摘要
提高东北三省R&D投入对潜在产出的贡献率,对促进东北三省经济新一轮快速增长具有重要意义。本文采用面板数据模型研究东北三省R&D要素对潜在产出的贡献率。实证结果表明,东北三省物质资本对潜在产出的贡献率较大,其次是R&D投入,而劳动力投入的贡献率相对最低。说明东北三省的物质资本投入对潜在产出的影响仍占主导地位,R&D投入对潜在产出的影响力正在增大;东北三省比较而言,辽宁省R&D投入对潜在产出贡献率最大,吉林省次之,黑龙江省最小。最后,本文给出提高东北三省R&D投入贡献率的政策建议。
It is very important for new growth to enhance the contributions of R＆D inputs to potential output. The article studies the contributions of R＆D inputs to potential output in Northeast provinces with panel data model. The results show that the contributions from physical capital in Northeast provinces are larger, and that from R＆D inputs are less, that from labor inputs are the lowest. Which means that effects from physical capital inputs take the leading role, and effects from R＆D inputs are more and more stronger. Among Northeast Provinces, the contribution of Liaoning Province is the largest, next is Jilin Province, and that of Heilongjiang Province is the lowest. On basis of this, the article gives some Policy implications to improve contributions from R＆D inputs to potential output.
