【摘要】：本文從成本加成率角度分析企業(yè)獲取創(chuàng)新壟斷租金的微觀機(jī)制,一方面,產(chǎn)品創(chuàng)新通過(guò)增加市場(chǎng)份額降低產(chǎn)品需求彈性,企業(yè)可以索要更高的加成率,即"市場(chǎng)份額效應(yīng)";另一方面,產(chǎn)品創(chuàng)新帶來(lái)的生產(chǎn)率提升促使企業(yè)邊際成本降低,進(jìn)而提升加成率,即"成本效應(yīng)"。我們理論分析了"市場(chǎng)份額效應(yīng)",并在成本加成率和生產(chǎn)率估計(jì)模型中考慮"成本效應(yīng)",將企業(yè)創(chuàng)新納入其生產(chǎn)率動(dòng)態(tài)過(guò)程。利用2001-2007年中國(guó)工業(yè)企業(yè)數(shù)據(jù)研究驗(yàn)證了以下理論預(yù)期:產(chǎn)品創(chuàng)新通過(guò)增加市場(chǎng)份額顯著提升了企業(yè)成本加成率,與此同時(shí),產(chǎn)品創(chuàng)新也通過(guò)降低邊際成本顯著提升成本加成率,但"成本效應(yīng)"弱于"市場(chǎng)份額效應(yīng)"�？紤]創(chuàng)新的自選擇、測(cè)量誤差和內(nèi)生性問(wèn)題后結(jié)論仍然穩(wěn)健。
[Abstract]:This paper analyzes the micro mechanism of enterprises obtaining innovative monopoly rent from the angle of cost addition rate. On the one hand, product innovation reduces the elasticity of product demand by increasing market share, and enterprises can demand a higher addition rate. On the other hand, the productivity increase caused by product innovation leads to the reduction of marginal cost and the increase of addition rate, which is called "cost effect". We theoretically analyze the "market share effect", and consider the "cost effect" in the cost addition rate and productivity estimation model, and bring enterprise innovation into its productivity dynamic process. By using the data of Chinese industrial enterprises from 2001 to 2007, this paper verifies the following theoretical expectations: product innovation significantly increases the cost addition rate by increasing the market share, and at the same time, product innovation significantly increases the cost addition rate by reducing the marginal cost. But the cost effect is weaker than the market share effect. After considering innovative self-selection, measurement error and endogeneity, the conclusion is still robust.
