4.2 Adequacy analysis of conditional configurations
Adequacy analysis uses a truth table algorithm to identify whether a configuration is a sufficient configuration of a result, and when the agreement between a particular configuration and the result is greater than or equal to 0.75, the configuration can be considered as the adequacy configuration of the result [12]. Referring to the widely accepted practice in previous studies [15], the original consistency threshold is set at 0.8 in this paper. In addition to the consistency threshold, the number of cases covered by a particular configuration is also a screening criterion for a particular configuration to enter the Boolean minimization process. The frequency threshold of small and medium-sized samples (10ཞ100 cases) should not be less than 1, and the frequency threshold of large samples can be appropriately increased. In this paper, the case frequency threshold is set to 2, and the complex, concise and intermediate solutions of the model are calculated by fsQCA 3.0 software, and Table 5 shows the conditional configuration analysis results for farmers to effectively adopt the technology of reducing chemical fertilizer application and increasing efficiency. According to the theory of Richwood and Larkin(2017), this paper mainly refers to the intermediate solution to explain the processing results of QCA and combines the degenerate solution and the intermediate solution to identify the core conditions and edge conditions of the configuration. If an antecedent condition occurs in both the concise solution and the intermediate solution, it is the core condition; If the antecedent condition occurs only in the intermediate solution, it is an edge condition. A solid circle (●) indicates that a condition exists, a crossed circle (⊗) indicates a condition is missing, a large circle indicates a core condition, and a small circle indicates an edge condition. There were three antecedent configurations with explanatory power to improve the behavioral effect of farmers, and their overall consistency was 0.868, which was higher than the theoretical threshold of 0.8, and the consistency of single antecedent configuration was 0.916, 0.888, and 0.811, respectively, which were also higher than 0.8, indicating that these three antecedent configurations were sufficient conditions for improving the behavioral effect. The overall coverage rate was 0.537, indicating that these three configurations could explain the real-world cases to a certain extent. In general, these three different configurations can better improve the behavior effect of farmers' adoption of technology, and they are equivalent, that is, "different paths to the same end".
Configuration 1 is summarized as the endowment willing-dominated model, which indicates that even if the farmers' psychological cognitive level is low, and the constraints of the external context such as regulatory and encouraging government measures and organizational models are weak, the willingness to actively participate can improve the adoption of farmers. Improved performance of green agricultural technologies. Among them, technology transformation, endowment willingness, and encouraging government measures are the core conditions, and the organizational model and regulation are the core conditions type of government measures are marginal conditions. This configuration can be expressed as: when the effect of technology sinking application transformation has not appeared, and a series of encouragement and regulatory measures such as government supervision cannot play an effective role, the local area. When agricultural cooperatives and leading enterprises fail to provide substantive technical training services, and farmers do not have a general understanding of new green agricultural technologies, if farmers. The willingness to adopt endowment plays a leading role, and the willingness and behavior can also maintain a high level of consistency. Through in-depth interviews, it is learned that the farmers who meet this configuration have obvious common characteristics: they have actively participated in the new green agricultural technology training organization meeting for many times and adopted green agriculture. The quality of the agricultural products produced has also been significantly improved, and above-average profits can be realized, which has become a strong driving force for the transformation of farmers' endowment intentions into sustainable behaviors and has produced good performance improvement after the adoption of technology. Furthermore, it is found that different agricultural business entities are based on examining the cost of technology adoption, the profit margin of technology adoption, the risk of technology adoption, and the ability to apply technology, the business endowment of the subject is judged. Among them, the demand for new green agricultural technology for small-scale subsistence farmers and small-scale part-time farmers is mainly reflected in the substitution of labor factors through technology, reducing the labor burden, reducing the negative impact of the transfer of high-quality labor to non-agricultural fields, and stabilizing the output level of production factors such as labor and land. Its business scale is generally small, so the growth of its technology update income is very limited, and it is unwilling to bear the high cost of technology adoption, showing the characteristics of strong technology adoption risk aversion; family farms or large planters are guided by market demand and pursue the goal of high-yield, high-quality, and high-efficiency agricultural production The expected benefits brought by new green agricultural technologies are more attractive to them, and the ability of this type of farmers to bear the adoption risk and cost is higher than that of small-scale farmers.
