance from the stock market, began to take predatory pricing strategy in succession and tried to enlarge market share and obtain high return by squeezing medium and small - sized enterprises out of the market after 1998, the vicious circle of deflation and " credit grudging " of banks in product and credit markets, overcapacity, the difficulty of retreating of loss - incurring enterprises in some industries from the market for institutional reasons and over - competition in some industries, led to the incessant decrease of enterprises " global income, persistent increase of rate of debts and constant rise of ratio of bad assets of banks, which further intensified the vicious circle of deflation and " credit grudging " of banks
如在改革開放初期,在產品市場需求旺盛和信貸市場預算軟約束的情況下,各類企業的最優決策就是採用高負債、高擴張的「負債的有限責任效應」策略來搶占市場並獲得高回報; 1989年以後,需求增速開始放緩,面臨產品市場產業集中度較低和信貸市場「信貸緊縮-不良貸款」循環陷阱導致的中小企業資金緊張的局面, 「錢袋鼓鼓」的優勢企業(尤其是那些可以通過股票市場融通資金的上市公司)紛紛採用掠奪性定價策略,試圖通過把中小企業擠出市場來擴大市場份額並獲得高收益; 1998年以後,產品市場和信貸市場形成了通貨緊縮和銀行「惜貸」惡性循環的狀況。產品市場上部分行業生產能力嚴重過剩,且由於體制等原因導致虧損企業無法退出,因此這些行業中出現了過度競爭的現象,企業總體收益的不斷下滑、負債率不斷提高以及銀行不良資產率的持續上升,又進一步加強了通貨緊縮和銀行「惜貸」的惡性循環。Multibeam base - station smart antennas are discussed in this paper. we analyze the outage probability of mobile communication system suffering both fast fading and shadowing by means of statistical propagation model, and contrast the case that adopt multibeam smart antennas to the case that adopt omnicase. the results emulated by computer show that the outage probability of mobile communication system will diminish as the increasing of the number of beams using smart antennas no matter when suffering a single co - channel interfence or six ones
