本文以中國1997~2003年中央政府對地方政府之淨移轉支付為研究對象，運用量化之研究途徑，分析中國近年來中央政府資源分配之財政目標變化，以及影響此財政目標之主要因素。依據本文實證結果分析顯示，在1997~2003年這段期間，中國中央政府的財政資源分配方式由過去以穩定社會環境、發展整體經濟為主要目標，轉以均衡各地情況為主，於此同時，影響此財政資源分配模式之主要因素為區域政策之轉折，並推論中國區域政策的產出與執行，並非如一般所論，僅是領導人安定環境、攏絡民心的口頭宣示和空頭支票。 / Through examining the transfer payment from China’s central government to provincial government, this study seeks to discover the logic of financial resource allocation in China. It goes on to compare the modes of financial transfer in different years to see whether China has devoted more resources on income redistribution, and if so, which factor make that happen. My findings suggest that China does adjust the logic of resource allocation, shifting from pro-growth to pro-balance through these years. And, the key that trigger such change is the modification of regional policy instead of reshuffle of top leadership.

本文建立小型開放經濟體系的VAR模型，利用符號限制法（Sign Restrictions）認定財政政策衝擊，評估台灣財政政策的總體經濟效果。符號限制法係利用對衝擊反應函數做符號限制的方式認定財政衝擊，對關心的變數如：實質GDP、民間消費、民間投資、貿易收支等變數對財政政策衝擊的反應則不設限制，讓資料來回答。本研究參酌Mountford and Uhlig（2009）及Ho and Yeh（2010）的方式認定總合供給衝擊、總合需求衝擊、貨幣政策衝擊、政府支出衝擊以及政府收入衝擊。研究結果發現，政府支出衝擊對民間投資短期會產生排擠效果，中長期（二十季）則有提振的效果。政府支出衝擊引發短期名目利率上漲，國外資金流入，實質有效匯率上升，貿易收支因而下跌。政府支出衝擊對於實質GDP一開始有正向效果，但排擠效果短期會使實質GDP下跌，一旦政府支出帶動中長期民間投資後，對實質GDP有正向效果，但並不顯著。 政府收入衝擊短期對實質GDP、民間消費、民間投資有正向效果，中長期的效果為負。若以政府支出衝擊細項來看，政府消費支出衝擊對實質GDP有顯著提振的效果，政府投資支出衝擊對於實質GDP的助益十分有限。

本文的研究目的為，在一個含有房屋及房屋相關貸款的動態隨機一般均衡模型的架構中，比較貨幣政策、財政政策以及總體審慎政策對於房屋價格及房屋相關貸款的穩定效果。本文建構一個經濟封閉體系，其中包含三種不同家計單位、商品生產部門、房屋建商、資本生產部門，並且由政府部門制定相關政策；此模型的特色為，不同家計單位中的借貸行為、名目價格僵固性以及透過房屋價格抵押貸款的限制來刻劃金融摩擦。我們考慮了一般緊縮貨幣政策、提高財產稅率以及緊縮貸款價值比；本文發現，在三種政策中，對於抑制房屋價格以及降低住房貸款對國內生產毛額的比例，財政政策及總體審慎政策比起緊縮貨幣政策擁有較好的效果。 / The main purpose in this paper is to compare the effect of monetary policy, fiscal policy and macroprudential policy on housing price and housing related loans using a micro-based dynamic stochastic general equilibrium (DSGE) model with housing and housing related loans. We equip a closed economy model with three types of infinitely-lived households (patient households, impatient households and renters), a goods firm, housing and capital producer and a government sector. The model features borrowing and lending between patient and impatient households, nominal rigidity in goods price and financial friction in the form of collateral constraints tied to price of house. We consider the contractionary monetary policy by raising the interest rate, fiscal policy by increasing property tax rate and the macroprudential policy through tightening the loan-to-value (LTV) ratio. We find that among these three policies, in terms of dampening the price of housing and lowering the loan-to-GDP ratio, raising the property tax and lowering the LTV ratio outperforms the contractionary monetary policy.