Configuration 2 is summarized as an internal and external joint constraint model, which indicates that the improvement of farmers' performance requires external situational conditions such as regulatory government measures and market vitality, and at the same time, farmers' subjective cognition is internal. The foundation, endowment willingness, organizational model and encouragement government measures play a supporting role, and various internal and external factors interact with each other as antecedent conditions. Among them, the organizational model, regulatory government measures, and encouraging government measures are the core conditions, endowment willingness, and market vitality is an edge condition. This configuration shows that the establishment of individual behavior of farmers in the middle stage of technical training depends on the cognition of the technical information environment, and the initial decision of farmers to adopt new green agricultural technologies requires regulatory government measures Under the guidance of external compulsory system changes, the cognition formed is often more concrete, clear and stable, which is more conducive to the transformation of farmers' adoption behavior from passive acceptance behavior to active sustainable behavior. In the field visit and research, it was found that most farmers were aware of environmental problems such as the deterioration of the agricultural production environment and agricultural non-point source pollution, and generally had the awareness of green agricultural production and clean and circular production, but the degree of implementation of the behavior was still there. It is relatively low, showing the contradictory phenomenon of "high cognition and low behavior". If the government imposes mandatory regulatory measures to strengthen the supervision and punishment of violations of the treaty on the quality and safety of green agricultural products, farmers, as rational smallholders, will first consider the additional costs incurred, and when the marginal benefits of individuals are less than the marginal costs, farmers will take the initiative to adopt and Xi learn green agriculture driven by loss aversion Technology. Regulatory government measures can guide and regulate farmers' production behaviors, and promote the transformation of cognition into endogenous power, that is, the combined pressure of subjective psychological factors and external situations can guide farmers to effectively adopt green agricultural technologies.
Configuration 3 is summarized as an external context-led model, in which the effective adoption of green agricultural technologies by farmers mainly depends on the role of external contexts such as organizational models and regulatory government measures. The complementary role of endowment willingness and encouraging government measures. Among them, endowment willingness, organizational model and encouraging government measures are the core conditions, and technology transformation and regulation government measures are marginal conditions. This configuration reflects that the farmers who participated in the technical training at the beginning are not willing to increase their awareness of green agricultural technologies and their endowments. The supervision of environmental pollution and the quality and safety of agricultural products can enhance the restraining effect on farmers' non-standard behaviors, and agricultural cooperative organizations can effectively play an incentive and guiding role to make up for the shortcomings of farmers' scattered production behaviors. On the one hand, the traditional production mode of high input and high output makes farmers have a strong willingness to change, and in the early stage of farmers' transformation of fertilization behavior, the government clearly puts forward requirements and restrictions on the production process of agricultural products, which reduces the possibility of farmers' speculative behavior to a certain extent, and farmers have to do so under high-intensity supervision Change the traditional production mode and adopt clean and circular green agricultural production technology. On the other hand, the organizational model is to induce institutional changes, and the cooperative organization provides technical training services for members, unifies the production factors such as materials required for technology, and implements standardized management of the production process, unified purchase and sales of agricultural products and other socialized services, which can be realized by farmers under large-scale production "High quality, good price", long-term and stable economic income stimulates farmers to form strong behavioral motivation, and further improves the performance of farmers in adopting green agricultural technologies(Figure 3).
Comparing configuration 2 and configuration 3, it is found that there is a substitution relationship between technology transformation and organizational mode when regulatory government measures occur. Only one condition exists in the technology transformation and organization model to improve the behavior effect of farmers' adoption of technology. Summarizing the above three configurations, the effectiveness of psychological perception and external situation factors is different in the farmers at different stages of technical training, and the farmers in the early stage need more joint pressure from the external environment such as regulatory government measures and organizational models, and the farmers in the middle stage gradually form pairs. However, the guiding and normative role of regulatory government measures is still indispensable, and the willingness of farmers' endowment occupies a dominant position in the later stage, which can directly promote the effective adoption of farmers Green agricultural technology.
