The Empirical Study Of The Impact Of Upstream Monopoly On Dual Margin Of Chinese Firm's Export

In the four decades of reform and opening up,downstream product market of China has basically achieved perfectly competitive."Private enterprises dominate the downstream market competition,and large and medium-sized state-owned enterprises dominate the upstream market monopoly" has become the domestic status quo.With the rise of New-New Trade Theory,the dual structural decomposition of macro trade flows from a micro perspective also provides a new perspective for exploring the internal drivers of trade growth.President Xi Jinping pointed out in the report of the 19 th CPC National Congress: "China's economy has shifted from a high-speed growth phase to a high-quality development phase," and stressed that it is necessary to "improve the efficiency of resource allocation efficiency,promote the concentration of resources to quality enterprises and products,and promote the freedom of innovation." Today,China's industrial enterprises are facing with industrial upgrading and transformation.It is of practical significance to explore the influence of upstream industry monopoly on the export growth of downstream industries by combining the dual marginal theory and from the relationship between upstream and downstream industries in China,In this paper,we make a simple theoretical analysis and model deduction for the channel of upstream monopoly influence on the dual margin of China's export intensive,and draws on the model and variable selection of Minetti and Zhu(2011)to construct the upstream monopoly to export to downstream enterprises in China.An econometric model that aggregates marginal and extended marginal impacts and an econometric model of the role channel.Secondly,using the matching data of China Industrial Enterprise Database and China Customs Database and the "China Input-Output Table",we measured the intensive marginal and extended margin of China's export enterprises from 2000 to 2011,and the upstream industry monopoly indicators of 84 sub-sectors.Other enterprise-level control variables.Using the two-stage system GMM econometric analysis method,we empirically test how China's upstream monopoly affects the export margin and expansion margin of the enterprise,and examine the robustness of the empirical analysis by replacing variable indicators,conducting placebo tests and other mechanisms.And further empirical tests on the channels of upstream monopoly affecting the dual margins of Chinese enterprises' exports.The study found that: First,the upstream monopoly significantly inhibits the marginal and expansionary growth of China's export intensive;second,the upstream monopoly has significant differences in the binary marginal effects of different downstream trading companies and different ownership enterprises.The upstream monopoly significantly inhibits the binary margin of export of general trade enterprises and local enterprises,and its inhibitory effect is higher than the average suppression effect on downstream enterprises,but the negative impact on the binary margin of export of processing trade enterprises and foreign-funded enterprises is not obvious.Third,the impact of upstream monopoly on the marginal and extended margins of downstream enterprises' export intensiveness is mainly achieved by increasing the price of intermediate products and increasing the production costs of downstream enterprises,and inhibiting the reduction of productivity and innovation and research.Fourth,the upstream monopoly Severely occupied the space for high-quality growth of China's domestic production and enterprise exports.Finally,this paper combines the basic conclusions drawn from empirical analysis,from the perspective of upstream monopoly,discusses how to promote the dual marginal improvement of Chinese enterprises' exports,and proposes four policy recommendations.
