How to calculate the competitiveness index

1. 1、 Statistical methods and models (1) principal component analysis (PCA)
1
2. Calculate the barycenters of the initial K classes, and then calculate the distance from the sample to the initial K class one by one. If a sample is closest to its original class, it will still be in the original class, otherwise it will be moved to the nearest class, and the barycenters of the class losing the sample and the class receiving the sample will be recalculated, That is, the center of gravity of each class is recalculated as the condensation point of the class
3. Recalculate step (2) until all samples can not move, or if all the new condensation points in a certain step coincide with the previous old condensation points, the calculation process will be terminated< Secondly, principal component analysis is used to analyze the comprehensive competitiveness of 13 cities in Heilongjiang Province, and 19 indicators are selected as the factors to reflect the comprehensive competitiveness of 13 cities in Heilongjiang Province, which are agriculture, forestry, animal husbandry and fishery x1; mining (x2); Manufacturing (x3); Proction and supply of electricity, gas and water (x4); Construction (x5); Transportation, warehousing and postal services (x6); Information dissemination, computer services and software instry (X7); Wholesale and retail (x8); Accommodation and catering (x9); Finance (X10); Real estate (X11); Leasing and business services (X12); Scientific research and technical services and geological survey instry (x13); Water conservancy, environment and public facilities management (x14); Residential services and other services (x15); Ecation (x16); Health, social security and social welfare (x17); Culture, sports and entertainment (x18); and; Public administration and social organization (X19). Data source: Heilongjiang statistical yearbook 2012 (see Table 1)
1. Initialize the original data
2. Establish the correlation coefficient matrix R of variables

4. Given the principal component, the cumulative contribution rate of the first two eigenvalues has reached 96.228%. According to the first two eigenvalues, the first two principal components are (as shown in Table 2 and table 3):
we find that: in the first principal component, the coefficients of each index are larger, so the first principal component reflects more information about the original index, which is defined as comprehensive component. In the second principal component, only the coefficient of the second term is larger than that of the other terms, so it is defined as mining instry component
5. Calculate the corresponding comprehensive score according to the principal component score of each region, and the calculation formula of the comprehensive score is:
from table 3, we can see that the ranking of each principal component is not the same. Harbin, Qiqihar, Daqing and Mudanjiang are the top of the first principal component ranking, indicating that they have a high comprehensive level in 19 indicators. Jixi, Qitaihe, Harbin, Shuangyashan and Hegang, which ranked the top in the second principal component, showed that they had a good foundation in mining instry
if the comprehensive score is greater than zero, the comprehensive competitiveness level is above the average, that is, Harbin, Daqing, Qiqihar, Mudanjiang and Jiamusi; If the comprehensive score is less than zero, it means that the comprehensive competitiveness level is below the average, namely Suihua, Jixi, Shuangyashan, Heihe, Qitaihe, Yichun, Daxinganling and Hegang
in terms of comprehensive scores, Harbin ranks first in comprehensive competitiveness. This is consistent with the fact that the region is the capital of Heilongjiang Province and the economic, political and cultural center of Heilongjiang Province. Secondly, Daqing, Qiqihar, Mudanjiang, Jiamusi and Suihua are in the second place of comprehensive competitiveness. Finally, in the third category are Jixi, Shuangyashan, Qitaihe, Heihe, Yichun, Daxinganling and Hegang. The conclusion drawn by principal component analysis is basically consistent with the current comprehensive level of each city< The results are as follows:
the results show that the classification results of principal components are correct and reasonable< Conclusion this paper uses principal component analysis and cluster analysis to analyze the comprehensive competitiveness of 19 indicators in 13 regions of Heilongjiang Province. The results show that the conclusions of the two methods are basically the same, which shows the correctness of our method. Therefore, the government should make scientific planning according to the results of the evaluation of the level of urban competitiveness. Thus, while vigorously developing the resource advantages of each city, the capital and technology should be inclined to the general cities, so that the competitiveness of the weaker cities can be improved in varying degrees, and then the coordinated development of each city in the province can be promoted.

2. Competitiveness index refers to the coefficient of trade balance. The closer the competitiveness index is to 100%, the stronger the competitiveness is; On the contrary, the closer to - 100%, the weaker the competitiveness
trade competition index refers to the ratio of a country's net export value of a certain proct to its total import value and export value. If the ratio is positive, it means that it is a net exporter. If the ratio is closer to 1, it means that the international competitiveness is stronger.

