我国经济已由高速增长阶段转向高质量发展阶段，制造业发展在创新、协调、绿色、开放、共享五大维度有所突破，其理论逻辑和实践逻辑与新发展理念高度一致，提高制造业发展水平成为现代化强国建设的本质需求。新发展阶段制造业空间格局不断发生变化，我国当前的制造业发展水平仍然具有地区差异性，制造业产业结构的发展较之新发展理念和高质量发展的要求仍存在差距，把握制造业空间布局，促进制造业有序转移，利于产业布局进一步优化，增强区域协同，推进产业进一步转型、转移和升级，充分发挥区域比较优势。

本文首先梳理了近年来学者们关于新发展理念下我国制造业高质量发展的内涵界定、新发展理念下空间格局的相关研究、制造业网络溢出效应的相关文献。其次，通过深入新发展理念下我国制造业发展的内涵界定，确定制造业发展水平指标体系构建的理论基础，选用熵权法从创新发展、协调发展、绿色发展、开放发展、共享发展五个维度完成除西藏、港澳台外我国30个省份 2012-2021年中国制造业发展水平评价指标体系的构建，明确制造业阶段发展水平在全国各地区层面的具体状况、地区差异和总体特征。基于测算结果，选用社会网络分析方法研究其时空特征，地区之间制造业发展相互作用，向周围地区多维度溢出。同时以此为基础开展结合引力模型与社会网络分析的制造业空间布局研究：中心性分析，对地区间制造业联系强度进行研究；结构洞模型，对制造业发展网络中省份担任的角色进行研究；凝聚子群，研究由制造业网络中具有较强联系和影响省份产生的集聚子群。最后，为进一步明晰制造业是否存在溢出效应及其形成原因，本文引入制造业结构数据，基于高位架构理论以及新经济地理理论，研究资源配置视角下地区间溢出效应，对制造业区域发展提速提质具有重要意义。研究结论如下：

（1）新发展理念下，各省制造业发展水平形成了明显的“中心-外围”式空间结构，即东部为“核心”、中西部为“外围”，省际单元制造业发展水平的空间相关性明显。

（2）各省制造业发展过程中存在明显的空间相关性，且High-High型集聚与Low-Low型集聚频次最高，制造业发展水平较高与较低的省份往往会各自聚集。

（3）新发展理念下，全国30个省份之间单向与双向关联数量持续增多，网络整体形态逐渐稠密。北京、江苏、上海、广东、浙江、湖北等地持续处于网络的中心位置，云南、海南及青海、甘肃、新疆等西部地区持续处于网络的边缘位置，制造业地区间发展出现一定“马太效应”。总体来看，研究区间内制造业关联网络总体关联性逐年显著增强，区域间差距正在逐年减小。

（4）多数省份制造业对外辐射范围不断扩大，对外界的吸引力逐渐增强；北京、上海、广东等领先省份及湖北、四川等节点省份处于结构洞位置，具有领先发展优势；全国制造业关联网络存在4个二级凝聚子群，子群内部成员地理位置相近，制造业发展水平并不均衡。

（5）省域间制造业溢出效应明显。内部形成机制结果显示：影响制造业溢出的因素主要是创新发展，其次是协调发展和共享发展，绿色发展虽然存在正向影响但并非主要因素，而开放发展作用不足。外部形成机制结果表明：财政支持和人力资本是促成制造业溢出效应的主要因素，制造业投入作用机制表现强劲，信息化水平作用有待加强，城镇化水平与外资投入作用尚需发掘。

China's economy has shifted from a stage of high-speed growth to a stage of high-quality development. The development of the manufacturing industry has made breakthroughs in the five dimensions of innovation, coordination, green, openness, and sharing. Its theoretical and practical logic are highly consistent with the new development concept, and improving the level of manufacturing development has become an essential requirement for building a modern strong country. The spatial pattern of the manufacturing industry in the new development stage is constantly changing, and the current level of development of China's manufacturing industry still has regional differences. There is still a gap in the development of the manufacturing industry structure compared to the requirements of new development concepts and high-quality development. Grasping the spatial layout of the manufacturing industry, promoting orderly transfer of the manufacturing industry, further optimizing the industrial layout, enhancing regional coordination, promoting further transformation, transfer and upgrading of industries, and fully leveraging regional comparative advantages.

