[Abstract]:The economic cycle is used to represent a phenomenon of the cycle of economic expansion in the process of the cyclical economic contraction of economic operation, and we usually divide the economic cycle into four stages of recovery, prosperity, recession and depression, The economic cycle can be divided into two aspects: the theoretical research and the empirical study. The purpose of the theoretical study is to explore the reason of the formation of the economic cycle by establishing a theoretical model based on a certain hypothesis, and to point out the change trend of the economic operation according to the analysis result of the model; The main task of the empirical study is to describe the economic cycle and give a more accurate measurement of the state of the economic operation according to the economic indicators that can be used. This paper is an empirical study of the economic cycle. Since the outbreak of the global economic crisis in 2007-2009, there has been a wide range of problems related to the prediction of the turning point of the economic cycle Note: The determination of the turning point of the economic cycle is a very important issue for families, businesses and investors, as their current decisions on consumption, production and investment depend on their future economic outlook hope. For bankers and policymakers of the central bank, an accurate and reliable prediction of the economic situation is conducive to the implementation of appropriate and pre-emptive administration The paper first defines the benchmark index, that is, the agreement synthetic index published by the national statistical office, and uses the B-B method to determine the turning point for the reference index, and then, based on the outline of the foreign advanced index system, the paper makes use of the time difference correlation analysis and the peak-to-valley correspondence method. In this paper, we have carried out a lot of screening work on the leading indicators used in this paper, and 12 leading indicators were selected from different fields, namely, the growth of crude steel, the increase of the output of chemical fertilizer, the growth of the output of the automobile, the increase of the output of pig iron, the growth of the cement output, and the number of the end of the month of the month of the month of the month of the month. The increase of the growth rate, the completion of fixed assets investment, the increase of the number of new start-up projects in the fixed assets investment in the current year, the cumulative year-on-year growth of the export volume, the reversal of the CPI, the growth of the stock volume and the sales of the commercial The data period used herein is 1999.1 to 201. 3.5. According to the need of the empirical study of the article, we have selected 12 leading indicators, and the principal component analysis method is based on the correlation matrix to solve the factor load, and the contribution rate and the cumulative contribution corresponding to it are calculated. The rate and the characteristic value, so that the factor load matrix gets more explicit economic meaning, the initial factor load array is loaded by the maximum variance method. the four factors are finally extracted, namely, the main upstream product yield factor, the liquidity and the investment factor, the demand factor and the money, In this paper, based on the four factors and the method of probit model in different forms, the turning point of the economic situation is put forward based on the consensus synthesis index published by the statistical bureau. In this paper, the prediction results of two models of static probability model and dynamic probability model are compared, and when the single-variable static probit model is used for estimation, it is found that the prediction result is not reliable, so it is further constructed The model of the built-in variable. Although the explanatory variables included in the two different form of probit models are the same, the lag phase of each explanatory variable is different, and we select each explanatory variable in different models according to the highest McFadden R2 The results of the prediction in the samples show that the four factors extracted by using the antecedent index can predict the fluctuation of the economic cycle in China, and the dynamic probability model is better than the static probability model, and we also set the probability gates of 0.5 and 0.25 respectively. Limits, with the result that, when lower probability threshold values are used, the prediction of the recession is increased, but at the same time an error is added The average absolute error (MAE) and the root mean square error (RMSE) are used for the prediction of the outside of the sample. The results show that we use the prediction model established by the four factors It is reasonable and effective. The results of the out-of-sample prediction of the dynamic probability model are also excellent. In the static probability model, and a different probability threshold is used to predict the percentage of the decay month, it is found that the probability threshold value of 0.25 can be more accurate for the recession than the probability threshold value of 0.5 Based on the analysis of the influence factors of the FAVAR model on the economic form, the empirical results show that: (1) The positive impact of a unit in the production of the main upstream product in the current period will affect the economic situation of our country. There is a positive response, which can last about a year or so; (2) the impact of liquidity and investment factors on the economic situation is also positive, and when the amount of money is increased or the investment of fixed assets is increased, it will be The economy has a promoting effect, and the promotion rate is longer than that of the main upstream product, for about two years or so; (3) the inhibition of demand factors has an inhibitory effect on the economy, so the demand factor is Jinan has a stimulating effect, so increasing demand can promote economic development; (4) the wealth effect has a good effect on China's economy A positive impact. But overall, the biggest impact on economic shocks is liquidity and investment, that is, money The main innovation of this paper is the following three points: (1) This paper takes the first index extraction factor as the corresponding (2) In this paper, a multi-variable probit model is used for prediction. The results of the prediction are compared in this paper. (3) The FAVAR model of the comparative front edge is used to analyze the four factors.
