In the digital era, the information value of online prices, characterized by weak price stickiness and high sensitivity to economic shocks, deserves more attention. This paper integrates the high-frequency online inflation rate into the dynamic Nelson-Siegel (DNS) model to explore its relationship with the term structure of interest rates. The empirical results show that the weekly online inflation can significantly predict the yield curve, particularly the slope factor, while the monthly official inflation is predicted by yield curve factors. The mechanism analyses indicate that, due to low price stickiness, online inflation is more responsive to short-term economic conditions and better reflects money market liquidity, thereby having predictive power for the yield curve. Specifically, online inflation for non-durable goods and on weekdays shows stronger predictive power for the slope factor. The heterogeneity in price stickiness across these categories explains the varying impacts on the yield curve.

The study reveals that the COVID-19 crisis has had a strong but one-off negative impact on the hedge fund industry. It also shows that during the new coronavirus pandemic, the main components of the hedge fund industry achieved only partially their main investment goal, i.e. they as a whole provided a hedge of the investment risk but did not produce higher than the market return in the conditions of a growing capital market. In this situation, due to the relatively stable М&A market, the Event-Driven Risk Arbitrage strategy was undoubtedly most successful, followed by the Emerging Markets, the Global Macro and the Long/Short Equity strategies. The worst performance was reported for the Fixed Income Arbitrage strategy due to the currently overvalued bond markets and to the expectations for higher inflation rates in the countries with developed capital markets.

利率工具作为央行货币政策的重要组成部分，也是实施货币政策的主要手段之一。中央银行根据货币政策实施的需要，适时地运用利率工具，对利率水平和结构进行调整，以此影响社会资金供求状况，调节微观经济主体的具体经济行为，进而实现既定的货币政策目标。 自2008年经济危机以来，中国人民银行多次利用存款准备金率和利率工具对国家宏观经济进行调节，特别是2010年以来为了应对由之前过度宽松货币政策导致的严重通胀形势，央行5次提高存贷款基准利率，12次提高存款准备金率至21.5%的历史高位。尽管如此，但是国内利率水平依然处在低位，实际利率持续为负。存准率过度提高导致货币供给大幅减少，利率水平维持低位使货币需求上升，这样扭曲的货币政策导致了我国宏观经济在各方面的失衡，并且遭到了来自各界的非议。究竟利率工具的宏观经济调控效果如何呢，为何央行不愿意使用价格型货币政策工具——利率进行调控呢？虽然目前存准率工具的使用次数要远多于利率工具，但是随着今后利率市场化改革的深入推进和我国金融体制的开放改革，今后利率调控工具将会成为央行调节宏观经济运行节奏的主要手段。因此，研究利率政策调控对宏观经济的影响将有助于我们明确利率调控的效果、认清宏观经济变化的原因，在利率市场化的背景下也能够为央行制定科学的货币政策提供决策依据。 本文是按照“回顾改革以来利率政策的调整历史→实际利率变动对主要宏观经济目标的实证检验→影响利率政策效果的原因分析→增强利率调控效果的政策建议”的基本思路，展开全文的分析讨论。在对改革开放三十年以来的利率政策历史回顾分析的基础上，采用定性和定量分析相结合的方法，对利率变动与经济增长率、通货膨胀率以及城镇登记失业率进行实证检验，得出不同阶段实际利率的变化对不同宏观经济目标的影响。在此基础上得出全文结论，实际利率与经济增长率的关系从正相关逐渐发展为负相关，与通胀率则是显著的负相关，而实际利率与城镇登记失业率则呈现很弱的相关性。然后具体分析影响我国利率政策调控宏观经济效果的原因，主要包括利率管制政策、金融市场发展建设及经济主体行为三个方面。最后在前文讨论的基础上提出增强利率调控效果的政策建议，主要包括放松利率管制、继续推进利率市场化改革、完善货币市场发展建设、加强央行宏观调控能力等方面。 Interest rate policy is an important component of monetary policy，also the one main instruments of monetary policy implementation．According to the People’s Bank of China monetary policy needs in a timely manner，use of interest rate tools，include the level of interest rates and interest rate structure in order to affect the supply and demand of funds，micro-economic regulation of the main acts，and to achieve monetary policy objectives． After 2008 world economic crisis, the interest rate and deposit-reserve ratio has been changed more times to adjust China’s macroeconomic. Especially since 2010 to cope with the serious inflation caused by the prior overly lax monetary policy, the central bank raised the benchmark deposit and lending interest rates 5 times and 12 times to raise the deposit reserve ratio to 21.5% highs. In spite of this, but the domestic interest rate level is still low, the real interest rate is negative for longtime. Money supply is greatly reduced by the excessive increase of deposit reserve ratio, and monetary demand rises because the level of interest rates remains low. Such distortion of the monetary policy in our country makes our macro economy imbalance in all aspects, and has received criticism from all walks of life. How about the interest rate tool of macroeconomic regulation and control effect, why the central bank is not willing to use price monetary policy tools -- interest rate regulation? Although the deposit-reserve ratio has been changed more than the interest rate, but with the market-oriented reform of interest rate and financial system, interest rate regulation will be the main method of macroeconomic adjusting control. So studying on macroeconomic effects of real interest rate would help us to be more clearly knowing the results of the interest rate policy and understanding the reasons for changes in the economy. Furthermore，in our country, the interest rate is not fully market-oriented, the study is also helpful for authorities to make the correct monetary and interest rate policy. “Review the history of interest rate policy adjustment from Reform and Opening up→the empirical test of real interest rate on the main macroeconomic goals→the reasons analysis which have influence on the effects of interest rate policy→the policy recommendations which make interest rate regulation more effective" This is the main train of thought of this paper, around which expand the analysis and discussion. Based on the review of the history of interest rate policy after Reform and Opening-up from 1980, used the combination of qualitative and quantitative analysis, through analyzed the effects of real interest rates which impacted on the three macroeconomic objectives, include the GDP growth rate、the inflation rate and the urban registered unemployment rate, we get the result that in different stages, the interest rate policy have different impacts on economic objectives. At the last, we get the whole conclusion and analyzed the reasons which caused interest rate policy to be ineffective on the macro economy. Finally, according to China’s financial market, this paper gave some reform suggestions which can make interest rate policy to be more effective on macro economic adjusting control.