本文主要目的在嘗試建立一個包括總需求、總供給，預期和不確定因素的開放總體經 濟模型，並探討在此模型下的最適資本移動政策，最適外匯政策及最適財政和貨幣政 策。 過去的文獻中，在求最適資本移動政策時，並未加入預期，總供給面及不確定因素， 本論文第一部份將探討加入這些因素後，最適資本移動係數的選擇。此外根據以前的 文獻，在探討最適外匯政策時，均假定資本是完全移動的，本文第二部分將解放此假 設，探討滿足損失函數（Loss function ）––即所得之變異數為最小的最適外匯政 策，同時可以證明出資本完全移動下之結論只是本文結論中的一個特例而已。本文第 三部份將利用所建立之模型探討在各種不同匯率制度（固定、管理及浮動匯率）下之 最適財政及貨幣政策，並希望能找出最適之政策搭配。

日本經濟自1990年起，由「日本第一」落入「流動性陷阱」，而陷入長達10多年的不景氣，主因是日本股市及不動產市場重挫，企業向銀行貸款所提供之擔保品價值下滑，卻因在低利率時代已過度借貸，又經營不善面臨虧損，發生償債困難，一旦財務有所改善，只想提前償還貸款，而無增加貸款意願，故稱為「資產負債表的衰退」（Balance Sheet Recession）。整體經濟景氣蕭條，國內需求不振，亦使振興經濟之寬鬆貨幣政策無法達到預期效果。 日本資產泡沫的破滅使銀行體系的逾放問題日益嚴重。日本政府為了加強銀行體系的健全性，實施金融改革（Big Bang）。使原本以傳統存、放款業務為主的銀行，在面臨國際化浪潮時，也能同時經營證券、保險業務，並將新金融商品引進日本。並由隸屬於內閣府的金融廳(Financial Services Agency)來監督日本銀行及證券業務，負責金融檢查及金融法規企劃業務，落實金融與財政分離之原則。但日本金融業務日益多元化，及衍生性金融商品日趨複雜，對金融監理機關之專業能力，形成新的挑戰。以上所述為日本國內的經濟與金融問題。 至於日圓對外幣的匯率方面，由於日圓利率偏低，套利交易(carry trade) 盛行。投資人趁著日本央行維持低利率之際，借入低成本的日圓資金，然後換成利率較高的外幣轉戰國際市場，追逐收益較高的資產，同時賺取利差、匯率及資產升值的價差，使日圓匯率的走勢疲弱，也造成全球金融市場的波動。 本論文的分析包含： ㄧ、日本經濟不景氣問題剖析：股市及不動產資產泡沫化 二、日本金融危機形成原因：資產價格下跌，影響抵押品價值，企業償債能力變差，故使銀行不良債權增加。 三、日本總體經濟近況（GDP、CPI、失業率的變化）及經濟復甦後日本央行貨幣政策的改變 四、日本金融市場如股市、房地產市場及日本政府債券（JGB）市場的分析及展望。 五、探討日本銀行業獲利能力、不良債權問題、資本適足率以及銀行業股價指數的變化。 六、根據台灣以及日本最近的發展對金融監理單位及銀行業提出應有的改革與建議。 / The Japanese economy fell into a “liquidity trap” in 1990. Due to the stock market and real estate market plunge, the deep recession has lasted for over 10 years. The bursting of asset bubbles caused the balance sheets of enterprises to become weaker and weaker. All companies hoped to reduce their debt to banks if they were profitable. They had no intention to reinvest any more. So it was called - Balance Sheet Recession. Even though the Bank of Japan adopted an easy monetary policy, the financial system remained vulnerable. With the bad debt of commercial banks increasing, the NPL (non-performing loan) problem has been a major concern for city banks and regional banks. Japan's "Big Bang" reforms radically altered its financial marketplace. The barriers separating banks, securities, and insurance companies were lowered. The Financial Services Agency replaced Ministry of Finance to oversee banking, securities and exchange and insurance in order to ensure the stability of the financial system. As for financial business diversified and derivative products complicated, there were many great challenges facing the financial regulatory authorities. During the past decade, the yen carry trade has become a target for many investors or speculators. Traders using this strategy attempt to capture the difference between the interest rates of two currencies. Taking USD/Yen for example, they borrowed the cheaper yen and invested in U.S. Treasuries yielding a higher interest rate. It causes the depreciation of Japanese Yen and increases the volatility of financial markets. This essay describes Japanese financial crisis, Japanese monetary policy, stock market, and real estate market. Besides, I analyze the profitability, capital adequacy, and non-performing problems of Japanese banks. Finally, I give my personal opinions on Taiwan and Japan’s banking industry.

