2017，I joined the "China Truck Driver Research Research Group"，Looking back on the research process of five years，Perseverance research and immersive survey is the most valuable research experience，It is also the most important path to "seeing the truth" expected to Mr. Fei Xiaotong。

vertical research is a classic research method with a long history，It means to record the status and changes of the research objects in different times within a long period of time，To reveal the process、Heterogeneity and cause and effect。Classic vertical studies usually use quantitative methods，But since 2000，More and more research innovatively adopts qualitative technology collection and analysis vertical data。Truck driver research has also adopted the vertical qualitative method，It is used to explore the labor process of truck drivers and the cross -result results of related factors。

As far as our research institute,，The classification of the vertical and qualitative research and the division of quantitative researchers tend to be consistent，can be divided into tracking research and trend research。Tracking Studies are repeated observations of the same book，Many truck drivers and cards have accepted our interview many times during the study period。Trend Study emphasizes different samples in the same overall period for different samples for testing，Our research also takes "transmission sample" as a sample pool，Choose different research objects in the same pool every year for participation and in -depth interviews。

When collecting vertical data，We consciously take into account its continuity bet365 best casino games and liquidity。Take my research as an example，Regardless of tracking research or trend research，My interview outline consists of fixed problems and changes based on theoretical attention: fixed issues include the population sociology characteristics of the respondent、Labor process、Social communication、Social communication、Gender concept、New media adaptation and future outlook，The problem of changes follows different research themes to perform specific extension: Carthade studies focuses on the gender labor division of the truck driver and wife，Female truck driver research focuses on professional gender isolation，Volunteer research takes the interaction between career and volunteer motivation as the focus，Cross -border transportation research will focus on the comparison of cross -border transportation and domestic transportation。

The benefits of vertical research are obvious。The most prominent is the continuous "emerge" of the research theme closely connected to the field on the field。The first way of "emerge" is the "emergence" of cross -analysis factors，It contains dual dimensions: one heavy dimension is a clear cross problem at the experience level，For example, the cross -topic of labor and gender begins with the confusion of the "husband and wife car" when studying the labor process，The cross -study of labor practice and volunteer services is also derived from the underlying social status perception that the truck driver repeatedly emphasized。Another heavy dimension is the possibility of constantly deepening interpretation at the theoretical level。Theoretical interpretation of the laborer role of Kajie，From the original "production helper and living housewife"，to "The indispensable worker of the road freight industry"，Then explain the tension Bet365 lotto review between the objective labor character "card" and the subjective gender character "嫂" through the change of gender concept，Deeply feels the theoretical progress space brought by the Institute of Passing。

The second way of "emerge" is reflected in the new subject brought by the life history of the research object。The research theme of volunteer service is to become a truck driver friend brought to me for a truck driver who has become anti -epidemic transportation volunteers，Research on cross -border transportation has started from a few years ago in the interview with Horgos Port，Until the recent transportation from domestic transportation to Laos、Thai and Myanmar truck drivers are more and more friends are increasing，This theme is naturally mentioned on the research agenda。This "emergence" is not only a single choice for researchers，It also often has the reflection of research objects，Fully shows their distinctive emotional color。

In addition to the continuous "emergence"，vertical research also increases the possibility of comparison。The first is the comparison of the history of the individual life of the subject。In five years of research，We observe the truck driver around at a close range、Supply、Employment Nature、Transport distance and industry，Accompanying Card from the car to staying in the stay、From staying to the car again，I also witnessed the growth of many Kawa。The vertical contrast of each micro life history constitutes a stroke of the history of the highway freight in my country。Followed by the comparison of research data。Although there are clear themes every year research，But thanks to the persistence of vertical research，We compared many themes。For example, when studying cards and female truck drivers，I can read the interview information of the male truck driver Bet365 lotto review and other practitioners for comparison，Then summarize the more complete industry gender concept。Finally is a comparison of the macro institutional environment and the market environment。Five -year vertical research gives us the opportunity to experience changes in various macro policies and market demand with truck drivers，For example, the implementation of the "charging of the axis" policy，"Fatigue Driving" law enforcement transformation，Upgrade of environmental protection policy，Updated iteration of models，The rise and monopoly of the online freight platform，zero burden、Large pieces、Express、Express、Transformation of Cold Chain and Lvtong Market，These comparisons constitute the essential industry background of studying truck drivers，It also provides us with a macro option for causal relationships for the micro individual choice of truck drivers。

