    [[abstract]]本研究為探討網路搜尋對股票期貨與現貨之間價格發現的影響程度。本文運用向量自我迴歸模型和向量誤差修正模型檢定股票期貨價格與現貨價格之價格發現,以研究期間為2010/9/1/~2015/12/31之日成交值前30名的股票期貨和現貨為研究標的,探討股票期貨價格與現貨價格之間的價格領先關係,之後將Google搜尋量指數(SVI)分別以虛擬變數(D1、D2、D3)加入模型中,探討高搜尋量(D1、D2)以及低搜尋量(D3)對股票期貨價格與現貨價格的價格發現的影響。實證結果顯示,在資料尚未加入虛擬變數和在加入低搜尋量後,它們的關係都為現貨價格領先股票期貨價格,但兩者間價格發現的比例變動不大,然而在加入高搜尋量後,價格發現的比例卻銳減一半,從上述的結果來看,高搜尋量反而導致價格發現比例下降,這樣的現象是受搜尋量中的雜訊所致,因此,搜尋量本身對市場的價格發現影響程度並不大,亦即代表搜尋量與市場效率的關聯性較低。[[abstract]]Thisstudydemonstratestheimpactonpricediscoverybetweenstockfuturesandspots,resultingfrominternetsearching.Ifirstutilizethevectorauto-regressionmodelandthevectorerrorcorrelationmodeltoexplorepricediscoverybetweenstockfuturesandspots.Inmyexperiment,fromSeptember1,2010toDecember31,2015,Ifocusonthethirtystockfuturesandspotswiththehighestdailytradingvaluesandthelead-lagrelationshipbetweenspotandfuturesprices.IevenaddtheGooglesearchvolumeindex,withdummyvariables,D1,D2,andD3,denotinghightolowsearchvolume,tomymodelthatexploretheeffectonspotandfuturesprice.TheempiricalresultshowsthatspotpricesalwaysleadsfuturespriceswhetheraddingdummyvariableD3ornot.Then,afteraddingdummyvariables,D1andD2(highsearchvolume),therateofpricediscoveryisdramaticallyreducedto50%.Sincethisisduetooutlierwithinhighsearchvolumeindex,Imaysaythatthesearchvolumehaslittleinfluenceonmarketprice.Furthermore,Iconcludethatsearchvolumehaslowcorrelationwithmarketefficiency

    担载于zrO2上的ru3(CO)12-fE(CO)9混合簇的红外光谱表明,ru3(CO)12以ru(CO)2O2表面络合物存在.混合族在真空中随温度升高而发生脱羰基作用,500℃左右羰基完全脱掉;以Al2O3为载体者其羰基不易脱除,升高温度出现多种羰基带.混合簇中的fE2-(CO)9极易脱羰基.担载混合簇在Ar气中进行TPdE时,低温时以脱羰基为主,高于150℃时发生表面歧化反应而生成CO2;在H2气中,低温时仍以脱羰基为主,高于150℃时发生表面加氢反应而生成CH4.混合簇的脱羰基和表面反应能力与ru/fE比及载体有关.担载混合簇在CO加氢反应中以ru(CO)2O2和分散fE存在,还出现-CHX多种表面物种.The decarbonylation and the surFace reaction of mixed cluster Ru3(CO)12-Fe2 (CO)9 supported on ZrO2 or Al2O3 have been studied by IR spectroscopy and TPDE-GC technique.IR spectra show that the Fe2(CO)9 in the mixed cluster easily desorbs its carbonyls and disperses on the carrier in Fe Form.on ZrO2, the carbonyl bands of Ru3 (CO)12 disappear and the characteristic bands corresponding to Ru (CO)2O2 appear, and the carbonyl bands Fully vanish at about 500℃ in vacuum.On Al2O3, the carbonyl bands are hardly removed.TPDE-GC rasults show that the weaker carbonyls in the mixed cluster are desorbed at lower temperature, and the stronger ones are disproportionated to CO2 in Ar and hydrogenated to CH4 in H2 at higher temperature.It is also Found that the TPDE character of the supported mixed cluster is similar to that of supported Ru3 (CO)12 cluster.During CO hydrogenation at 250℃, three C- H stretching bands corresponding to various-CHxspecies and the characteristic carbonyl bands of Ru (CO)2O2 surFace complex are observed by in silu FT-IR spectroscopy.国家自然科学基金;厦门大学固体表面物理化学国家重点实验室资
