2.1 The impact of the grassroots autonomous organizations embedding level on the farmer homestead exit behavior
Embeddedness theory is one of the core theories in the analytical framework of new economic sociology (Wang and Lu,2021), which was first proposed by Polanyi in 1944. The central idea is that individual economic behavior is closely linked to social relations, always embedded in non-economic factors such as customs (Granovetter M S,1984). Granovetter proposed the concept of "weak embeddedness". According to the new economic sociology, people's economic behavior is not only the pursuit of personal benefit maximization, but embedded in the social structure and affected by various social relations (Zhang et al,2020). Zukin and Dimaggio extended the connotation of embeddedness theory and divided embedding into political embedding, cultural embedding, cognitive embedding and structural embedding. At present, Chinese scholars' measurement index system division of embeddedness mostly follows this (Wang and Lu,2021). Embeddedness theory was initially applied to the analysis of business activities in China (Liang et al,2005), and was subsequently further used to analyze the interaction between economic entities. In combination with the practice of contemporary Chinese social transformation, many scholars have tried to establish an analytical framework of embedded governance in line with China's social reality (Jiang,2021; Yu et al,2021), and proposed that the realization of the expected goals of grassroots governments can be influenced by three embedding methods: system embedding, organizational embedding and interest embedding. Based on this, this paper defines the grass-roots autonomous organization as the grass-roots village committee and the villagers' groups. Combined with the actual research situation and the existing embedding index division system, the three factors obtained from the factor analysis are named as institutional embedding, organizational embedding and emotional embedding. Among them, the institutional embedding of grass-roots autonomous organizations refers to the standardization and legitimacy of grass-roots autonomous organizations in the process of promoting farmers to exit the homestead, as well as the guarantee of farmers' right to know (Shi et al., 2022; Tang et al., 2020; Zhang et al., 2021). This paper adopts the structure, politics and other indicators to express. The organizational embedding of grassroots autonomous organizations means that in the process of promoting homestead withdrawal, grassroots autonomous organizations fully consider the reasonable demands of farmers, protect the legitimate interests of farmers, and respect the will of farmers (Shi et al., 2022; Tang et al., 2020; Zhang et al., 2021). This paper uses benefit and cognitive indicators to express. The emotional embedding of grassroots autonomous organizations refers to the respect and protection of farmers' traditional culture, behavioral cognition and rural feelings when implementing homestead withdrawal policies (Shi et al., 2022; Tang et al., 2020; Zhang et al., 2021).This paper adopts emotional and cultural indicators to express.
Grass-roots autonomous organizations are the intermediary of transmitting policy information and ensuring people's livelihood between the grass-roots government and the farmers (Liu and Li, 2017). It is not only the propagandist of the government homestead withdrawal policy, but also the implementer of the farmers' homestead withdrawal policy. The embedding of grassroots autonomous organization can make it better realize its function of transmitting information from above and uploading information from below (Yu et al,2021). Village collective organizations are embedded in the village acquaintance society to conduct homestead management, and their behaviors are affected by the rural governance system and tasks (Liu and He,2018). The function of village collective organization plays a direct role in the decision of homestead withdrawal of farmers, and then affect the farmers whether to homestead exit (Sun et al,2020). Generally speaking, the leaders of grassroots autonomous organizations are farmers themselves. To improve the embedded level of grassroots autonomous organizations can analyze and deal with various problems in the process of mobilizing farmer homestead withdrawal from the perspective of farmers, and it also conducive to dispel the stereotype of farmers that grassroots autonomous organizations are only agents of the government and developers, eliminate the potential friction between grass-roots autonomous organizations and farmers, thus, farmers’ homestead withdrawal decisions will be affected(Zhou et al., 2018). Different embedded level of grassroots autonomous organizations have different effects on farmers’ homestead withdrawal.