思及當前捉襟見肘的財政窘境，無可避免地，債台高築的臺灣實陷入飲鴆止渴般以債養債之無限迴圈中，導致政府政策效能不彰、社會福利運作生弊亦無可厚非；於『公共債務法』之財政規範下，臺灣業已瀕臨法定舉債門檻，故不論是對短期政府支出之排擠、扭曲性稅率之稽徵抑或對長期經濟成長的斲傷，皆是身為中華民國國民真正惶悚不安之所在。 職是之故，本研究係採用一納入政府財政部門及貨幣當局之擴充『實質景氣循環模型』，藉以Sidrauski（1967）所提出的貨幣效用函數為出發點，將實質餘額引進理論模型，並透過計量操作捕捉實證期間起於西元1971年第一季迄至2007年第四季之政府政策函數，過程中，我們不難發現政府購買性支出及稅率皆存在相當的持續性，且對政府未償公債餘額之高低作出某種程度的反應。亦即，若政府實施公債融通政策，俾使期初公債餘額較高之際，則本期甚或往後各期的政府支出將遭受抑制和排擠，尤有甚者，政府勢必擬以提高未來稅率以茲挹注該債務之還本付息所造成的財政缺口；是以，本研究著眼於引進公債餘額對政府支出及稅率存在反饋作用下，財政政策與貨幣政策之總體效果及各總體變數之動態調整過程的風貌。即便公債發行或賒借為政府提供一財務週轉工具以裨益財政政策保有更靈活之彈性，然據模型所產生的結果顯示，就長期而論，政府必須維持一穩定之未償公債餘額，即公債水準具備『均數復歸』性質，而該財政目標係透過削減未來政府支出、調整扭曲性稅率及鑄幣稅融通政策方得以達成預算平衡，準此，該設定將造成公債融通之減稅政策對經濟體系具有實質效果，『公債融通』管道亦『非中立性政策』，從而傳統『李嘉圖等值定理』於本模型中無法成立。 就政策面層次而言，本研究試圖放寬『反饋法則』與政策係數之設定，以檢視透過不同程度之政府支出、稅率甚至貨幣供給途徑的改變來平衡因增加公債發行所造成的財政赤字，對經濟體系之長短期效果有何迥異處；是文亦藉由衝擊反應函數分別探討於政府支出增加、減稅措施及貨幣擴張之下，政策的傳遞機制與各總體變數之動態性質，顯然地，就高債務比率前提下，當政府戮力於刺激景氣而欲積極實施立竿見影的總體經濟政策之際，卻常因狃於急效而欲速不達，非但政策效果有限，亦可能使體系落入更為不景氣的田地，從而，財政惡化不啻為經濟危機的導火線也就不言而喻。再者，貨幣政策對體系之實質變數具有一定程度的作用，是故，本模型於短期內無法一窺『貨幣中立性』之堂奧，唯長期始得以復見。總括言之，政府亟須奉『健全財政』為圭臬，擬定政策時更得戒慎恐懼，並適切權衡利弊得失，以茲裨益有更具信心的經濟表現。 此外，本研究亦透過『效準』實驗以評估模型『配適度』之良窳，即便於反覆疊代法下，該模擬表現係瑕瑜互見而不盡完美，卻也大抵符合景氣循環之『典型化特徵』；然就實質景氣循環模型所為人詬病之勞動市場一隅而論，引進公債之反饋法則下的財政政策操作，無疑地改善了傳統工時與工資率動輒高度正相關之本質，從而獲致相對較低之理論相關係數，亦朝實證資料所呈現工時與工資率存在幾近零相關甚或低度負相關之表徵更邁進一大步。 / With current financial difficulties beyond government capability, it is inevitable that the already deep-in-debt Taiwan opted for momentary relief by paying debt through debt financing and ended up in an infinite loop, causing spiral-down performances in government policies and faulty operations of social welfare instruments. Taiwan has been on the verge of reaching the statutory upper limit of debt financing according to “The Public Debt Act” regulations and all nationals are becoming anxious about such impacts as crowding out of short-run government spending, levying of distorting taxes, and damages on long-run economic growth. To better understand the debt’s impacts, this research uses the “Real Business Cycle Model” extended by taking government treasury agency and monetary institution into account. Starting with Money In Utility Function (MIUF) as proposed by Sidrauski (1967) to introduce real money balance into the theoretical model and, in the process of econometric manipulation, to detect empirical governmental policy functions in the period between the first quarter, 1971 and the fourth quarter, 2007, it is not hard to discover that there are considerable persistence in both government purchases and tax rates, with manifestation of certain degree of responses to the total amount of outstanding bonds the government has yet to pay. In other words, a governmental bond financing policy designed to render high initial bonds outstanding tends to cause suppression and crowding out of government spending in current and even later periods. Furthermore, the government is bound to plan on raising taxes in the future in order to cut financial deficit gap caused by paying back the principles and interests of the debt. Therefore, this study focuses on presenting the macroeconomic effects of fiscal policies and monetary policies, as well as the dynamic adjustment processes of macroeconomic variables based on the