近年来，我国经济由高速发展转变为中高速发展，经济发展进入新常态阶段。高技术产业出口规模一直处于较高水平，但是出口规模并不能真实地反映出口国际竞争力水平，出口产品的技术含量和质量才是关键，其直接的体现就是高技术产业出口技术复杂度。因此，提升我国高技术产业出口技术复杂度以实现出口国际竞争力的提升，已成为当前关键任务。生产性服务业为生产活动提供中间产品投入，在发展过程中不断吸收现代技术，对高技术产业的技术提升也具有重要推动作用。本文将从产业集聚的视角研究生产性服务业对高技术产业出口技术复杂度的影响，以寻求促进高技术产业出口技术复杂度的提升以增强我国高技术产业出口竞争力的途径。

本文首先对研究思路、具体内容和研究方法进行系统叙述，并对相关文献进行综述，然后从相关概念和理论基础入手，对相关概念和理论进行阐述；其次，从理论层面分析生产性服务业集聚对我国高技术产业出口技术复杂度的影响机制；再次，分析生产性服务业现状和高技术产业现状，并对生产性服务业集聚和高技术产业出口技术复杂度水平进行测度和分析；最后，构建计量模型，借鉴已有理论框架进行实证分析探究生产性服务业集聚对我国高技术产业出口技术复杂度的影响，验证生产性服务业集聚对我国高技术产业出口技术复杂度的影响机制，并对实证结果进行分析。

总体来说，我国生产性服务业规模逐渐扩大，集聚水平也是平稳上升，东部地区的产业集聚水平高于中西部地区。高技术产业的出口规模也呈现总体上升的趋势，但出口技术复杂度在全球范围内属于较低水平。国内范围来看，五个细分行业出口技术复杂度差异不大，但分地区存在明显异质性。本文理论分析与实证结果表明，生产性服务业集聚显著促进了高技术产业出口技术复杂度的提升，且存在地区异质性和行业异质性。进一步分析发现，技术扩散和成本节约是生产性服务业集聚推动高技术产业出口技术复杂度提升的重要渠道。最后，本文从促进生产性服务业集聚方面就如何提高出口技术复杂度提出了相关政策建议。

In recent years, my country's economy has changed from high-speed development to medium-high-speed development, and economic development has entered a new normal stage. The export scale of high-tech industries has always been at a relatively high level, but the scale of exports cannot truly reflect the level of international competitiveness of exports. The technical content and quality of export products are the key, and the direct manifestation is the technical complexity of high-tech industry exports. Therefore, it has become a key task at present to improve the technical complexity of my country's high-tech industry exports in order to improve the international competitiveness of exports. The producer service industry provides intermediate product input for production activities, and continuously absorbs modern technology in the process of development, which also plays an important role in promoting the technological upgrading of high-tech industries. From the perspective of industrial agglomeration, this paper studies the impact of producer services on the technical complexity of high-tech industry exports, in order to seek ways to promote the improvement of high-tech industry export technical complexity and enhance my country's high-tech industry export competitiveness.

This paper first systematically describes the research ideas, specific contents and research methods, and summarizes the relevant literature, and then starts from the relevant concepts and theoretical basis, and expounds the relevant concepts and theories; secondly, analyzes the agglomeration of producer services from the theoretical level Influence mechanism on the technical complexity of my country's high-tech industry exports; thirdly, analyze the status quo of producer services and high-tech industries, and measure and analyze the agglomeration of producer services and the level of technical complexity of high-tech industry exports; finally, Constructing an econometric model, drawing on the existing theoretical framework to conduct empirical analysis to explore the impact of producer service industry agglomeration on the technical complexity of my country's high-tech industry exports, and verifying the impact mechanism of producer service industry agglomeration on my country's high-tech industry export technology complexity. Analyze the empirical results.

In general, the scale of my country's producer service industry has gradually expanded, and the level of agglomeration has also risen steadily. The level of industrial agglomeration in the eastern region is higher than that in the central and western regions. The export scale of high-tech industries also showed an overall upward trend, but the technical complexity of exports was relatively low in the world. From a domestic perspective, the export technical complexity of the five sub-sectors is not very different, but there is obvious heterogeneity in different regions. The theoretical analysis and empirical results of this paper show that the agglomeration of producer services significantly promotes the improvement of the technical complexity of high-tech industry exports, and there are regional heterogeneity and industry heterogeneity. Further analysis finds that Technology diffusion and cost saving are important channels for the agglomeration of producer services to promote the increase of technological complexity of high-tech industry exports.Finally, this paper puts forward relevant policy suggestions on how to improve the technical complexity of exports from the perspective of promoting the agglomeration of producer services.