When the grass-roots autonomous organizations have a high embedding level in terms of system and interests, they can meet the requirements of farmers for the right to know the withdrawal policy and the right to participate in the withdrawal compensation standard formulation, thus to safeguard farmers’ legitimate interests in the process of homestead withdrawal from the multi-interest game, and to improve the prestige of grass-roots autonomous organizations, furthermore, farmers are more likely to accept the homestead withdrawal mobilization activities of grassroots autonomous organizations. When the grass-roots autonomous organizations have a high embedding level in terms of culture and emotion, they can maximize meet the psychological and emotional demands of farmers, so that farmers reluctant to leave the countryside and reluctant to homestead withdraw. In conclusion, the embedding of grassroots autonomous organizations has an impact on the farmers' homestead withdrawal behavior. The stronger the embedding level of grassroots autonomous organizations in terms of system and interests, the more likely farmers are to exit homestead.The stronger the embedding level of grassroots autonomous organizations in terms of emotion, the less likely farmers are to exit homestead. Based on the above analysis, this paper puts forward the research hypothesis H1.
H1: The system embedding level of grass-roots autonomous organization and the interests embedding level of grass-roots autonomous organization have a significant positive impact on the farmer homestead withdrawal behavior. The emotion embedding level of grass-roots autonomous organizations has a significant negative impact on the farmer homestead withdrawal behavior. The overall impact of the embedding level of grassroots autonomous organizations on the farmer homestead withdrawal behavior is uncertain, which needs to be further tested empirically.
2.2 The impact of the non-agriculture employment on the farmer homestead exit behavior
Non-farm employment is a rational decision of farmers to maximize the household total welfare effect, and it is an important driving force to promote the homestead resources circulation. The farmer income level has a significant effect on the farmer's homestead withdrawal behavior (Sun et al,2020; Yan et al,2021; Xu and Xing,2021). At present, the farmers’ income structure shows a non-agricultural orientation, and the proportion of non-agricultural income in the total income is steadily increased (Cheng et al., 2021; Wang et al., 2021). It can be seen that the level of farmers’ non-agricultural employment has an important impact on their homestead withdrawal behavior. Therefore, this paper firstly chooses non-agricultural employment level index to study household non-agricultural employment. The difference of non-agricultural employment attribute will lead to the different direction and degree of non-agricultural employment level, while the non-farm employment distance can measure the stability of part-time employment and non-farm employment of farmers(Huang et al., 2022). Therefore, this paper further chooses the non-farm employment distance index to study the impact of non-farm employment on farmers' homestead exit behavior.
The impact of the non-agriculture employment level on farmers' homestead exit behavior. Learn from relevant research results (Zhou et al,2017; Xiang and Le,2021; Liu et al,2021; Xu et al,2022; Chang et al,2021; Liu and Zhang,2018). This paper selects the farmer household non-agricultural employment rate to measure the farmer household non-agricultural employment level (Chang et al,2021; Liu and Zhang,2018). Homestead withdrawal is a family choice behavior, which requires a unified opinion among family members on whether to withdraw (Sun et al,2020). When the household non-farm employment rate is low, more family members are engaged in agricultural production, and the household income is relatively low, so the ability to deal with potential risks after exit is lower, and the willingness to exit the homestead is lower. When the household non-farm employment rate is high, the household income is relatively higher, the ability to deal with potential risks is stronger, and the family members have higher requirements for convenient and comfortable living environment, which is conducive to the withdrawal of household homestead. Based on the above analysis, this paper puts forward the research hypothesis H2.
H2: The non-farm employment level has a positive effect on the farmer homestead withdrawal behavior.
