本文以我国1998—2014年各省份四种所有制企业的数据为样本,将空间因素纳入到知识生产函数中,尝试性地分析了不同所有制企业之间的创新溢出大小与边界。研究结论显示:(1)创新溢出具有体制临近性,即同种所有制企业之间的创新溢出较大;(2)不同所有制企业间创新溢出具有非对称性,民营企业成为创新溢出的最大吸收方,国有企业难以获取其他企业创新投入的外部性,成为主要溢出方,港澳台资企业与外资企业之间具有“挤占效应”;(3)就不同所有制企业创新溢出的边界而言,国有企业之间在全国范围内存在溢出效应,民营企业间的溢出边界为1450千米,港澳台资企业间、外资企业间均为1650千米;(4)就不同所有制企业创新产出的影响因素而言,企业自身的研发经费与研发人员投入仍是创新产出的重要保障。本文的研究结果对当前我国创新驱动发展战略、企业间协同创新、外商投资政策的改革方向和政策调整具有一定的指导意义。
Taking the data of four kinds of ownership enterprises in all provinces of our country from 1998 to 2014 as samples, this paper incorporates spatial factors into the knowledge production function and tries to analyze the size and boundary of innovation spillover among different ownership enterprises tentatively. The conclusions of the study are as follows: (1) The innovation spillover has the institutional proximity, that is, the spillover of innovation among the same kinds of ownership enterprises is larger; (2) The asymmetry of innovation spillovers among different ownership enterprises and the private enterprise becomes the biggest absorption spill , State-owned enterprises can hardly obtain the externalities of other enterprises’ innovation inputs and become the main spillover parties, and the “crowding-off effect” between Hong Kong and Maucao-Taiwan-funded enterprises and foreign-funded enterprises; (3) For the boundary of innovation spillover among different ownership enterprises, The spillover effect exists among enterprises across the country. The spillover boundary between private enterprises is 1,450 km, and the number of foreign-funded enterprises in Hong Kong, Maucao and Taiwan is 1,650 km. (4) Factors influencing the innovation output of different ownership enterprises In terms of enterprise R & D funding and R & D personnel input is still an important guarantee for innovation and output. The research results of this paper are of guiding significance to the current innovation-driven development strategy, collaborative innovation among enterprises, the reform direction of foreign investment policies and the policy adjustment.