3. Ponzi scheme is a kind of fraulent investment operation. It uses investors' own money to pay investors in return, or new investors' money to pay old investors, rather than the money earned by the company itself. When there are not enough new investors to join, the Ponzi scheme will collapse, and the final investors will suffer

4. When you talk about affinity, I think you need to pay more attention to it. I don't know whether you have many friends and whether you like to make friends or not. I have many friends and it's easier for me to make friends personally. At first, when people thought I was lonely, I knew the reason very well. I didn't want to integrate into them at all. Frankly speaking, I didn't want to integrate into them, Therefore, naturally, I won't talk much. Later, I wanted to make friends with you. So, I made some efforts and tried. Let's not say for a moment. What I want to say here is that if I want to have a good relationship, the key is not affinity, but your attitude and whether you have this heart. I hope you can come up with this mentality first

secondly, you have realized that the tone of your voice is a big problem, because one of my friends is too similar to you. In fact, you are all very kind-hearted, simple and kind-hearted, but it always makes people feel cold. I think it's better to put yourself in time when speaking, Don't treat yourself as a bystander, as if it's none of your business. Especially sometimes, before you say something, imagine yourself as the other party. Think about whether it's wrong to say that. Once you say something, you can't take it back. So think clearly before you say it. In addition, she has a problem with intonation. I don't know if you have this problem. When you speak, you should try to be calm at the beginning. Don't blame her. In the end, she always uses a rising tone and turns around, which makes people feel very disdainful. She may not pay attention to it, but the listener is uncomfortable

finally, in a wordy sentence, people with stiff attitude, use more polite words, please, thank you, sorry, courtesy is not strange, smile is important! Appropriate smile, appropriate small joke, is to let people think you are lovely, can be close to a start, learn to smile, don't disdain this, I taught my friend this for a long time, now she knows, the importance of smile!

5. I sincerely suggest that we should consider such a risk-free and Multiplication No franchise fee, no pressure Legal Not only the proct quality is high The price of the procts is also very cheap Sales and consumption are accumulated forever Procts are getting cheaper and cheaper Don't hurt yourself, don't hurt others Don't worry about contacts A business that grows forever, Nickname communication

6. It seems to point to the place where you want to dig a hole. There are carbon blue crystal diamonds, gold, red stone and iron on it. It's rich

8. Hello, I studied science and engineering before, and I also worked in human resources administration after graation, but I failed for various reasons. Now I've got another job and I'm happy. It can also be regarded as summing up experience in failure. In fact, human resource training is only professional knowledge, and even things with skills are limited. After all, a lot of experience is summed up in work. I've learned a lot from the work of human resources administration. I can share with you that ability is important in the workplace (generally, people who just came out of University highlight their ability), but inverse quotient and emotional quotient are more important. When you arrive at a new environment, you should first adapt to the environment, not only listen to the arrangement of the leaders, but also figure out how to get a foothold in the new environment, Because the environment is different, based on different conditions, it needs your EQ to help you, of course, a new environment is very likely to be excluded, it needs your inverse quotient to help you quickly adapt to the environment. Human resources administration should not only complete the boss's arrangement, but also make the environment harmonious. That's about your affinity. Human resources administration may be related to affinity, but it's not the whole work of human resources administration. No matter how much affinity you affect others' interests, it won't be accepted by others. Therefore, we must be careful in our manners and wording. We must be more tactful. It's about cultivating your Eq. At the beginning, when you have no way to start, just smile more. When others talk to you, you also listen with a smile. Later, when you have a smile, you need to add more words. Remember that you must say the closing sentence of the last sentence when chatting with others. This will prevent others from saying something to you. Sometimes you remember it in your heart, but you can't express it. This will easily cause communication barriers. Affinity has something to do with personality, but I believe affinity can also be cultivated. As long as you like this direction, you can work hard in this direction. Nothing is impossible
you may not have much work experience when applying for personnel work now. Give yourself a time to continue to look for personnel work. You are not afraid to sit up from the bottom of personnel. If you want to develop in this field, you need to have the spirit of lying on your back and tasting your courage. If you still can't find a job in personnel for a period of time, just transfer to administration. Take your time. There are many successful examples of transferring from administration to personnel. Usually look at "Du Lala promotion" to encourage yourself, come on!