The impact of the non-agriculture employment distance on the farmer homestead exit behavior. The part-time employment conditions in different employment places are different, which will lead to different support and limiting factors for the career development of rural labor force, and then affect farmers' choice of rural homestead withdrawal (Xu et al,2022). Referring to the existing literature, the distance judgment standard of non-agricultural employment is within and outside the county (Xu et al,2022). In this paper, the non-agricultural employment distance of rural household migrant laborers is divided into three types: near distance (in the local county), a little long distance (within the province) and remote distance non-farm employment (outside the province). For near distance non-agricultural employment farmers, their social networks such as clan blood and human relations serve as a link to drive farmers to help each other and disperse the non-agricultural employment risks they faced, seeking more opportunities for their non-agricultural employment (Zhang et al,2022), and taking more measures to deal with potential risks, therefore, farmers are more likely to exit homestead (Wang and Zhao,2021). For a little long distance non-agricultural employment farmers, their social networks and professional skills are weaker, material base is poorer, job and livelihood stability are less stable, and they face more potential risks, therefore, rural homestead as their final foothold and reserve assets, they choose to withdraw from the probability of homestead is small (Zhang and Xia,2021). For a remote distance non-agricultural employment farmers, long-term employment experience maintains a stable employment relationship, with relatively higher professional skills, higher career salary and higher non-farm employment income, the accumulated material capital makes them pay more attention to the time and energy cost of dealing with the withdrawal of homestead, and do not pay much attention to the reserve assets value of the homestead, and their connection with the countryside is relatively low, the emotional connection is shallow (Sun et al,2020). Therefore, farmers are more likely to exit homestead. Based on the above analysis, there may be a "U" -shaped trend between farmers' non-farm employment distance and their homestead withdrawal decision behavior when other conditions are unchanged. So, this paper puts forward the research hypothesis H3.
H3: The non-farm employment distance has a U-shaped impact on the farmer homestead exit behavior.
2.3 The moderating effect analysis of non-farm employment on the embedded level of grass-roots autonomous organizations and the farmer homestead withdrawal behavior.
According to the above analysis, we shows that the embedding level of grass-roots autonomous organizations has a significant impact on the farmer homestead exit behavior. In the Chinese homestead withdrawal pilot practice, due to the limited amount of withdrawal compensation, farmers need to pay certain extra costs in the process of homestead withdrawal(such as the decoration of new housing, the purchase of furniture, etc., which requires farmers to consider their payment capacity (Wang et al., 2021). With the improvement of urban economic development level and the household registration system reform, farmers will consider more expected returns and risk expectations when making decisions on whether to exit homestead (Su et al,2020).. Farmers with different degree of occupational structure differentiation and non-farm employment stability have different expected returns and ability to cope with risks, trust radius and trust level also differ (Liu et al,2020), so that they have different acceptance degrees of the credibility and authority of grassroots autonomous organizations.
In terms of non-farm employment levels, when the farmer’s non-farm employment level is low, the relationship between the farmer and the countryside is relatively close. at this time, the farmer’s income level is relatively low and the trust radius is small, there is a high relationship and closeness between grassroots autonomous organizations and the low non-agricultural employment level farmer, the farmer have a strong trust and dependence on the grass-roots autonomous organizations. therefore, when considering whether to withdraw from homestead, they will be affected by grassroots autonomous organizations. When the farmer’s non-farm employment level is high, the farmer’s income level is high and the trust radius is expanded, the farmers have low trust in the grassroots government. Therefore, the authority of grassroots autonomous organizations for farmers with high non-agricultural employment rate declined, whether the homestead exits or not more reflects the independent decision of the farmers. In terms of non-farm employment distance, the longer the non-farm employment distance, the weaker the social network between the farmer and rural areas, and the smaller the dependence and trust of the farmer on grassroots autonomous organizations. Therefore, grassroots autonomous organizations have less impact on farmer's decision to exit homestead. Based on the above analysis, this paper puts forward the research hypothesis H4.
H4: Non-agricultural employment plays a moderating role in the embedded level of grass-roots autonomous organizations and the farmer homestead withdrawal behavior. With the increase of the farmer non-farm employment level, the effect of grassroots autonomous organization embedded level on the farmer homestead withdrawal behavior will be weakened. With the longer of the farmer non-farm employment distance, the effect of grassroots autonomous organization embedded level on the farmer homestead withdrawal behavior will be weakened.
