Empirical Study on the Degree of Coupling Coordination Between Ice-snow Tourism and Cultural Industry Integration ——Take Harbin as An Example

Harbin is the capital of Heilongjiang Province in China, the ice-snow tourism industry develops rapidly. How to integrate with the cultural industry and cultivate a new growth point of Harbin is a hot research area. Harbin culture and tourism industry has a good foundation, the development of industry integration accelerates and infrastructure is increasingly perfect. However, it also faces some practical problems, such as the lack of the depth of industrial resources exploitation and utilization efficiency, the low integration degree of ice-snow tourism and cultural industry chain, and the lack of cultural products of highend music and painting leisure tourism. Build a coupling and coordination model and have a empirical analysis of the degree of coupling coordination between Harbin's ice-snow tourism and cultural industry integration, the conclusion is that the coupling coordination is low and the development of cultural industry lags behind.


Introduction
Harbin is the capital of Heilongjiang Province, with many geographical and cultural advantages, which also determine that Harbin Ice-snow tourism has a solid foundation and unique conditions. From the data of icesnow tourism in recent years, we can see that Harbin's tourism industry is developing very rapidly, and has a well popularity and reputation. Harbin has a rich variety of tourism products, including Ice-snow World, ice lantern exhibition, snow sculpture exhibition, Ice-snow paradise, skating and skiing, curling and other entertainment ways and places. It is well-known at home and abroad, attracting countless tourists to watch and experience, making Harbin a famous tourism city with ice -snow projects as the main body in China. It is precisely because of the advantages of ice and snow that we can develop ice-snow tourism industry, so as to drive the development of other industries, inject vitality into the economic development of Harbin and make the economy develop continuously. Ice-snow culture has a great impact on Harbin's urban construction, If we want to develop Harbin Ice -snow tourism industry well, we should pay attention to its connotation development, especially the development of ice-snow industry culture connotation. To show and promote Harbin Ice-snow tourism industry from the perspective of culture can get twice the result with half the effort. Integrating the black land culture into the ice-snow tourism project can more effectively attract domestic and foreign tourists and improve the influence of Harbin Ice-snow tourism. Adhering to the connotative development road can integrate the ice-snow tourism industry into the multi culture, integrate the ice-snow tourism resources in Harbin, make it play a greater advantage, attract more tourists, obtain higher economic benefits, drive the development of other industries, and constantly promote the better and faster development of ice-snow tourism industry in Harbin.

Index selection and its weight
According to the principles of representativeness, systematicness, scientificity, and availability of indicators, 8 indicators of Harbin ice-snow tourism industry and cultural industry are selected, with a total of 16 indicators. Using U 1 represents the overall development index of ice-snow tourism industry, U 2 represents the general index of cultural industry development. The specific index, unit and weight are shown in Table 1 should be typed in 9-point Times.

Data sources and processing
Data sources. This topic selects the relevant data of Harbin from 2011 to 2019, mainly from the statistical yearbooks of Harbin, Heilongjiang, China, China Tourism and Chinese cultural relics, as well as the public websites of Harbin Bureau of statistics, Heilongjiang Provincial Bureau of statistics and relevant governments. Data processing. According to the above selected indicators, according to the annual data order, the initial data matrix needs to be constructed, as follows. (1) In the above publicity, i represents the year, j represents the number of indicators, Xij represents the jth index value in the i-th year. This topic needs to establish the coupling coordination degree model of icesnow tourism and cultural industry. The selected indicators include positive and negative indicators. The extreme value method is used to deal with the dual indicators differently, and 0.01 is added to the index data to ensure that the calculated data is meaningful. Here Xij expressed as j i X ' ,This standard value after dimensionless is between 0-1, and the value range is directly proportional to the contribution. If it is 1, it reaches the maximum value.

Evaluation criteria and synchronization
Evaluation criteria. In order to calculate the coupling coordination degree of Harbin ice-snow tourism and cultural industry, the evaluation standard of coupling coordination degree should be made clear. Based on the method of uniform distribution function and the successful experience of previous studies, combined with the development characteristics and regionalism of ice-snow tourism and cultural industry in Harbin, the coupling coordination dispatching interval is divided into five levels. The specific levels and standards are shown in Table 2  Coupling coordination degree and synchronization. This paper not only calculates the degree of coupling coordination to the degree of synergy and closeness of the integration of ice-snow tourism and cultural industry in Harbin, but also further illustrates the synchronization of the integration of the two industries. P is used to represent the synchronization of the integration of the two industries, and the calculation formula is as follows.
That is, the synchronism is equal to the comprehensive development index of ice -snow tourism industry U 1 divided by the comprehensive development index of cultural industry U 2 , that is to say, the ratio of the two is used to explain the synchronization of the two. When P<1, it means that the development of ice-snow tourism industry lags behind; when P=1, it means that the two develop simultaneously; when P>1, It means that the development of cultural industry lags behind.

