Description

Technical Field

[0001] The present invention relates to an indicator index construction method and a system for evaluating the level of construction of a strong transportation country, and belongs to the field of evaluation of the level of development of a strong transportation country. Background Art

[0002] The evaluation index of a strong transportation nation is a comprehensive system that aims to comprehensively evaluate a country's development level and construction achievements in the field of transportation. These indicators usually cover multiple aspects to ensure the comprehensiveness and accuracy of the evaluation.

[0003] The existing technologies have many deficiencies in the calculation of evaluation indicators for a strong transportation nation, which are mainly reflected in the following aspects: Data complexity and correlation: The evaluation index system of a strong transportation nation covers multiple fields such as railways, highways, water transport, civil aviation, postal services and urban passenger transport. The index data calculation process in these fields is complex, and there is a certain correlation between the indicators. Existing technologies are difficult to effectively quantify and process these complex data relationships, which affects the accuracy and reliability of the calculation results.

[0004] Calculation time and human resource consumption: Due to the complexity and relevance of indicator data, existing technologies often require a long time and a large amount of human resources when calculating comprehensive indexes. This high-consumption measurement method is not only inefficient, but also costly and difficult to adapt to the rapidly changing needs of transportation development.

[0005] Missing international data: When making international comparisons, international data for some indicators are missing, which makes it difficult for existing technologies to comprehensively and accurately assess the level of development of major countries in the world in terms of transportation power. The problem of missing data makes it impossible to conduct effective extended measurements, affecting the integrity and international comparability of the evaluation indicator system.

[0006] Timeliness and dynamic updating: The evaluation indicators of a strong transportation nation need to be timely to reflect the latest transportation development status. However, existing technologies lag behind in data updating and calculation, making it difficult to achieve dynamic updating and real-time monitoring of indicator data, which limits the timeliness and foresight of the evaluation indicator system. Summary of the invention

[0007] In order to overcome the defects of the prior art, the present invention provides an indicator index construction method for evaluating the level of construction of a strong transportation nation. The technical solution of the present invention is: A method for constructing an indicator index for evaluating the level of building a strong transportation nation includes the following steps: (1) Constructing the primary evaluation dimensions and secondary evaluation indicators of the Transportation Power Index; (2) Determine the connotation, definition, calculation formula, statistical caliber and evaluation standards of the evaluation indicators for a strong transportation nation, obtain basic data, and revise the results according to the ranking scoring method if there are orders of magnitude differences in the original calculation results of the basic data; (3) Standardize the basic data of the indicators to obtain dimensionless data; (4) Modify weights through homogeneous classification, basic feature weighting and differentiation method; (5) Use the weighted analysis method to construct an index and synthesize the transportation power index; (6) Assess the progress of building a strong transportation nation based on the scale and growth rate of the Strong Transportation Nation Index.

[0008] The step (3) is specifically as follows: Step 3-1, missing data processing: For the values ​​that cannot be obtained, the data are supplemented by linear interpolation based on the data development trend; Step 3-2, data result correction: if there is an order of magnitude difference in the measurement results, the results will be corrected according to the ranking scoring method; Step 3-3, benchmark value setting: select a stable year as the benchmark year, and the average of the top five countries in that year as the benchmark value, that is, x; Step 3-4, standardization: standardize the three types of positive indicators, negative indicators, and interval indicators respectively. For positive indicators, the larger the indicator value, the higher the standardized score. The standardization formula is: , where x i is the current value of the indicator in the i-th year, and x is the evaluation benchmark value of the indicator; For reverse indicators, the smaller the indicator value, the higher the standardized score. First, the reverse indicator is processed inversely and then standardized according to the method of positive indicators; For the appropriateness index, a piecewise function is used for processing. The ideal state is within the target interval, and the deviation from the threshold is used to standardize the state beyond the target interval. The specific formula is as follows: , where [A,B] is the ideal threshold interval of the indicator.

[0009] The step (4) is specifically as follows: Step 4-1, equal weighting: assign equal weight a to each secondary transportation power evaluation indicator; Step 4-2, homogeneous classification: calculate the correlation coefficients between the evaluation indicators respectively, and merge the indicators with correlation coefficients above 0.95 into one indicator, and the weight after that is a / 2; Step 4-3: Ranking by importance and assigning weights: Under the first-level evaluation dimension, select industry management departments and authoritative experts to form a special team, and use the Delphi method to score and rank the first-level evaluation dimensions, that is, to make qualitative judgments on the weights of safety, convenience, efficiency, greenness and economy, and use the expert scoring method to obtain the weights of each evaluation dimension, and then set the weights of indicators under each evaluation dimension according to the number of indicators; Step 4-4, differentiated correction weights: Based on the principal component analysis method, the weights of various indicators under the same evaluation dimension are differentiated and corrected. The weights are corrected by measuring the cumulative contribution of the principal components of the evaluation indicators under each evaluation dimension, and the main influencing factors are analyzed, that is, representative indicators are selected, and the indicator weights are quantitatively adjusted based on this. The calculation method of the principal component contribution rate is as follows: ; Among them: p is the number of indicators, λi and λk are eigenvalues.

