The history of technology diffusion
The interviews and questionnaires revealed that the acquisition and diffusion of musical instrument manufacturing technology in Xuchang Village underwent a complex process. Before the 1980s, the industry in Xuchang Village was mainly based on wood processing and did not involve musical instrument manufacturing. Musical instrument factories in Shanghai only had business contact with neighboring villagers for wood processing, with no exchange or diffusion of musical instrument technology. However, in the mid-1980s, some resourceful villagers met many outstanding technicians from Shanghai’s No. 1 Folk Musical Instrument Factory and established contacts during that period, which laid the foundation for the spread of technology (Fig. 3). Based on when different actors mastered folk musical instrument manufacturing technology, we divided the technology diffusion process into four periods: contact and learning, imitation and derivation, scale diffusion, and radiation diffusion (Table 3).

Mechanism interpretation
|
Under the effect of cognitive proximity, local factories could quickly develop a group of followers and engage in folk musical instrument manufacturing.
|
Influenced by traditional Chinese social culture, folk musical instrument manufacturing technology was preferentially disseminated within the family (i.e., “own people”).
|
Economic and information development, the musical instrument industry was revived and began to change production and sales methods.
|
Government, media, market, and other factors contributed to the development and prosperity of the folk music industry.

Based on the history of technology diffusion, we can see that there were at least six actors of technology diffusion in Xuchang Village, namely: technology sources, pioneers, followers, diffusers, imitators, and workers. Based on this, a schematic diagram of the technology diffusion network in Xuchang Village was drawn. The figure shows that the diffusion of folk musical instrument manufacturing technology in Xuchang Village had top-down, center-periphery structural characteristics, with obvious hierarchical levels. In addition, the technology diffusion network was characterized by the technology source and factory as the core, an irreversible transmission direction, and small-scale group diffusion.
Characteristics analysis of network
The network node increases, and the network density and centralization decrease. Overall, the network node increased, but the growth rate slowed down significantly. Especially in the last period, since the technology diffusion was basically completed in the village, it began to shift to diffusion outside the village, resulting in a small increase in the number of network nodes. Network density and centralization measurement analysis. The measured network density of technology diffusion in Xuchang Village was 0.0564, with a network centralization of 21.05%, which was significantly lower than that in previous periods (Table 4). Thus, network density was low, and the network structure was relatively loose, but with an obvious hierarchy and centralization trend. These characteristics are mainly related to the influence of the unidirectional nature of technology transmission and the limited path. In addition, since musical instrument manufacturing was more like a traditional culturalyl transmitted skill with certain technical barriers, technology diffusion among different actors was low, and it was difficult to establish a close connection.

Some principal nodes played a key role in the network of technology diffusion. In terms of individuals, early followers played a linking role in technology diffusion, enabling the technology to spread rapidly among friends, relatives, neighbors, and neighboring villages. The effect on the diffusion and re-diffusion was even stronger than that of local factories. Structural hole measurement analysis showed that the nodes with higher effective scale and efficiency were musical instrument factories. They were at the hub of the transmission and sharing of technology flow in the network, occupied more structural holes, and could best control interactions between other nodes. The effective scale of “ZY” and “SP” was 9.8 and 9, much higher than the average value of 2.12 (Table 5). This indicates that network centrality was monopolized by the source of technology and that regional development was overly dependent on the intermediary role of the source, which has absolute manipulation.

