摘要
基于服务业占比、服务业增加值以及人均服务业增加值三个维度进行度量的中国服务业增长区域失衡状态正愈演愈烈。本文从知识产权保护(IPR)实际强度与"最适强度"偏离度的视角解读了中国服务业增长区域失衡的理论机制,并借助于不同的计量模型开展间接论证和直接论证,基于多样化知识产权保护指标和基于服务业企业微观数据的多次回归均得到了较为稳健的研究结论。研究发现:知识产权保护显著地促进了中国的服务业增长,而且中国知识产权保护实际强度尚未达到理论上的"最适强度";东中西部地区存在各自理论上的知识产权保护"最适强度",相对于东部地区而言,中西部地区知识产权保护实际强度与自身"最适强度"的偏离度较大,导致中西部地区原先落后于东部地区服务业增长的劣势进一步加剧,中国服务业增长的区域失衡越发严峻。
Summary:With the fast growth in China's services in recent years,the percentage of services in China's GDP has increased.The percentage of value added by services in China's GDP reached 51.6%in 2016,exceeding the contribution of the next largest industry by 11.8%.Tremendously large regional imbalances also exist in China.The regional imbalances in China's growth in services,measured by the proportion of services in GDP,the value-added by services and the value-added per capita by services,have become increasingly intense.This paper investigates these regional imbalances from the perspective of the difference between the actual strength and the optimal strength of intellectual property rights protection(IPR).Because services are a vital part of the economy,this paper explains regional imbalances in services using econometric models derived from economic growth theories.An analytical framework is constructed that reveals the mechanisms by which differences between the actual and optimal strengths of IPR affect the regional imbalances in China's growth in services.Both direct and indirect verification are used as an empirical exercise.The impact of differences between the actual strength and the optimal strength of IPR on regional imbalances in China's growth in services is indirectly verified using subsamples of eastern,central and western China.Next,this paper directly verifies this impact by constructing variables capturing the regional imbalances in China's growth in services and the differences between the actual strength and optimal strength of IPR.To resolve the issue of endogeneity in the empirical model,a distance index and the railway density are used as instrumental variables(IVs).As a robustness check,this paper tests the effect of differences between the actual and optimal strengths of IPR on regional imbalances in China's growth in services with micro-data.This is seldom done in the literature on service economics and contributes to the search for micro-foundations for the regional imbalances in the gr
