【摘要】:研究目標(biāo):構(gòu)建采購(gòu)經(jīng)理指數(shù)PMI和生產(chǎn)者價(jià)格指數(shù)PPI結(jié)構(gòu)分量間的傳導(dǎo)機(jī)制。研究方法:使用PMI和PPI同比序列進(jìn)行集合經(jīng)驗(yàn)?zāi)B(tài)分解(EEMD)得到固有模態(tài)序列作為觀察信號(hào),采用特征矩陣聯(lián)合近似對(duì)角化算法(JADE)提取獨(dú)立信號(hào)分量序列并通過(guò)游程判定法重構(gòu)出不同頻率的結(jié)構(gòu)分量,最后進(jìn)行Granger因果檢驗(yàn)。研究發(fā)現(xiàn):PMI和PPI重構(gòu)出的高中低頻三個(gè)結(jié)構(gòu)分量分別反映短期波動(dòng)、中期波動(dòng)和長(zhǎng)期波動(dòng)。Granger因果檢驗(yàn)表明,高頻分量中PPI和PMI互為因果關(guān)系,傳導(dǎo)時(shí)長(zhǎng)為1期;中頻分量中PMI是PPI的因且先行4期;低頻分量PPI是PMI的因且先行10期。研究創(chuàng)新:將時(shí)頻分析方法 EEMD-JADE聯(lián)合算法引入經(jīng)濟(jì)領(lǐng)域。研究?jī)r(jià)值:為經(jīng)濟(jì)量化調(diào)控政策提供導(dǎo)向和理論依據(jù)。
[Abstract]:Research objectives: to construct the transmission mechanism between the purchasing manager index PMI and the producer price index (PPI) PPI structure. Research methods: ensemble empirical mode decomposition using PMI PPI sequence (EEMD) and an intrinsic mode sequence as the observation signal, the characteristic matrix of joint approximate diagonalization algorithm (JADE) to extract the independent component signal sequence and reconstruct the structure through the run method of determining the components of different frequency, finally, Granger causality test. It is found that the three structural components of high and low frequency restructured by PMI and PPI reflect short-term fluctuations, medium-term fluctuations and long-term fluctuations, respectively. The Granger causality test shows that PPI and PMI are mutually causation in high-frequency components. The transmission time is 1 periods. In the intermediate frequency components, PMI is PPI and the first 4 phases; the low frequency component PPI is PMI, and the first 10 phases. Research Innovation: the time frequency analysis method EEMD-JADE joint algorithm is introduced into the economic field. Research value: provide guidance and theoretical basis for the economic quantitative regulation policy.