Burt used structural holes to represent nonredundant ties, proposing that “nonredundant contacts are connected by structural holes, and a structural hole is a nonredundant tie between two actors”41. Structural holes can provide opportunities for their occupants to gain “information benefits" and “control benefits” and thus have a competitive advantage over members in other positions in the network. The pioneers and followers, became structural holes between the technology source and local skilled workers and had a competitive advantage while mastering and diffusing the technology. In the early days of industrial development, local musical instrument factories acquired technology from the information source and passed it on to friends, relatives, and followers, thus functioning like gatekeepers. As early followers from Xuchang Village returned to the village to start their own businesses and form a regional group, the local musical instrument factories were still the important intermediaries for communication between Xuchang Village and the information source. Soon after, the local musical instrument factories’ identities was changed from gatekeepers to liaisons.
Diffusion corridors
Based on the questionnaires and our previous analysis, the corridors of technology diffusion were found to be different at different stages of diffusion. Technology diffusion underwent a constantly changing and increasingly complex process of external introduction (business ties), intra-village diffusion (blood ties and geographical ties), and radiation diffusion to the periphery (geographical ties). The specific diffusion corridors were as follows:
Technology source → business ties → pioneers → business ties and geographical ties → followers → blood ties and geographical ties → diffusers → blood ties and geographical ties → imitators → geographical ties → workers.
We can see that the diffusion corridors changed several times. Business ties played an important role in the early stage of technology diffusion. In the middle stage (intra-village diffusion), blood ties were the main corridors of technology diffusion. The technology diffusion corridors were more Chinese in nature, demonstrating the “circle of friends” aspect of interpersonal interaction in Chinese society (i.e., the Differential Mode of Association)42. Here, technology diffusion began with one’s “own people”, such as relatives and friends, and spread to “outsiders”, such as related practitioners in neighboring villages and towns. This was in line with the law of information diffusion in interpersonal networks43. At the end of technology diffusion, the geographical ties were the main corridors of technology diffusion, and the Xuchang Village gradually became the technology diffusion center in the area (Fig. 4).
Under the “circle culture” of technology diffusion in Xuchang Village, diffusion started from relatives and spread to friends and neighbors and finally to people in neighboring villages or in the same area. Technology diffusion in the village was also characterized by technology isolation. The smaller clans acquired the musical instrument manufacturing technology relatively late, and not from the larger clans in the village. In China, village formation often occurs over the course of several hundred years. The clan concept is deeply rooted, involving complex conflicts of interest and competition between neighboring clans. It may appear to be selectively “temporarily disabled” by geographical proximity, resulting in “technological isolation” in areas close to the technology exchange. This phenomenon suggests that technological isolation exists not only in cities but also in agricultural areas44,45.
Evolution mechanism
Chance factors facilitate the new-technology introduction. Research has shown that in the context of a specific historical foundation, chance factors can give rise to the introduction of technology, build bridges between a region and the outside world, and open new development paths46. Chance factors operate in a specific historical environment to facilitate the new-technology introduction (Fig. 5).
Unique natural resources and similar production traditions are the basis of technology diffusion. The rapid diffusion of Xuchang Village’s musical instrument manufacturing technology couldn’t be separated from the local rich paulownia resources and the similar production tradition (wood processing). The former provided a tangible material basis for technology diffusion, while the latter provided an intangible spiritual basis for technology diffusion.
Business ties, blood ties, and geographical ties are the main corridors of production technology diffusion. Evolutionary economic geography believes that the convention is the track of evolution, thus forming a development path. It can be seen from the above measurement and analysis that business ties, blood ties, and geographical ties were important corridors for production technology diffusion. Among them, geographical ties provided the possibility for technology diffusion, business ties improved the efficiency of technology diffusion, and blood ties ensured the accuracy of technology diffusion. Business ties, blood ties and geographical ties together constituted an important corridor for the diffusion of manufacturing technology, promoting the formation of specialized communities and the innovation of regional industries.
Market demand is an important driving force for technology diffusion. The market was considered to be an important factor affecting the development of specialized communities, and changes in market demand will have a profound impact on the entire industry. When the market demand was large, the number of farmers learning the production technology of musical instruments increased, promoting the widespread spread of production technology in Xuchang Village. Once the supply exceeds the demand, it is easy to cause vicious competition within the industry, leading some musical instrument shop owners to suspend production or give up business, and hindering the spread of musical instrument production technology.
Cognitive proximity is a prerequisite for technology to spread and diffuse. Folk musical instrument technology was introduced in Xuchang Village by Dai Shiyong, who was able to do this because he had previously supplied raw materials to musical instrument factories in Shanghai. This helped him to introduce advanced musical instrument manufacturing technology quickly and accurately. Relational proximity enhances the quality and speed of technology diffusion. Relational proximity can generally be divided into two types: social relationships and kinship, both of which enhance the speed and quality of technology diffusion. The former built a bridge for the early diffusion of technology and supported the rapid accumulation of local talent. The latter can provide strong support for large-scale technology diffusion within a village and make technology diffusion more accurate and efficient. Geographical proximity facilitates rapid technology diffusion within a region. After the technology in Xuchang Village matured, it radiated to the surrounding villages. Not only were there similar family workshops, but some villages also engaged in soundboard processing, establishing positive interactions with the adjacent villages. Xuchang Village evolved into a “learning field” for the manufacture of musical instruments, and Guyang Town, the township where it is located, gradually developed into a specialized town in producing folk musical instruments.
Overall, there was a hierarchy of technology diffusion in Xuchang Village: technology source → pioneers → followers → diffusers → imitators. Technology diffusion was continuously transmitted downward through the corridors of business ties, blood ties, and geographical ties, based on cognitive proximity, relational proximity, and geographical proximity. It continuously diffused from the core to the periphery, eventually forming a technology diffusion network of the traditional handicraft-based specialized communities.