　　Between "Real" and "Knowing": the necessity of immersion field survey

If the focus of vertical research is to repeatedly explore the research objects at different times in the long period of time，So the immersive field survey emphasizes the use of all possible means to collect information and analyze in depth，Makes the physical and mental body and mind of the researchers always immersed in the field field bet365 Play online games between "real" and "knowledge"。

On the one hand，Researchers need to be immersed in concentrated field surveys。Field surveys under concentrated offline every year are the main contents of truck driver research，But the limited nature of time and place，We need to extend the rich meaning of unlimited extension of limited space and space。So，Investment interviews with all your heart、In addition to the discussion and observation，We always work hard to collect all possible information: the contact process with the contact person and the respondent、Determination bet365 Play online games of various field investigations、The natural environment and local customs of the field location、Silence and tears during the interview in the interview、Truth revealed the true feelings of the visitor after turning off the recording pen、Interrupted issues and rejected interviews，Especially abnormal cases and knowledge that needs the silent meeting，These all need to be understood and recorded in the theoretical sense。

What needs to be pointed out is，Participating in observation is an indispensable component of immersive field surveys，It provides "Live A sense" that is difficult to reach and the discussion in the interview and discussion。When studying female truck drivers in 2019，I used to go to a courier company to observe the morning meeting of the driver group。When I am a woman, I entered the office、When you see that in the narrow space or almost all the male truck drivers, the male truck driver，That kind of professional gender isolation brings to the oppression of a minority of professional gender, coming to the face。In the same year, I also followed as a part -time loader and followed a city -matching sister sports car，We must quickly unload the goods for every unloading point，Then rush to the next unloading point without stopping，The urgency of the "rushing number" made me immediately realize the difference between different freight labor division of labor。2023，We will follow a medium and long -distance Kago delivery，When we start on the road at 2 am at 2 am in the silence,，It is found that the highway at night is the world of trucks: different types of trucks shoulder shoulders、Extraordinary，and the trucks that are neatly stopped along the way，Carrying a truck driver's resting for the extreme compression，It also shows the desolation of individual workers under the continuous prosperity of Sichuan。Bet365 lotto review This kind of "live sense" transformed the language of interviews and discussions into real sounds、picture and situation，Is the irreplaceable field of field。

On the other hand，Researchers need to be immersed in daily fields outside the concentrated field survey。For me，The daily fields include three opportunity composite parts。One is to carefully sort out the interview information，Reappear the scene of "Real"，and repeatedly ponder its true meaning、By theory involved the theory of "knowledge"。I am used to combining the sorting information with the first code to one，Many theoretical architecture and demonstration logic comes from this hard and joyful process of knowledge。The second is to accumulate related "New Era Data"。Except academic theory，I also followed 47 and the road freight industry、Logistics industry、WeChat public account related to the car industry and truck driver，also downloaded several large online freight platforms and APP。I will pay attention to information published by these platforms every day，Articles related to research、Pictures and Video Separation for Save。WeChat public account related to the car industry and truck driver，allow me to maintain the field of field "on the scene" as much as possible。The third is to collect multiple data that is defined by scholars as "content of workers"，For example, a truck driver、WeChat friends circle of Card and related practitioners、Douyin、Quick Hand、Card Friends Organization APP Posting, etc.。This part shows me the diverse and real work and life of the research object，It is necessary to supplement the limited interview information。

The study of the truck driver tells us，vertical research can promote the expansion of research theme and theoretical comparison，An immersive field survey will set up a bridge for experience and theoretical interaction bet365 Play online games between "real" and "knowledge"，The organic combination of the two can enhance our perception and insight in social phenomena，More effectively excavating the unique "constant" and "social heritage" of Chinese society。