[0010] The step 3-2 is specifically as follows: First, determine the full score, that is, clarify the full score that the highest ranking can get, which is generally 4 points; second, calculate the basic score. The basic score obtained by the last ranking is 40% of the full score, that is, 1.6 points; The third is to calculate the difference ratio. The difference ratio is calculated by subtracting the last value c from the index value a of the evaluated unit, and then dividing it by the optimal value b minus the last value c, and the difference ratio is (ac) / (bc)=d; Fourth, calculate the middle score, which is the product of the difference ratio and the difference between the full score and the basic score, that is, the middle score is d*(4-1.6)=2.4d; fifth, calculate the total score, which is the sum of the basic score and the middle score, that is, the total score is 1.6+2.4d=e. In this way, the score of each ranker is calculated according to the ranking order and indicator value to narrow the differences between different objects.

[0014] The present invention will be further described below in conjunction with specific embodiments, and the advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are exemplary only and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements all fall within the scope of protection of the present invention.

[0015] See also Figure 1 The present invention relates to a method for constructing an indicator index for evaluating the level of building a strong transportation nation, comprising the following steps: (1) Constructing the primary evaluation dimensions and secondary evaluation indicators of the Transportation Power Index; (2) Determine the connotation, definition, calculation formula, statistical caliber and evaluation standards of the evaluation indicators for a strong transportation nation, obtain basic data, and revise the results according to the ranking scoring method if there are orders of magnitude differences in the original calculation results of the basic data; (3) Standardize the basic data of the indicators to obtain dimensionless data; (4) Modify weights through homogeneous classification, basic feature weighting and differentiation method; (5) Use the weighted analysis method to construct an index and synthesize the transportation power index; (6) Assess the progress of building a strong transportation nation based on the scale and growth rate of the Strong Transportation Nation Index.

[0016] Based on the settings in the above steps, the following advantages are achieved: Comprehensiveness: By constructing primary evaluation dimensions and secondary evaluation indicators, this method can comprehensively cover all aspects of building a strong transportation nation and ensure the comprehensiveness and accuracy of the evaluation results.

[0017] Scientificity: Determining the connotation definition, calculation formula, statistical caliber and evaluation standards of the evaluation indicators ensures the scientific nature of data acquisition and processing and improves the reliability of the evaluation results.

[0018] Standardization processing: Standardize the basic data of indicators to obtain dimensionless data, which solves the comparability problem of different indicator data and makes the evaluation results more fair and objective.

[0019] Weight correction: The weights are corrected by homogeneous classification, basic characteristic weighting and differentiation method, which ensures the rationality and scientificity of the weights of each evaluation indicator, reflecting the importance of each indicator in building a strong transportation country.

[0020] Weighted analysis method: The weighted analysis method is used to construct an index and synthesize the strong transportation nation index, so that the evaluation results can comprehensively reflect the overall level and progress of the construction of a strong transportation nation.

[0021] Dynamic assessment: Based on the scale and growth rate of the Strong Transportation Nation Index, the progress of building a strong transportation nation is assessed, so that the evaluation results can dynamically reflect the changes and development trends in the construction of a strong transportation nation.

[0022] Decision support: Provide continuous, reliable and scientific data support to industry management departments, help decision makers see the gap and shortcomings between my country and different countries from an international perspective, and provide important basis for decision making.

[0023] Cost-effectiveness: By optimizing the data processing and analysis process, the cost and time consumption of evaluation work are reduced, and the efficiency and benefits of evaluation work are improved.

[0024] Strong adaptability: This method can adapt to the traffic development characteristics of different countries and regions and has wide applicability and flexibility.

[0025] The step (1) is specifically as follows: with the goal of basically building a strong transportation nation by 2035, with safety, convenience, efficiency, greenness and economy as the basic value orientation, which are set as the first-level evaluation dimensions of the strong transportation nation index; under the five basic evaluation dimensions, combined with the specific tasks and goals of building a strong transportation nation, international comparative evaluation indicators of the strong transportation nation are selected according to representativeness, comparability, availability and timeliness, which are set as the second-level evaluation indicators of the strong transportation nation index.

[0026] The step (2) is specifically as follows: determining and measuring indicators, respectively determining the connotation definition, calculation formula, statistical caliber and evaluation standard (i.e., forward type, reverse type and interval type) of the evaluation indicators of a strong transportation country, respectively measuring the evaluation indicators of a strong transportation country, i.e. obtaining the basic data of the evaluation indicators of a strong transportation country, including the basic data of major countries in the world.