This thesis first reviews the definition of the connotation of high-quality development of China's manufacturing industry under the new development concept, relevant research on the spatial pattern under the new development concept, and relevant literature on the network spillover effect of the manufacturing industry in recent years. Secondly, by deepening the definition of the connotation of China's manufacturing development under the new development concept, we determined the theoretical basis for the construction of the manufacturing development level indicator system, and selected the entropy method to complete the construction of the evaluation indicator system of China's manufacturing development level from 2012 to 2021 in 30 provinces except Xizang, Hong Kong, Macao and Taiwan from the five dimensions of innovative development, coordinated development, green development, open development, and shared development, so as to clarify the specific situation, regional differences, and overall characteristics of the development level of the manufacturing stage in all regions of the country. Based on the calculation results, the social network analysis method is used to study its spatiotemporal characteristics, the interaction of manufacturing development between regions, and the multidimensional spillover to the surrounding areas. At the same time, based on this, research on the spatial layout of manufacturing industry combining gravity model and social network analysis will be carried out: centrality analysis will be conducted to study the strength of manufacturing industry connections between regions; Structural hole model, studying the roles played by provinces in the development network of manufacturing industry; Agglomeration subgroup is a study of agglomeration subgroups generated by provinces with strong connections and influence in the manufacturing network. Finally, to further clarify whether there are spillover effects in the manufacturing industry and the reasons for their formation, This thesis introduces structural data of the manufacturing industry, based on high-level architecture theory and new economic geography theory, to study the spillover effects between regions from the perspective of resource allocation, which is of great significance for accelerating and improving the quality of regional development in the manufacturing industry. The research conclusion is as follows:

(1) Under the new development concept, the development level of manufacturing industry in each province has formed a clear "center periphery" spatial structure, with the eastern region as the "core" and the central and western regions as the "periphery". The spatial correlation of inter provincial unit manufacturing development level is obvious.

(2) There is a clear spatial correlation in the development process of manufacturing industry in each province, and the High High and Low Low types of agglomeration have the highest frequency. Provinces with higher and lower levels of manufacturing development tend to cluster separately.

(3) Under the new development concept, the number of one-way and two-way connections between 30 provinces in China continues to increase, and the overall form of the network is gradually becoming dense. Beijing, Jiangsu, Shanghai, Guangdong, Zhejiang, Hubei and other regions continue to be at the center of the network, while Yunnan, Hainan, Qinghai, Gansu, Xinjiang and other western regions continue to be at the edge of the network. There is a certain "Matthew effect" in the development of manufacturing industries between regions. Overall, the overall correlation of the manufacturing industry correlation network within the research area has significantly increased year by year, and the regional gap is decreasing year by year.

(4) The manufacturing industry in most provinces continues to expand its scope of external radiation and its attractiveness to the outside world is gradually increasing; Leading provinces such as Beijing, Shanghai, and Guangdong, as well as node provinces such as Hubei and Sichuan, are located in structural holes and have leading development advantages; There are four secondary cohesive subgroups in the national manufacturing industry association network, with members within the subgroups having similar geographical locations and uneven levels of manufacturing development.

(5) The spillover effect of manufacturing industry between provinces is significant. The internal formation mechanism results show that the main factors affecting manufacturing spillovers are innovative development, followed by coordinated and shared development. Although green development has a positive impact, it is not the main factor, and the role of open development is insufficient. The results of external formation mechanisms indicate that fiscal support and human capital are the main factors promoting spillover effects in the manufacturing industry. The mechanism of manufacturing investment is strong, and the role of informatization level needs to be strengthened. The level of urbanization and the role of foreign investment still need to be explored.