It is well documented that bond excess returns are time-varying and that they can be explained by predetermined risk factors. This paper builds a theoretical model to forecast excess returns on treasury bonds in the context of China’s unique monetary system. Empirical evidence shows that bond excess returns in China are highly predictable when compared to those in developed markets. Further investigation suggests that the predicted components are primarily driven by the inflexible term structures of official interest rates set by China’s central bank.

中央银行独立性问题在现代宏观经济研究特别是货币政策研究中备受关注，其与宏观经济指标的相互作用很大程度上决定着货币政策的运行效果。就此问题，本文首先介绍了西方学者对央行独立性的不同定义及研究的理论基础，随后从理论和实证两个角度分析中央银行独立性同宏观经济运行之间的关系，最后本文得出如下结论：中央银行独立性与通货膨胀之间的关系比较明确，与其他变量之间的关系仍不能明确界定；中央银行独立性的提升确实能有效降低通货膨胀率，但是抑制通货膨胀不能单独地成为支持中央银行独立性的理论基础；是否提高中央银行独立性应该结合其与物价、就业、经济增长的关系； The Central Bank Independent (CBI) issue has drawn more attention in macroeconomic research, especially is in the monetary policy research .To a large extent, it’s interaction with macroeconomic goals (price, economic growth, employment) mutually plays a remarkable role on the effect of monetary policy. On this question, this article first introduced the western scholar’s different definition on central bank independent and the theoretical basis of it. Then, we analyses the relationship between Central Bank independence and macroscopic economic performance theoretical and empirical angle. Finally we drawn draws the following conclusions: The relations Between the Central Bank independence and the inflation is quite explicit, but we are not clear about it’s relation with other variables such as growth、employment、deficits; Increasing Central Bank independent can effectively reduce the inflation rate, but “cut down” inflation cannot alone become the support for Central Bank independence; Whether or not to enhances the Central Bank independence should take in account it’s relations with the price, the employment, the economy grows; we should care about the “stationary” of variable when dealing with time-series data, otherwise the conclusion maybe less in accuracy and credibility;
