3.2 Database <strong>of</strong> high tech firms<br />

The M<strong>in</strong>istry <strong>of</strong> Science and Technology (MOST) conducted an annual survey <strong>of</strong> unlisted high<br />

tech companies from 2001 to 2005. The surveyed companies are approved as high tech enterprises<br />

by the local Science and Technology Bureau, and are permitted to locate <strong>in</strong> the National Innovative<br />

and High Technology Industrial Development zones <strong>in</strong> designated cities throughout Ch<strong>in</strong>a. 9<br />

The<br />

numbers <strong>of</strong> companies <strong>in</strong> the surveys are: 8,298 (for 2001), 9,743 (2002), 11,470 (2003), 13,261<br />

(2004), and 15,459 (2005). Out <strong>of</strong> the 58,231 firm-year observations, we exclude firms that report<br />

no R&D expenditure or have no R&D personnel dur<strong>in</strong>g the sample period, which leaves us with<br />

40,845 firm-year observations. 10 Our regression models use one-year-lagged variables, thus firms<br />

that do not have data <strong>in</strong> at least two consecutive years are excluded. The f<strong>in</strong>al sample <strong>in</strong>cludes<br />

23,995 firm-year observations.<br />

The surveyed samples are expected to cover all <strong>of</strong> Ch<strong>in</strong>a’s unlisted high tech companies <strong>in</strong><br />

9 In Ch<strong>in</strong>a, as <strong>in</strong> many countries, high tech firms <strong>in</strong> the special zones enjoy tax preferences and other policy<br />

support.<br />

10 Although our companies are located <strong>in</strong> special zones for high tech firms where they could enjoy certa<strong>in</strong> tax<br />

breaks and other subsidies, we do f<strong>in</strong>d some firms that do not seem to be actively engaged <strong>in</strong> R&D. It may be<br />

the case that these firms surreptitiously ga<strong>in</strong> admission to the special high tech zones to enjoy the benefits, or<br />

they simply desire to be branded as high tech. For example, Shijiazhuang Zhenx<strong>in</strong>g Cloth<strong>in</strong>g Production Co.<br />

Ltd., has not obta<strong>in</strong>ed the high-tech enterprise qualification but is located <strong>in</strong> Shijiazhuang High-tech Industrial<br />

Development Zone for preferential treatment.<br />
