Auto financial analysis of listed companies and test methods


SPSS11.0 standardized data series, based on the sample adequacy, the common factor of the size and the variable degree of practical significance, by deleting the 27 joint degree smaller or less variable with the overall association. To obtain satisfactory results. KMO and Bartlett'S from sphericity test can be seen, KMO test value of 0.719, the original samples are more adequate; Bartlett'S sphericity test probability is 0.000, reject the hypothesis that the correlation coefficient matrix of linear correlation between variables, not a unit matrix, can be applied to factor analysis. Screening method using principal component factor of a common degree of extraction, and then extracted according to factors Stone Figure 5 factors the eigenvalues, representing the percentage of their accumulated value of variance (Table omitted), the solutions of these five factors reflect all information. From the rotated factor loading matrix (abbreviated) can be seen, the first principal factor is determined mainly by the 4,5,8,14,15, these four variables the amount of information reflected in the total amount of information 47.348 %, reflecting the company's profitability; second factor composed of the 1,6,7 and 9. These four variables reflecting the amount of information of 18.263% of the total amount of information, reflecting the company's profits and earnings, is the closest relationship with investors factor; third factor constituted by the 10,11 and 12, reflecting the enterprise asset management; 2,3 formed by the fourth factor, reflecting the interests of shareholders are more concerned about the assets; fifth factor determined mainly by 13, reflecting asset growth conditions. At this point, the 15 variables reduced to five factors independently of each other. According to the share of factor scores and the ratio of total variance explained, we can calculate the 50 listed companies ranked position. Because of space variance explained 93.021% of the total variance can be more fully restricted, only listed the top 4. The total evaluation score of three, the results of tests derived from factor analysis to test whether the business enterprise ranked stock in secondary market transactions are consistent with the performance, the paper selects the accumulated stocks that 5O Price (based on 2002 January 4 opening date and December 31,[link widoczny dla zalogowanych], 2002 closing price calculated) Ranking By comparison, using non-parametric rank correlation test on the two test sequences. Using the Spearman rank correlation SPSS11.0 test, two-tailed test probability of approximately 0.0017, less than 0.01,[link widoczny dla zalogowanych], reject the null hypothesis and accept the alternative hypothesis,[link widoczny dla zalogowanych], that is, a significant correlation between the two series, derived from the annual financial index factor score ranking and then trading in shares of the same rank Price. IV, Conclusion and Analysis (1) the size advantage is gradually emerging, large-scale enterprise group growth momentum. In the top of the rankings on the parent company of several listed companies, all with the restructuring of the automotive industry in 2002 related to: FAW Toyota, Dongfeng and Nissan, Shanghai Auto and the characters are different at different levels of business cooperation. (2) vehicle type 2002 operating results of listed companies in general better than the parts listed companies,[link widoczny dla zalogowanych], driving cars into the automobile industry the major driving force. Among the top ten of the only Only six are vehicle class. First, with the domestic economy is growing,[link widoczny dla zalogowanych], per capita income rising, and the country has been introduced to encourage personal automobile consumption credit (mainly cars) and the relevant policy, the private car as a means of transport was evident warming. Second, the impact of tariff reduction is far lower than the consumer expected. As the ultimate auto parts tariffs of 10%. Less than 25% of vehicle levels, the accession to the WTO on the vehicle industry is less than the impact of auto parts industry. (3) the performance of mini-buses are more prominent, State Information Center statistics show that in 2002 production and sales of minibuses in the overall model output ranked first, accounting for 22.36%, 2O (O-year long-term gains, to achieve a robust sustained growth.