[0027] The step (3) is specifically as follows: Step 3-1, missing data processing: For the values ​​that cannot be obtained, the data are supplemented by linear interpolation based on the data development trend; Step 3-2, data result correction: If there is an order of magnitude difference in the measurement results, the results will be corrected according to the ranking scoring method; specifically: First, determine the full score, that is, clarify the full score that the highest ranking can get, which is generally 4 points; second, calculate the basic score. The basic score obtained by the last ranking is 40% of the full score, that is, 1.6 points; The third is to calculate the difference ratio. The difference ratio is calculated by subtracting the last value c from the index value a of the evaluated unit, and then dividing it by the optimal value b minus the last value c, and the difference ratio is (ac) / (bc)=d; Fourth, calculate the middle score, which is the product of the difference ratio and the difference between the full score and the basic score, that is, the middle score is d*(4-1.6)=2.4d; Fifth, calculate the total score, which is the sum of the basic score and the middle score, that is, the total score is 1.6+2.4d=e. In this way, the score of each ranker is calculated according to the ranking order and indicator value to narrow the differences between different objects; Step 3-3, benchmark value setting: select a relatively stable year as the benchmark year, and the average value of the top five countries in that year as the benchmark value, that is, x; Step 3-4, standardization: standardize the three types of positive indicators, negative indicators, and interval indicators. For positive indicators, the larger the indicator value, the higher the standardized score. The standardization formula is:

[0028] Among them, x i is the current year value of the indicator in the ith year, and x is the evaluation benchmark value of the indicator.

[0029] For reverse indicators, the smaller the indicator value, the higher the standardized score. The reverse indicators are first processed inversely and then standardized according to the method of positive indicators.

[0030] For the appropriateness index, a piecewise function is used for processing. The ideal state is within the target interval, and the deviation from the threshold is used to standardize the state beyond the target interval. The specific formula is as follows: , where [A,B] is the index xi The ideal threshold range.

[0031] The step (4) is specifically as follows: Step 4-1, equal weighting: assign equal weight a to each secondary transportation power evaluation indicator; Step 4-2, homogeneous classification: modify the weight through correlation analysis, calculate the correlation coefficient between the evaluation indicators respectively, and merge the indicators with correlation coefficients above 0.95 into one indicator, and the weight is a / 2; Step 4-3, rank by importance and assign weights: Under the first-level evaluation dimension, select industry management departments and authoritative experts to form a special team, use the Delphi method to score and rank the first-level evaluation dimension, that is, make a qualitative judgment on the weights of safety, convenience, efficiency, greenness and economy, and use the expert scoring method to obtain the weights of each evaluation dimension. Then, the weight of the indicators under each evaluation dimension is set according to the number of indicators. For example, the weight under the "convenience" evaluation dimension is b, and the number of convenience indicators is 3, then the weight of each evaluation indicator is b / 3, and the weights of all indicators (where the weights of the indicators in step 4-2 remain unchanged) are calculated by class inference one by one; Step 4-4, differentiated correction of weights; based on the principal component analysis method, differentiated correction is made to the weights of various indicators under the same evaluation dimension. The weights are corrected by measuring the cumulative contribution of the principal components of the evaluation indicators under each evaluation dimension, and the main influencing factors are analyzed, that is, more representative indicators are selected, and the indicator weights are quantitatively adjusted to avoid the strong influencing factors of some evaluation indicators leading to "magnification" of the gap between different countries in this field. Among them, if there is no obvious difference in the indicators under a certain evaluation dimension, it is considered that the indicators under this dimension are equally important and have equal weights, that is, the weight remains unchanged. For example, if there is no obvious change in the contribution of each indicator under the "convenience" evaluation dimension, the weight b / 3 remains unchanged; for indicators with large differences in various indicators under a certain evaluation dimension, that is, indicators with a cumulative contribution of the principal component greater than 80%, it is considered that the weight of the indicator is the product of the original weight and the cumulative contribution. For example, if the weight under the "green" evaluation dimension is c and the number of indicators is 3, then the weight of each evaluation indicator is c / 3. According to the principal component analysis method, the cumulative contribution of the i-th indicator is 85%, then the weight of the i-th indicator is 1.85*c / 3, and the weights of the other two indicators are equal, both 1.15*c / 6. And so on. The calculation method of the principal component contribution rate is as follows: Among them: p is the number of indicators, λi and λk are eigenvalues.

[0032] The step (5) is specifically as follows: the index is finally constructed by using a weighted analysis method, the indexed value obtained in step (3) is multiplied by the weight obtained in step (4), and the transportation power index is obtained by weighted synthesis.

[0033] The above step (6) is specifically as follows: based on the scale and growth rate of the Strong Transportation Nation Index, effectively track and evaluate the progress of my country's construction of a strong transportation nation, and through benchmarking analysis with major countries in the world, find out the advantages, potential areas and gaps in my country's construction of a strong transportation nation, further make up for shortcomings, strengthen weaknesses, consolidate the foundation, and promote advantages, so as to provide important support for the quantitative evaluation of the progress of China's construction of a strong transportation nation.