impact of feedback effect of bonds outstanding on government spending and tax rates. Even thought public bonds issuance or debt financing serves as a governmental fiscal instrument for financial turnover to ensure flexibility of fiscal policies, our model shows that the government should, from a long-run perspective, maintain a stable amount of bonds outstanding. Put in a different way, the level of bonds outstanding shows “mean-reverting” characteristics which rely on future government spending cut, distorting tax adjustment and seigniorage financing policy to achieve balance of budget. As a result, such setup would cause the bond-financing backed tax deduction policies to create practical effects on economies and, as the bond financing instruments are “Non-Neutrality” policies, would render the “Ricardian Equivalence Theorem” invalid in our model. In the policy aspect, this study tries to relax both “feedback rules” and setup of policy parameters for investigating the differences between long-run and short-run effects on the economy by different degrees of changes in government spending, tax rates and even money supply channels which are used to balance the fiscal deficit caused by increased bond issuance. This article also studies, through the impulse response function, the policy propagation mechanism and the dynamics of key macroeconomic variables under the situation of government spending increase, tax deduction and monetary expansion. It is obvious that the government, in the case of high debt ratios and when making all endeavors to spur economy by implementing macroeconomic policies aimed for instant results, is accustomed to seeking quick fixes only to achieve very limited effects, sometimes even to drive the economy into further recession. It is therefore evident that fiscal degradation could lead to economic disaster. Moreover, as the monetary policies have certain degrees of influence on real variables of the economy, this model will not be able to clearly analyze the “neutrality of money” in such a short period of time. The effect will only reveal in the long run. In summary, the government should keep “sound finance” as the highest guiding principle and be extremely cautious in formulating policies in order to weigh all pros and cons discreetly, thus help to achieve a benefiting economic performance that generates more confidence. Furthermore, this study assesses “goodness of fit” of the model through a “calibration” experiment. Although the simulation results show, under recursive method, intermingled good and poor occasions that are beyond satisfaction, they generally agree with the “typical characteristics” of business cycles. However, in the aspect of long-criticized labor market of the real business cycle model, the fiscal policy operation under feedback rules with introduction of public debts for sure has greatly improved on the conventional intrinsic property of high correlation between labor hours and real wage rates, by delivering a relatively low theoretical correlation coefficient, which is a big step towards the empirical results of almost zero or even weakly negative correlation between labor hours and real wage rates.