Evaluation criteria and synchronization
Using the coupling coordination degree model, according to the above calculation formula, the development index of Harbin ice-snow tourism industry(U 1 ), Cultural industry development index (U 2 ), The comprehensive evaluation index of the two industries(T), Coupling degree of the two industries(C), Coupling coordination degree of two industries(D), Synchronization of the two industries(P) are calculated. The corresponding partition interval and coordination degree are shown in Table 3.

Evaluation criteria and synchronization
According to the above calculation results, a dynamic fitting figure is drawn of the coupling degree of Harbinice-snow tourism and cultural industry(C) Coupling coordination dispatching(D) and synchronization(P), as shown in Figure 1.
Coordination degree analysis. It can be seen from Figure 1 that the coupling degree between ice-snow tourism and cultural industry in Harbin is always at a high level. The coupling degree increased from 0.789 in 2011 to 0.955 in 2019. Except that the coupling degree in 2011, 2012 and 2018 was lower than 0.9, the coupling degree in other years was higher than 0.9. It can be seen from the data that the coupling degree between Harbin ice-snow tourism and cultural industry presents three obvious stages: in the first stage, from 2011 to 2014, the coupling coordination degree increases year by year, from 0.789 in 2011 to 0.999 in 2014, and the coordination degree develops from moderate maladjustment to grudging coordination; in the second stage, from 2014 to 2018, the coupling coordination degree decreases year by year, from 0.789 in 2014 to 0.999 in 2014.In the third stage, in 2018-2019, the coupling coordination degree will rise to 0.955, and the coordination degree will return from mild maladjustment to grudging coordination.
It can be concluded that the coupling development of Harbin ice-snow tourism and cultural industry integration is a integration process which from maladjustment to coordination, then from coordination to maladjustment, and finally back to coordination. From 2011 to 2013, Harbin ice-snow tourism and cultural industry have little influence on each other and are independent of each other, which belongs to the early stage of integrated development. In 2014, the two industries grew rapidly, and the coupling coordination degree was greatly improved. Even if the coupling coordination degree decreased in 2015, it was still grudgingly coordinated. In 2016-2018, the ice-snow tourism industry developed rapidly, but the development of cultural industry lagged behind, leading to the E3S Web of Conferences 292, 03029 (2021) NETID 2021 https://doi.org/10.1051/e3sconf/202129203029 maladjustment of coupling coordination degree. In 2019, the degree of coupling and coordination between the two industries in Harbin increases significantly, and the icesnow tourism industry and cultural industry both increase significantly. Synchronization analysis. It can be seen from Figure  1 that the synchronous change range between ice-snow tourism and cultural industry in Harbin is large. From the perspective of change process, the synchronization can also be divided into three stages: the first stage, from 2011 to 2014, the initial level of cultural industry in Harbin is relatively high, although the development of ice -snow tourism industry is relatively backward, but the development is relatively strong, catching up with the development of cultural industry in 2014.In the second stage, from 2015 to 2016, the ice-snow tourism industry is relatively lagging behind, and the two industries have declined to varying degrees, but the decline of ice-snow tourism industry is more obvious. In the third stage, from 2017 to 2019, the cultural production appeared recession, and the ice-snow tourism industry developed strongly. In 2019, the recession of cultural industry has eased, but the development momentum is not as good as the ice-snow tourism industry.

Low degree of coupling coordination
According to the above analysis, from 2011 to 2019, the overall coupling coordination degree of Harbin ice-snow tourism and cultural industry integration development is low. Except for 2014, 2015 and 2019, which are grudgingly coordinated, other years show maladjustment. The specific manifestation is that the coordination and driving effect between ice-snow tourism and culture industry is weak, for example, from 2011 to 2013, Harbin's cultural industry developed rapidly, but it did not promote the rapid development of ice-snow tourism industry. From 2016 to 2018, the growth of ice-snow tourism industry was stable, but the cultural industry did not maintain synchronous growth, and the integration of the two industries was once again maladjusted. Therefore, in order to improve the coupling coordination degree of Harbin ice-snow tourism and cultural industry integration development, we must first strengthen the coordination and driving role between the two industries.

The development of cultural industry lags behind
According to the synchronous analysis of the coupling coordination degree of Harbin ice-snow tourism and cultural industry integration development in Figure 1, since 2014, the development of Harbin cultural industry can't keep up with the development of ice-snow tourism industry, especially in 2016-2019, the development of cultural industry is slow, even declining, seriously lagging behind the rapid development of ice-snow tourism industry ,the main reason may be as follows ,First, there are few fiscal and tax incentive policies, even if there are incentive measures, the effect may not be obvious; second, the driving effect of icesnow tourism on the cultural industry is not obvious; third, the problem of the development of the cultural industry itself. Therefore, in order to promote the rapid development of Harbin's cultural industry, and make it integrate with the ice-snow tourism industry, promote each other, and develop together, we must increase the financial and tax incentive policy support, and actively play the leading role of the ice-snow tourism industry. At the same time, the cultural industry should also explore its own problems and improve its healthy and rapid development.
